Short answer: the Serengeti is a year-round safari destination, but the single best time depends on which spectacle you want to witness. For the dramatic Mara River crossings, aim for July to October. For the calving season and its predator action, come in late January to February. Below is a month-by-month guide to help you plan around the largest land-mammal migration on Earth — over 1.5 million wildebeest moving in a single, restless loop.

Where the herds are, month by month

The migration is not an event with a fixed date — it is a continuous, rainfall-driven cycle. Timing shifts a few weeks each year, so treat every window below as a strong probability rather than a guarantee. Once you have chosen a season, our guide to where to stay in the Serengeti by season helps you match the right camp to the herds.

Month	Where the herds are	What's happening
Dec – Mar	Southern plains · Ndutu	Grazing the nutrient-rich short-grass plains
Jan – Feb	Ndutu calving grounds	Calving season peaks — and so do the predators
Apr – May	Central Serengeti · Seronera	Herds push north through the long rains
Jun – Jul	Western corridor · Grumeti River	First river crossings, with far fewer crowds
Jul – Oct	Northern Serengeti · Kogatende	The iconic Mara River crossings (peak in September)
Nov	Return south · eastern plains	Short rains draw the herds back down

Calving season: nature at its most intense

If you want raw wildlife drama, the calving season on the southern plains is hard to beat. Across a compressed two-to-three-week window in late January and February, roughly 500,000 calves are born — as many as 8,000 in a single day at the peak. That concentration of vulnerable young draws lions, cheetahs, and hyenas, making it one of the finest times of year for predator sightings.

The river crossings: the Serengeti's signature moment

From July through October, the herds mass on the banks of the Mara River in the far north. The crossings — thousands of animals plunging through crocodile-filled water — are what most people picture when they imagine the migration. September is widely considered the strongest month. Earlier in the season, the Grumeti River in the west offers a quieter, less-crowded alternative.

The Serengeti by the numbers

Part of what makes this ecosystem extraordinary is its sheer scale — a protected wilderness of 14,763 km², a UNESCO World Heritage Site since 1981, holding some of the densest wildlife populations in Africa.

Wildlife	Population (est.)
Wildebeest (migration herd)	1,500,000+
Plains zebra	250,000
Thomson's gazelle	400,000–500,000
Lions	3,000+
African bush elephants	5,000+
Eastern black rhino	fewer than 70
Bird species recorded	500+

What a Serengeti safari costs in 2026

Costs vary widely by style of travel. As a rough guide, here is what to budget per person, per day — typically covering a 4x4 vehicle, guide, park fees, meals, and accommodation. For a fuller breakdown of what to budget, see our 2026 Serengeti safari cost guide.

Style	Per person, per day
Budget (camping)	$250 – $400
Mid-range (lodges)	$450 – $800
Luxury	$850 – $1,500+

The Serengeti park entry fee alone runs $82.60 per adult, per day in 2026. A sunrise hot-air balloon safari — a bucket-list add-on — costs around $599 per person.

Travel that gives back

The migration is a survival story as much as a spectacle: an estimated 250,000 wildebeest die each year along the route from exhaustion, predation, and river crossings. With black rhino numbers below 70, the Serengeti's future depends on conservation-minded tourism. Choosing operators who reinvest in anti-poaching and community programs helps keep this wilderness wild for the herds — and for the travelers who come to witness them.
