The Masai Mara National Reserve, in southwestern Kenya, is the country's best-known safari destination and the annual stage for the Great Migration's dramatic Mara River crossings, typically between July and October. Named for the Maasai people who still graze cattle along its borders, the reserve sits directly north of Tanzania's Serengeti, with which it shares an unfenced ecosystem.

What sets the Masai Mara apart
While the Great Migration moves between the Serengeti and the Mara throughout the year, it's the Mara's July–October window — when over a million wildebeest and zebra cross the Mara River in search of fresh grazing — that draws the reserve's peak visitor numbers and its highest lodge rates. Outside migration season, the Mara remains one of Africa's most reliable Big Five destinations year-round, with resident lion prides, leopard, and a healthy black rhino population in the reserve's conservancies.
The surrounding private conservancies, leased directly from Maasai landowners, offer lower vehicle density and activities like night drives and walking safaris that aren't permitted inside the reserve itself — a meaningful consideration when choosing a lodge.
