Best Time To Visit Tanzania - Rift And Ridge Safaris

BEST TIME TO VISIT TANZANIA A Month-by-Month Planning Guide for Safari, Beach, and Kilimanjaro

The best time to visit Tanzania for a wildlife safari is during the dry season, from late June through October. For the Serengeti calving season and fewer crowds, January to March is excellent. Zanzibar is best visited between June and October, or December to February. For Kilimanjaro, the clearest summit windows are January to February and June to October. Tanzania’s two rainy seasons the long rains (March to May) and the short rains (November) are generally the least ideal for first-time visitors, though green-season safaris offer genuine advantages for experienced travelers.

This question gets complicated fast because Tanzania is a large country with multiple ecosystems, and “best time” depends entirely on what you want to see and where you want to go. A month that is ideal for witnessing the Mara River crossings in the northern Serengeti may be the same month that Zanzibar’s east coast sees its heaviest rain. A month that is perfect for diving at Pemba Island may be the least convenient for climbing Kilimanjaro.

This page breaks it down properly by season, by month, by destination, and by what you specifically want to experience. Use it as a planning reference alongside your conversation with Rift & Ridge Safaris, where we match specific travel windows to the best possible itinerary for what you want to see.

QUICK ANSWERS

What is the best month to visit Tanzania? There is no single best month, it depends on which experience you are prioritising. For the Mara River crossings and peak dry-season game viewing, August and September are the strongest months. For calving season and predator activity in the southern Serengeti, January and February are exceptional. For a first visit combining the Northern Circuit with Zanzibar, July through October offers the most reliable conditions across both. If forced to name one month for a first-time visitor with no specific priority, September is the answer, dry season peak, crossing season, reliable Zanzibar weather, and the widest range of experiences available simultaneously.

When is the rainy season in Tanzania? Tanzania has two rainy seasons. The long rains run from late March through May the heaviest and most disruptive period, during which some remote camps close and certain roads become impassable. The short rains run from late October through December lighter, less predictable, and generally more manageable for travel. Both rainy seasons are driven by the Intertropical Convergence Zone moving across the country. The coast and islands tend to receive rain earlier and more heavily than the interior safari areas.

What months should I avoid visiting Tanzania? For most visitors, April and May represent the most challenging travel months the long rains are at their heaviest, road conditions deteriorate, and several mobile camps in the Serengeti and remote southern parks close entirely. Tanzania is not impossible to visit in April or May, but it requires accepting limitations on where you can go and what you can do. For Zanzibar specifically, April and May bring the heaviest rainfall of the year and are best avoided for a beach holiday.

Is Tanzania good to visit in December? December is a reasonable shoulder month for safari travel. The short rains, which typically begin in late October or November, are usually tapering by December in most safari areas. Camp rates begin to drop from their October peak. The parks are quieter than July to October. The trade-off is some unpredictability December can be fully dry in some years and carry lingering rain in others. For Zanzibar, December is generally excellent, with the rains finished and the northeast monsoon bringing calm, clear conditions to the north and east coasts. The Christmas and New Year period sees a spike in demand and prices that partially offsets the shoulder-month advantages.

What is the best time to see the wildebeest migration? The migration is a year-round event the wildebeest are always somewhere in the Serengeti-Mara ecosystem. For the Mara River crossings, the most visually dramatic phase, July to October is the window. For calving season newborn wildebeest, extraordinary predator activity, fewer crowds January to March at Ndutu in the southern Serengeti. For the Grumeti River crossings in the Western Corridor, June to July. There is no single “migration month” the right answer depends on which chapter of the story you want to witness.

What is the best time to climb Kilimanjaro? The two clearest and most reliable windows are January to February and June to October. Both periods offer the best summit visibility, lowest precipitation on the mountain, and the most stable trail conditions. The worst months are March to May the long rains bring heavy cloud cover, wet trails, and reduced visibility at the summit. December is also manageable in most years. The mountain can technically be climbed year-round, but summit success rates are meaningfully lower outside the recommended windows.

UNDERSTANDING TANZANIA’S CLIMATE

Tanzania spans from sea level on the Indian Ocean coast to 5,895 meters at the summit of Kilimanjaro, and the climate varies correspondingly. Understanding the basic pattern makes the month-by-month detail easier to navigate.

THE TWO RAINY SEASONS

Tanzania’s rainfall is driven by the Intertropical Convergence Zone (ITCZ), a band of atmospheric instability that moves north and south across the equator with the seasons, bringing rain as it passes.

