Southern Serengeti Migration Guide

The southern chapter of the loop

The Great Migration is a year-round clockwise loop through the Serengeti–Mara ecosystem, not a single scheduled event — the roughly 1.5 million wildebeest, joined by hundreds of thousands of zebra, are always somewhere. The southern plains are where that loop pauses and turns: this is the calving country, the place the herds gather in the green months to give birth before beginning their long march north and west. If the Mara crossings are the migration's most famous chapter, calving on the southern plains is its origin story.

Understanding the south's role is the key to planning around it. The herds come here for the grass: the southern short-grass plains, blanketed in mineral-rich volcanic ash from the Ngorongoro highlands, are the best grazing in the ecosystem and the ideal nursery. They arrive with the short rains, calve in the heart of the wet season, and leave as the plains dry. Time your visit to that window and you stand inside one of the great wildlife events on earth; miss it, and the south is a beautiful but largely empty plain.

This page is about the migration specifically — when the south makes sense, what it offers and how to plan a trip around the herds. For the landscape and the wider experience of the southern plains in any season, see the southern plains guide.

When the herds are in the south

In a normal year, the migration is on the southern plains from around December to March. The short rains, breaking from around November, green the southern grass and pull the herds down from the central and western Serengeti. Through December and January they spread across the plains around the Ndutu area to graze, building condition for the births to come. The peak — the reason so many travellers target these months — is calving, which usually centres on February.

From around March and into the long rains of April and May, the picture begins to change. The herds calve, the calves grow strong enough to travel, and as the southern plains start to dry the great mass begins to move north and west in search of fresh grazing — towards the Western Corridor and the Grumeti, and eventually the far north and the Mara. By the dry season, roughly June to October, the south is largely empty of the migration, which is then in the centre, west or north.

Every one of those windows is a long-term average, not a promise. The migration follows the rains, and the rains vary: an early or late, strong or weak wet season shifts the timing by weeks and moves the herds with it. No chart, including this one, can tell you exactly where the herds will be on a given future date. The practical rule is to plan for the south in the green months, build in a few days' flexibility, and verify the likely picture for your specific dates close to travel.

• December–January: herds gather on the southern plains as the short rains green the grass.
• Around February: peak calving — the densest concentration the south ever holds.
• March–May: calves strengthen; the herds begin moving north and west as the plains dry.
• June–October: the migration has left the south for the centre, west and north.

Calving, not crossings: a different kind of drama

It is worth being clear about what the southern migration is — and is not. This is the calving chapter, not the river-crossing chapter. There are no Mara River crossings in the south; the crocodile-dark water and the churning gambles on the banks belong to the far north around Kogatende, in the dry season. The drama here is of a different order: the sheer scale of birth, with somewhere near half a million calves arriving in a window of about three weeks, and the relentless predator pressure that follows them.

That predator pressure is the south's signature. The open, treeless plains give the herds early warning and let cheetahs hunt in the clear, while lions and hyenas work the edges of the calving grounds. Calving season is statistically the most intense predator viewing of the Serengeti year — the single best window to watch a cheetah run down prey across open ground. For travellers torn between the south and the north, the choice is really between two spectacles: newborn life and big-cat hunting in the green-season south, or the river gauntlet in the dry-season north.

• Southern migration = calving and open-plains predators; no river crossings.
• River crossings belong to the far north (Kogatende), in the dry season.
• Calving brings the year's most concentrated big-cat action.
• Open ground makes the south the best place to watch cheetahs hunt.

Planning a southern migration safari

Because the herds are here only seasonally, the natural way to be close to the southern migration is a mobile or seasonal camp that sets up on the plains for the green months and moves with the action. These tented camps position themselves near the calving grounds during the peak window and shift as the herds do, putting you closer to the day's wildlife than any fixed lodge could. For a calving-season trip, a well-placed mobile camp is the classic choice, and the Ndutu area is the established base for it.

Ndutu sits at the heart of the calving grounds, on the southern edge of the ecosystem where the Serengeti meets the Ngorongoro Conservation Area. That location is a planning advantage in two ways: it is right where the herds calve, and it combines naturally with the Ngorongoro Crater, which lies on the route in from Arusha. A green-season itinerary might pair the Crater with several Ndutu-area nights for the calving and the open-plains predators. Note that part of the Ndutu area lies within the Ngorongoro Conservation Area rather than Serengeti National Park, which carries its own rules and fees — verify the detail when planning.

Two honest caveats close the plan. First, the migration cannot be scheduled or guaranteed — give yourself several nights in the south during the window and travel with a patient guide rather than chasing a single day. Second, rates and park and conservation fees change, so do not anchor to fixed figures; verify current numbers with operators and official TANAPA and Ngorongoro sources close to travel. Plan for the green months, build in flexibility, and let the plains surprise you.
