Start with the event you want to see
For a Great Migration safari focused on calving, plan around the southern Serengeti and Ndutu–Kusini area in January–March, with February a common focus. For Mara River crossing opportunities, choose the northern Serengeti around Kogatende or Lamai, broadly July–October. If your dates are fixed, choose the camp location to match the likely seasonal area rather than booking the same lodge for any month.
The migration continues through the year. It is not one river crossing on a fixed date, and the herds do not move as a single tightly packed group. Rainfall and grazing affect their movements. No month, camp or length of stay guarantees a crossing, a birth or a predator encounter.

| Your decision | Start your search here | Planning implication |
|---|---|---|
| January–March | Southern plains, Ndutu and Kusini | Prioritise a southern camp for calving-season interest; February is a common focus |
| April–May | Southern-to-central movement, including the Moru area | Expect a shifting search area and rain-season camp closures; avoid a fixed-event promise |
| June | Western Corridor and the move north | Grumeti-area interest is different from booking for Mara River crossings |
| July–October | Northern Serengeti, Kogatende and Lamai | Give the northern area its own multi-night stay; exact timing varies |
| November–December | Return through central and eastern sectors towards the south | Select an operating camp for the actual dates; the herds can be spread widely |
Calving safari: southern plains, not the crater floor
TANAPA’s migration guidance places the short-grass calving plains between Naabi and the Ngorongoro highlands and describes the concentration of births around mid-February. This supports a southern-plains safari, not a promise that every day in February brings a birth in front of your vehicle.
Ndutu and Kusini are the useful names to resolve when choosing this trip. The migration ecosystem includes parts of the Ngorongoro Conservation Area, but the Ngorongoro Crater floor is a separate safari visit. A crater-rim booking does not put you beside the southern herds. Keep the actual southern camp location in the itinerary rather than using Ngorongoro as a vague overnight label.
TANAPA: calving geography and migration guidanceApril to June: the journey north and west
Asilia’s month-by-month guide describes movement through the central Serengeti and Moru area towards the Western Corridor and Grumeti, followed by the journey north. Treat this as a broad historical pattern. Its own calendar contains overlapping movements, which is one reason a month label cannot function as a precise wildlife location.
A central or western trip can suit travellers interested in the moving herds rather than a specific river scene. It also needs an operating camp and workable roads during or after the long rains. Sayari closes in April–May; Ubuntu closes from mid-March through May. Those two examples cannot be booked as if every migration camp operated year-round.
Asilia: historical month-by-month patternMara River season: stay in the north
Kogatende and Lamai are northern Serengeti airstrips listed by TANAPA. Camps in that area can make a northern migration stay practical without daily drives from central Seronera. Asilia’s Sayari page uses July–October as the broad migration season and explicitly says river crossings are not guaranteed.
Crossings can happen in different directions and the herds can gather without crossing. A safari consisting only of a brief drive to the river leaves little flexibility. As an editorial allocation, allow three or four nights in the northern sector if this is the main trip objective. More time gives you more opportunities to watch wildlife, not a mathematical guarantee. Include ordinary game drives rather than making every day depend on a crossing.
Sayari: northern season and crossing uncertaintyWhat responsible crossing viewing requires
TANAPA’s Mara River guidelines require vehicles to remain stationary in designated viewing areas when herds gather or cross. Drivers must respect crossing-point capacity and distance signs, leave animals space and avoid blocking their path. Visitors must remain in their vehicles except in emergencies; riverside picnic setups are not allowed.
A promise to rush up to the riverbank for an unobstructed close-up conflicts with that approach. Designated sites and temporary restrictions can limit where vehicles go, including during very wet conditions or when vegetation needs recovery. Accept those limits as part of the safari rather than judging a guide by whether they can force a front-row position.
Read TANAPA’s Mara River crossing guidelinesMobile camps move seasonally, not on demand
A seasonal camp can work well when its planned site matches the broad herd location. Ubuntu illustrates the model: Asilia currently lists a northern Lamai Wedge season from June to mid-November and a southern Kusini season from mid-December to mid-March, with closures between them. Your booking is for the site operating during your dates.
You do not travel inside the camp as it follows wildlife each day. Nor does a mobile camp guarantee that the herds remain close. A permanent northern camp can be just as geographically appropriate for the river season; the choice also depends on facilities, transfers and the kind of stay you want.
Ubuntu: published seasonal camp locationsChoose one coherent route before adding parks
For six safari nights with a migration focus, an editorial option is four nights in the seasonally appropriate Serengeti sector and two nights in another area that fits the transfers. Arrival and departure hotel nights are additional if they fall outside those six nights. A northern fly-in stay is a different journey from a road circuit through Tarangire and Ngorongoro.
Our seven-day Tanzania route uses three central Serengeti nights and deliberately does not promise northern crossings. If crossings are the priority, replace parts of that route and choose a northern arrival rather than inserting a river day into a central stay. In calving season, a southern base can be a more natural replacement on the northern road circuit.
See the seven-day route and where it needs adaptingSerengeti or Masai Mara for migration?
The herds use an ecosystem across Tanzania and Kenya. A northern Serengeti stay and a Masai Mara stay can both suit the broad northern migration season, but neither gives you unrestricted game-drive access across the international border. If booking both countries, the human travel itinerary needs its own transfers and formalities; it does not simply follow the animals.
For a shorter trip, choose the side that fits your arrival city, time and preferred accommodation arrangement. For southern calving-season interest, Tanzania’s southern plains are the relevant starting point rather than a Mara booking.
Compare Masai Mara and Serengeti safari choicesTurn the season into an actual camp choice
Resolve the sector, month-specific camp site and arrival strip before comparing room photographs. Then compare complete costs: accommodation, vehicle and guide, park and camp-related charges, flights and transfers. A cheaper camp far from the intended sector is not necessarily a cheaper version of the same safari.
The seasonal guide here is a planning aid, not a live herd tracker. Use it to choose the right broad geography and enough time in it, while keeping the daily wildlife plan flexible.