The long rains (Masika): Late March through May. The ITCZ passes northward across Tanzania during this period. Rainfall is heaviest, most consistent, and most widespread. The coast and northern highlands receive the most rain; the southern and western interior receive less but are still significantly affected. This is Tanzania’s principal growing season the landscape transforms from dry ochre to vivid green within weeks of the rains’ arrival.

The short rains (Vuli): Late October through December. The ITCZ returns southward. Shorter, lighter, and more unpredictable than the long rains. Many years the short rains are barely noticeable in the interior safari areas a week of afternoon showers followed by clear conditions. On the coast and islands, the short rains are more consistently felt.

The dry season: June through October. The ITCZ has moved north of Tanzania entirely, and the southeast trade winds bring dry, stable conditions across the country. Vegetation dries and thins, waterholes shrink, and wildlife concentrates around permanent water sources. This is peak safari season for good practical reasons: visibility is longer, animals are more predictable, and the roads are in their best condition.

The inter-season: January to February. A warm, often dry period between the short rains and the long rains. Conditions in the interior are generally good for safari clear skies, lower humidity than peak dry season, and the calving season in the southern Serengeti making it one of the most rewarding times of year for wildlife watching.

REGIONAL CLIMATE VARIATION

Tanzania is not climatically uniform. The coast and islands experience the rainy seasons earlier and more intensely than the interior. The southern highlands around Iringa gateway to Ruaha are drier than the north and receive significantly less rainfall even during the long rains. The western regions (Mahale, Katavi) follow a different rainfall pattern to the north, with their peak rains arriving earlier (February to April) and some parks closing from approximately February to May. Kilimanjaro creates its own micro-climate the mountain generates cloud and rain on its slopes year-round, though the summit zones are clearest during the two recommended climbing windows.

TEMPERATURES

Tanzania’s safari areas sit between 1,200 and 1,800 meters above sea level, which moderates temperatures significantly compared to the coast.

Northern safari areas (Serengeti, Ngorongoro, Tarangire): Daytime temperatures 24–30°C during the dry season, cooling significantly at night Ngorongoro rim temperatures drop to 5–10°C on cold dry-season nights. Daytime temperatures rise toward 32–35°C in the hot inter-season period (November to February at lower elevations).

Zanzibar coast: 26–32°C year-round. Humidity is higher than the interior. The northeast monsoon (December to March) brings pleasant sailing conditions; the southeast monsoon (May to October) keeps the north coast calm and clear.

Kilimanjaro summit zone: −10°C to −20°C at night at the summit. Temperature drops approximately 6°C per 1,000 meters of altitude gain base camp at 1,800 meters may be 25°C while the summit is −15°C simultaneously.

THE DRY SEASON: JUNE TO OCTOBER Peak Safari Season

This is peak safari season, and it earns that status. Vegetation is lower, waterholes concentrate animals, sight lines are longer, and road conditions are at their best. Game viewing in Tarangire during August and September is arguably the best in East Africa elephant herds in the hundreds converge on the Tarangire River, the only permanent water source for miles in every direction. The Mara River crossings in the northern Serengeti reach their peak between August and October.

WHAT THE DRY SEASON DELIVERS

Wildlife concentration: As seasonal water sources dry up, animals are forced to permanent rivers and waterholes. The predictability of sightings increases dramatically a game drive that might produce 3 or 4 species in the wet season regularly produces 10 or 12 in the dry season because all of them are drawn to the same limited water.

Predator activity: Predators work harder during the dry season because prey animals are more concentrated and more vulnerable. Lion hunts in the open, cheetah on the short-grass plains, leopard along the river systems dry season drives produce a higher frequency of active predator behaviors than any other period.

Road conditions: Unpaved tracks in the parks are at their firmest and most accessible. Remote camps that are unreachable during the rains operate fully. Charter flight schedules run without weather disruption.

Photography: Lower vegetation means unobstructed sight lines. The dust and golden light of the dry season produce a specific aesthetic warm tone, long shadows in the morning and evening, and animal subjects in an ochre landscape that is immediately recognisable as the African bush.

THE HONEST TRADE-OFFS

Higher prices: Most camps charge peak rates from July through October typically 20 to 40 percent above their shoulder rates. The best northern Serengeti camps sell out months in advance.

