Serengeti National Park

Roughly 1.5 million wildebeest and 250,000 zebra move in a broad clockwise loop through the ecosystem every year, and the calendar is well documented even if exact dates shift with the rains. Calving happens on the short-grass plains around Ndutu, January–March. The herds push north through the Western Corridor and cross the crocodile-filled Grumeti River around May–June, then reach the Mara River in the north for the famous crossings from July through September, spilling into Kenya's Masai Mara. October–November brings the return south.

Tanzania's dry season (June–October) is the classic safari window — minimal rain, thinner bush, and wildlife concentrated around remaining water sources. It's also the most expensive and heavily booked period, particularly August. The short rains (November–December) are brief afternoon showers that rarely disrupt game drives and come with lower rates. The long rains (March–May) are the true low season — some camps close, roads get muddy, but Ndutu's calving season falls right in the middle of it and the birdlife and landscape are extraordinary.

The operator matters more here than almost anywhere else you'll travel — a good guide radios other vehicles, reads animal behaviour, and knows which side of the river the herds are massing on; a mediocre one drives to the same three spots as everyone else. Ask prospective operators directly which camps they use during migration season and whether guides are shared or dedicated to your vehicle. Tented camps (canvas, but with proper beds, en-suite bathrooms and full board) are the norm at every price point — 'camping' does not mean roughing it once you're above budget tier.

There is no self-drive culture here — virtually everyone travels with a safari vehicle and driver-guide, either as part of a lodge package or a private tour. Distances are large and roads are unpaved, dusty corrugated tracks, so overland transfers between zones can take 4–6 hours; light aircraft between the ecosystem's airstrips cut that to 20–40 minutes and are worth the extra cost on multi-camp itineraries. Most trips start and end in Arusha, itself a 45–60 minute flight or 5–6 hour drive from the park.

Nearly all Serengeti accommodation is full-board, and the standard has risen sharply over the past decade — three-course bush dinners, decent South African and Chilean wine lists, and packed breakfasts for early game drives are now normal even at mid-range camps. Don't expect much local Tanzanian cuisine inside the park itself; it's mostly international safari-lodge fare, competently done. The better food experiences — ugali, nyama choma, pilau — are found in Arusha or on a Zanzibar extension afterward.
