The Migration Is Not a Single Event You Book a Ticket For

Around 1.5 million wildebeest move continuously through the Serengeti-Mara ecosystem across Tanzania and Kenya throughout the year, following rainfall and grass. This is not a scheduled performance. The famous Mara River crossings, where herds plunge into crocodile-filled water on the Kenyan border, happen unpredictably between July and October. A herd may arrive at a crossing point and turn back dozens of times before committing. Safari operators who promise you will “see the crossing” are making a claim the wildebeest have not agreed to. The honest operators will tell you when and where probability is highest, then manage your expectations accordingly.

The Seasonal Calendar

January through March is calving season on the southern Serengeti plains around Ndutu. Around 500,000 wildebeest calves are born within a compressed six-week window, which is also when cheetah and lion concentrations in the area peak. The predator-prey dynamic during calving season is arguably more dramatic viewing than the river crossings, and significantly less crowded.

April through June, the herds move through the central Serengeti and into the Western Corridor toward the Grumeti River, which has its own crocodile population and produces crossings on a smaller but still striking scale.

July through October is the peak season for the Mara River crossings in the northern Serengeti, near Kogatende and the Lamai area. August is the most statistically consistent month for crossings, though “consistent” is relative. November sees the herds beginning the return south.

The entire cycle is rain-dependent. An early rainy season can shift all of the above by several weeks.

Park Entry Fees

Non-resident adults pay 83 US dollars per person per 24-hour period to enter Serengeti National Park in 2025 and 2026. Children aged 5 to 15 pay 24 dollars; children under 5 enter free. East African Community citizens pay a significantly lower rate. Fees are payable in cash USD or Tanzanian shillings at the entry gates. Game drives are permitted only between 6am and 6pm. Some gates, including Ndabaka and Klein’s Gate, do not permit entry after 4pm.

Getting There

The international gateway is Kilimanjaro International Airport (JRO), located between Moshi and Arusha, served by airlines including KLM, Ethiopian, and Precision Air via their hub connections. From JRO, the most common route into the park for those on organised safari packages is a connecting flight to one of seven airstrips inside the Serengeti. A one-way Arusha to Seronera flight runs around 265 US dollars per person through Coastal Aviation and similar operators, and takes around 45 minutes to 1.5 hours depending on the airstrip. Flying in means you cross directly into the ecosystem rather than spending a day on the 8-hour road from Arusha.

Drive-in safaris from Arusha typically include an overnight stop in the Ngorongoro Conservation Area en route, which adds the Ngorongoro Crater to the itinerary. The crater floor, a collapsed volcanic caldera, supports one of the highest densities of large mammals in Africa and is worth visiting in its own right.

Where to Stay

Accommodation inside the park or in the private concessions adjoining it ranges from genuinely expensive to remarkably expensive. Mid-range tented camps such as Lemala Ewanjan or Kubu Kubu run from 350 to 750 US dollars per person per night, typically including all meals and game drives. Luxury properties like Singita Sasakwa and Asilia Sayari Camp in the northern Serengeti run from 1,000 to 1,500 dollars per person per night at peak season.

The distinction between a tented camp and a lodge in the Serengeti is primarily one of atmosphere rather than comfort level. The better tented camps are extraordinarily comfortable and sometimes have better wildlife access than permanent lodge structures because they move with the migration. Asilia Sayari in the north is particularly well-positioned for July-to-October Mara River access.

For calving season in the south, camps around Ndutu, which sits in the Ngorongoro Conservation Area adjacent to the southern Serengeti, provide the best positioning from January through March.

Activities

Game drives are the primary activity. Most camps run a morning drive from sunrise until mid-morning and an afternoon drive from around 4pm until dusk. A full day drive with a packed lunch allows access to distant areas in the time it takes a half-day to reach them. This is particularly relevant in a park the size of Serengeti (14,750 square kilometres).

Walking safaris with armed rangers are permitted in some areas and provide a completely different sense of the landscape. What looks flat from a vehicle reveals drainage lines, termite mounds, and animal tracks that are invisible from car height. They also require considerably more nerve than sitting in a Land Cruiser.

Hot air balloon flights, operated by Serengeti Balloon Safaris among others, depart at dawn and drift over the plains for approximately an hour. They cost around 500 to 600 US dollars per person and include a champagne breakfast on landing. The experience of watching the landscape from above in early light is not something a ground-level game drive replicates.

Stargazing is a genuine feature of the Serengeti rather than a tourism gimmick. Light pollution is near zero in most of the park. On a clear night at a camp without generator noise, the Milky Way is fully visible to the naked eye.

Practical Notes

Tanzania does not have year-round optimal weather in the Serengeti. The long rains in April and May turn some tracks impassable and many operators close seasonal camps during this period. The short rains in November are lighter and less disruptive. Green season (the rainy periods) sees drastically lower prices, fewer tourists, and lush landscapes, but some camps close and some roads become difficult.

Malaria prophylaxis is necessary. Yellow fever vaccination is required if you are arriving from a country with yellow fever transmission. A valid passport and Tanzania e-visa (applied online before travel) are needed at the gate.

The single most practical piece of advice for first-time visitors: book the northern Serengeti for river crossings, the southern plains for calving, and allow at least three full days of game drives regardless of where you are. The Serengeti rewards patience in a way that rushed itineraries cannot access.