More vehicles: The Serengeti’s most popular sighting locations lion kills, cheetah hunts, crossing points on the Mara River attract multiple vehicles simultaneously during peak season. This is part of the reality of visiting and worth factoring into expectations. The northern Serengeti is less affected than the central Serengeti; private camps in the north tend to have fewer vehicles at sightings than public camps in the centre.

Dust: By September and October, the northern Serengeti and Tarangire are very dry. Dust is significant on game drives. Protect camera equipment and accept that the landscape has the parched quality of late dry season rather than the drama of the earlier dry months.

PEAK SEASON CROWD CALENDAR

The peak of peak season is August, schools in the northern hemisphere are on summer holidays, demand is at its absolute highest, and prices reflect this. July is nearly as busy. September remains strong. October is the transition month, still excellent wildlife, beginning to see the first rains in some areas, and prices starting to ease at the end of the month.

School holiday peaks to be aware of:

Northern hemisphere summer: July and August (UK, Europe, North America)
US Thanksgiving: late November (limited impact on Tanzania’s parks)
Christmas and New Year: 23 December to 4 January (significant demand spike, prices rise sharply)
Easter: variable, typically March or April (falls during the long rains limited impact on safari demand)

The practical implication: if July and August are your only travel window, book 9 to 12 months in advance for the best northern Serengeti camps during crossing season. Waiting until 3 months before departure and hoping for availability is a realistic plan only for the green season.

THE GREEN SEASON: NOVEMBER TO MAY What It Offers and What It Does Not

Tanzania’s two wet periods transform the landscape in ways that photographs from the dry season cannot prepare you for. The Serengeti turns green. The riverbeds fill. The birds arrive in extraordinary numbers. And the camps that remain open have far fewer guests.

THE SHORT RAINS: OCTOBER TO DECEMBER

October is a transition month the dry season ending, the first rains beginning in some areas, prices starting to move. In the northern parks, the short rains typically arrive as afternoon showers rather than all-day rain, and game viewing remains excellent through October. By November, rainfall is more consistent, vegetation begins to recover, and the migrating herds begin moving south through the eastern Serengeti toward Ndutu.

November is one of Tanzania’s most underrated safari months. The parks are notably quieter than October, rates at most camps drop 10 to 20 percent, the Serengeti is greening, and the herds are on the move southward in significant numbers. Wildlife encounters in November are excellent the resident predators are active, the landscape is photogenic, and the absence of the peak-season vehicle concentrations makes sightings more spacious.

December is generally good in the interior safari areas, with the short rains typically tapering. Zanzibar is at its best the northeast monsoon brings calm, clear water to the north coast, and temperatures are ideal. The Christmas and New Year period brings a demand and price spike that partially offsets the shoulder-month advantages; for travel in the last two weeks of December, book as early as peak season.

THE LONG RAINS: MARCH TO MAY

This is Tanzania’s most challenging travel period. The long rains arrive in late March and typically run through May, with April being the heaviest month in most years. Several mobile camps in the northern Serengeti close entirely the tracks become impassable for vehicles, and repositioning a mobile camp is impractical in the mud. Some remote southern camps also close during this period.

For most visitors particularly first-timers April and May are the months to avoid. Not impossible, but requiring careful management of expectations and itinerary design.

What April and May do offer: The lowest camp rates of the year 30 to 40 percent below peak at properties that remain open. The landscape at its most dramatic lush, vivid, and photographic in a way the dry season is not. Essentially no other tourists in the parks that remain accessible. The birding is extraordinary; thousands of migratory species present alongside Tanzania’s resident populations.

For experienced safari travelers who have already seen the parks at their peak, the green season Serengeti has a particular quality, quiet, misty, and intimate that some prefer to the crowded perfection of August.

THE INTER-SEASON: JANUARY TO FEBRUARY

January and February occupy a meteorological middle ground between the short rains and the long rains that makes them among the most compelling months in the Tanzania calendar. The interior safari areas are largely dry and clear. Temperatures are warm. The landscape still carries some of the green from the short rains. And the calving season is in full force in the southern Serengeti and Ndutu.

Up to 8,000 wildebeest calves born daily at the peak of calving season. Cheetah, lion, hyena, and wild dog hunting newborn calves on the open short-grass plains. The predator-to-prey ratio during this period is unlike any other time of year. Calving season at Ndutu is the most underrated wildlife experience in Tanzania extraordinary on its own terms, with fewer vehicles than the crossing season and a different, more intimate quality to the sightings.

