They are two halves of one ecosystem. Tanzania’s Serengeti is roughly ten times larger and hosts the Great Migration for most of the year, including the calving season. Kenya’s Maasai Mara is compact, easy to reach from Nairobi and holds the herds from roughly July to October, with private conservancies that limit vehicles. Your travel month usually decides.

The verdict: Book the Serengeti for the calving season, a longer trip or a classic northern Tanzania circuit. Book the Maasai Mara for a shorter safari, peak river crossings from a conservancy camp, or an easy add-on to Nairobi. From July to October, both deliver the migration.
Choose the Serengeti if…
…you’re traveling outside July to October, or you want the full sweep of the migration. From roughly January to March, the herds calve on the short-grass plains of the southern Serengeti and Ndutu, drawing lions, cheetahs and hyenas. By June they push west toward the Grumeti River, and by July they reach the Mara River in the north. Our Great Migration guide maps the year.
Scale is the other draw. The Serengeti is vast, so camps can feel remote even in high season, and mobile camps relocate to follow the herds. It also fits neatly with Ngorongoro Crater and Tarangire on Tanzania’s northern circuit, with a beach finish on Zanzibar.
Choose the Maasai Mara if…
…your dates fall between July and October and your time is short. The Maasai Mara is under an hour by light aircraft from Nairobi’s Wilson Airport, so a night in Nairobi is often all that separates your long-haul arrival from your first game drive. Resident lions, leopards and cheetahs make it rewarding year-round, not only during the migration.
The private conservancies bordering the reserve, such as Mara North, Olare Motorogi and Naboisho, are what set the Mara apart: limited beds, capped vehicle numbers, off-road driving, night drives and walks. Stay in a conservancy and drive into the reserve for crossings, and you get the best of both.
Can you do both the Serengeti and the Maasai Mara?
Yes, though not by driving across. Safari vehicles can’t cross the border between the two parks, so combined trips connect by air through Nairobi and Kilimanjaro or Arusha, which takes most of a day. It works best on an itinerary of 10–12 nights or more.
A popular plan is three nights in a Mara conservancy, then Ngorongoro and the Serengeti, ending on Zanzibar. Our Kenya vs. Tanzania comparison looks at the wider country choice.