January is also one of the best months for Zanzibar the northeast monsoon is at its peak, conditions on the north coast are ideal, and the demand from European visitors has not yet peaked.

MONTH BY MONTH: THE COMPLETE GUIDE

FEBRUARY

Safari conditions: Excellent. Peak of calving season. The most extraordinary predator activity of the entire year on the Ndutu plains.

Migration: Peak calving. The largest number of wildebeest calves on the plains simultaneously. Lion, cheetah, hyena, and wild dog all hunting actively.

Wildlife highlight of the month: The density of predator interaction during peak calving is unmatched anywhere in Africa at any time of year. A single drive in Ndutu in February can produce encounters with four or five apex predator species.

Zanzibar: Good. Still within the northeast monsoon window. North coast calm and clear.

Kilimanjaro: Good. Clear summit conditions. Recommended window.

Crowds: Low to moderate. Calving season is less visited than crossing season the northern Serengeti camps are quiet relative to their July to October occupancy.

Best for: Best predator activity of the year, calving season photography, Kilimanjaro, quiet safari. Avoid if: You specifically want the Mara River crossings or the Tarangire dry-season elephant concentration.

MARCH

Safari conditions: Variable. The long rains begin to arrive in late March, typically starting on the coast and moving inland. Interior safari areas remain largely accessible through early to mid-March. Game viewing is still strong the calving season is winding down and the herds are beginning to move northwest.

Migration: Herds starting to move northwest from Ndutu as the long rains push northward. Calving winding down.

Wildlife highlight of the month: The transition herds on the move, predators following, the Serengeti greening as the rains arrive.

Zanzibar: Beginning of the long rains on the coast. Swimming conditions deteriorating on the east coast. North coast more sheltered.

Crowds: Minimal. The lowest visitor numbers of the year.

Camp rates: 30 to 40 percent below peak at properties that remain open.

Best for: Budget travelers who have visited before and know what they are accepting, serious birders, green season photography. Avoid if: This is your first Tanzania trip, you want beach time in Zanzibar, or you are planning Kilimanjaro.

MAY

Safari conditions: Challenging but improving toward the end of the month. Rains typically begin to ease in late May. Parks that closed in April may begin to reopen. Game viewing for those who can access the parks is excellent the landscape is extraordinary and there are almost no other vehicles.

Migration: Herds beginning to move toward the Western Corridor as the rains ease. The western Serengeti starts to activate.

Wildlife highlight of the month: The Serengeti at its greenest and most photogenic. Late May can produce excellent game viewing as the rains ease and animals emerge from cover.

Zanzibar: Still rainy. Not recommended for the coast.

Kilimanjaro: Not recommended.

Crowds: Minimal. Transitioning from low season toward shoulder.

Camp rates: Low season. Some of the lowest rates of the year.

Best for: Experienced travelers comfortable with green-season conditions, those seeking maximum value, late May can work well for safari. Avoid if: First-time visitor, beach extension planned, Kilimanjaro on the itinerary.

JUNE

Safari conditions: Very good and improving rapidly. The long rains have ended. Camps that closed are reopening. The northern parks are drying out, vegetation is lowering, and wildlife viewing is significantly improving week by week.

Migration: Herds gathering in the Western Corridor. Grumeti River crossing season beginning in the second half of June. Excellent time for the Western Corridor.

Wildlife highlight of the month: The Grumeti River crossings smaller than the Mara River crossings but intense in their own right. The massive hippo pools of the Western Corridor visible alongside the crossing points.

Zanzibar: Excellent. The southeast monsoon arrives, bringing dry, sunny, and windy conditions ideal for the north coast beaches and kitesurfing on the east coast.

Kilimanjaro: Good. The dry season summit window is open.

Crowds: Low to moderate. Building toward peak season but not yet crowded. One of the best value months of the year strong conditions, reasonable rates.

Camp rates: Shoulder to peak transition. Rates rising from low-season lows.

Best for: Value-conscious travelers who want strong conditions without peak-season prices or crowds. Western Corridor migration and Grumeti crossings.

JULY

Safari conditions: Excellent. Full dry season. All parks open and fully operational. Migration in the northern Serengeti. Tarangire elephant concentrations building. Ngorongoro Crater year-round excellence.

Migration: Mara River crossing season beginning. Herds gathering in the northern Serengeti and beginning to cross into the Masai Mara. July crossings are typically smaller in scale than August and September but are happening with increasing frequency.

AUGUST

Safari conditions: Outstanding. Peak dry season. The Serengeti, Tarangire, and all northern parks at their best simultaneously. Migration crossings at their most frequent.

Migration: Peak crossing season. Herds crossing the Mara River in the highest numbers of the year. Multiple crossings possible on a single day. The wildlife experience that Tanzania is most famous for.

Wildlife highlight of the month: The Mara River crossings at peak frequency and scale. Alongside: Tarangire elephant herds at their largest, Ngorongoro year-round wildlife at its most reliably accessible, and predator activity extraordinary across all parks.

Zanzibar: Excellent. Clear, dry, and windy on the east coast. North coast ideal.

Kilimanjaro: Excellent. Clear summit conditions.

Crowds: The highest of the year. More vehicles in the northern Serengeti than any other month. Book the best camps 9 to 12 months ahead at some properties, 18 months is not excessive for August.

Camp rates: Highest of the year across all northern parks.

Best for: Everything simultaneously. The month that delivers the most, most reliably, across safari, beach, and climbing. The trade-off is entirely in the price and the crowds.

SEPTEMBER

Safari conditions: Outstanding. Late dry season. Conditions as strong as August in most parks. Crossing season continuing in the northern Serengeti.

Migration: Crossing season continuing September often produces the most dramatic individual crossings of the year as the herds begin returning southward and the crossing energy intensifies before the rains return.

Wildlife highlight of the month: Late-season crossings can be the most dramatic of the annual cycle as the herds gather for the southward return.

Zanzibar: Good to excellent. Southeast monsoon beginning to ease. North coast ideal. East coast settling.

Kilimanjaro: Excellent. Still within the recommended summit window.

Crowds: High but marginally less than August. Northern hemisphere summer holidays ending. A slight ease in vehicle numbers in the second half of September.

Camp rates: Peak, beginning to ease slightly at the end of the month.

OCTOBER

Safari conditions: Good to very good. Transition month the dry season at its dustiest in some parks, the first short rains beginning in others. Tarangire and the central Serengeti still excellent. Northern Serengeti crossing season winding down.

Migration: Herds beginning to move southward from the Masai Mara back through the eastern Serengeti. The crossing season is ending, but the herds moving south in October are a spectacle in their own right.

Wildlife highlight of the month: The southward movement of the herds through the eastern Serengeti a less photographed but significant phase of the migration cycle.

Zanzibar: Transition. The southeast monsoon easing. North coast conditions good. East coast settling toward calmer water.

Kilimanjaro: Good. Still within the recommended window, though the short rains can begin on the mountain from mid-October.

Crowds: Moderating. Northern hemisphere summer holidays finished. Vehicle numbers in the parks dropping noticeably from their August peak.

Camp rates: Beginning to move toward shoulder season. Good value relative to August, strong conditions relative to November.

Best for: Budget-conscious travelers who want dry-season conditions without peak-season prices or peak crowds. Strong across all northern parks.

NOVEMBER

Safari conditions: Good. The short rains arrive but are typically light and manageable in the interior. Game viewing in the northern parks remains strong the landscape is greening, the light is softer and more photogenic, and the parks are notably quiet.

Migration: Herds moving south through the eastern Serengeti toward Ndutu. The transition phase the cycle is resetting. Still significant numbers of animals visible on the plains.

Wildlife highlight of the month: A quieter Serengeti with the herds on the move south and the first flush of green transforming the landscape. Ndutu area beginning to attract the first herds returning to the calving grounds.

Zanzibar: Variable. Short rains on the coast. North coast more sheltered. East coast can be rough. Not ideal for a dedicated beach holiday but manageable.

Kilimanjaro: Variable. Short rains affecting the mountain. Not the recommended window but possible in dry years.

Crowds: Low. One of the least-visited months for safari. An underrated month for travellers who know what they are doing.

Camp rates: Shoulder to low. 10 to 20 percent below peak at most properties.

Best for: Experienced travelers who value space and value over peak conditions. Green-season photography.

DECEMBER

Safari conditions: Good, improving through the month. Short rains typically easing by December in the interior. Game viewing strong across all northern parks. Calving season beginning to build in the southern Serengeti toward the end of the month.

Migration: Herds arriving at Ndutu in the southern Serengeti. Calving season beginning to build in the second half of the month. Predator activity increasing.

Wildlife highlight of the month: The return of the herds to Ndutu and the beginning of calving season one of the most anticipated phases of the annual cycle.

Zanzibar: Very good. Short rains finished or finishing. Northeast monsoon arriving calm, clear conditions developing on the north coast. Excellent swimming and diving conditions through the month.

Kilimanjaro: Reasonable. Not the recommended window but possible the short rains are easing, and December summit attempts succeed in most years. Less predictable than January or July.

Crowds: Low through mid-December. Significant spike 23 December to 4 January Christmas and New Year demand pushes camp rates to peak levels.

Camp rates: Shoulder through mid-December. Peak rates 23 December to 4 January. Some of the best value of the year falls in the first three weeks of December.

Best for: December (1–20) is outstanding value good safari conditions, Zanzibar at its best, reasonable camp rates, and low crowds. The Christmas period is fine but expensive and crowded.

BEST TIME BY DESTINATION

SERENGETI NATIONAL PARK

Year-round viable the Serengeti is never empty and never disappointing. Within that, the timing determines which experience you have.

Northern Serengeti (Kogatende / Mara River crossings): July to October
Southern Serengeti and Ndutu (calving season): January to March
Western Corridor (Grumeti crossings): June to July
Central Serengeti (Seronera, year-round predators): Any month
Avoid: April to May if a mobile camp is part of the plan many close entirely

NGORONGORO CONSERVATION AREA

Year-round, with the crater performing reliably in all seasons. Some nuance:

Diving: Year-round, but October to March offers the best conditions
Avoid: April to May long rains, rough seas

THE DECISION FRAMEWORK What Is Your Priority?

Use this as a starting point. Most itineraries involve more than one priority we balance them based on your specific travel window.

I WANT THE MARA RIVER CROSSINGS: July to October. Northern Serengeti, Kogatende area. 4 to 5 nights minimum for realistic odds. Book 9 to 12 months ahead.

I WANT THE BEST PREDATOR ACTIVITY: January to February for calving season at Ndutu the densest predator hunting of the year. July to October for dry-season concentration hunting across all parks.

I WANT THE MOST VALUE FOR MONEY: November or June shoulder season rates, strong conditions, meaningfully fewer vehicles. December 1 to 20 is outstanding value if Zanzibar beach time is the priority.

I WANT TO AVOID CROWDS: November, January to February, or June. All offer strong wildlife with notably fewer vehicles than July to October.

I WANT TO CLIMB KILIMANJARO: January to February or August to September. Plan the safari immediately after the climb, not before.

I WANT A HONEYMOON (SAFARI + BEACH): June through October is the strongest combined window for both safari conditions and Zanzibar weather. January to February is the strongest alternative.

I WANT TO SEE WHALE SHARKS: November to February at Mafia Island. Combine with a Southern Circuit safari Ruaha and Nyerere as the mainland component.

I WANT CHIMPANZEES IN MAHALE: July to October. Allow a full travel day in each direction. Combine with Katavi for a western Tanzania circuit.

I AM A FIRST-TIME VISITOR WITH NO FLEXIBILITY: If you can only go in one period and have no specific wildlife priority, July to October is the answer. It delivers the most, most reliably, across every dimension of the Tanzania experience.

FIRST-TIMER RECOMMENDATION

If this is your first Tanzania safari and you have flexibility, aim for late July through September. You get the tail end of the Grumeti crossings, the peak of the Mara crossings, excellent game viewing across every northern park Tarangire at its elephant-heavy best, Ngorongoro year-round reliable, Serengeti in full spectacle and reliable Zanzibar weather if you extend to the coast. The trade-offs are the cost and the crowds, both of which are manageable when the booking is made far enough in advance with the right camps in the right zones.

If budget is a significant factor, September into early October offers the same conditions with prices that are beginning to ease from their August peak and crowds that are noticeably lower in the second half of September as northern hemisphere summer holidays end.

If January to February is your available window, do not hesitate. The calving season at Ndutu is one of the most extraordinary wildlife experiences Tanzania offers — it is simply less famous than the Mara River crossings, not less significant. Fewer vehicles, lower prices, extraordinary predator activity, and a Zanzibar that is in excellent condition. January to February is a stronger month than its reputation suggests, and Rift & Ridge Safaris regularly places guests in this window who leave describing it as the best trip they have ever taken.

Tell us your travel window and we’ll show you exactly what you would experience and why it might be the best time to go for what you are after.
