Where Is the Maasai Mara?

The Maasai Mara sits in Kenya’s southwest, pressed against the Tanzania border where it flows seamlessly into the Serengeti. At 1,500-1,900m altitude, mornings are cold and misty. It’s 5-6 hours by road or 45 minutes by air from Nairobi, and home to millions of grazing animals during the August-October migration.

The Maasai Mara on Kenya’s Map

The Maasai Mara Reserve sits in Narok County, southwest Kenya, backing directly onto the Tanzania border. At 1,500-1,900 meters altitude, mornings can be cold and misty most of the year. The reserve is part of one vast Mara-Serengeti ecosystem spanning 25,000 km², but administratively it’s separate from Tanzania’s Serengeti National Park.

Location: Southwest Kenya, on the Border

The Maasai Mara lies in Narok County in Kenya’s southwest corner, nearly touching the Tanzania border. Nairobi sits 270km to the southeast – a 5-6 hour drive or 45-minute flight. The nearest large town is Narok, 130km away by road (2-2.5 hours from the Mara), the last good place for fuel and supplies before heading into the reserve. Lake Victoria and Kisumu lie roughly 250km northwest, 5-6 hours away via Bomet if you’re chaining reserves or heading toward Uganda.

Altitude and Climate: Mornings Are Cold

The reserve sits between 1,500 and 1,900 meters above sea level. This elevation means mornings, especially from June through August, can be cold and misty. Bring a fleece or warm jacket for early game drives. The air is thinner than at sea level but not high enough to cause altitude issues for most visitors. Nights stay cool year-round; days warm up by mid-morning once the sun clears the mist.

Part of the Greater Mara-Serengeti Ecosystem

Ecologically, the Maasai Mara and Tanzania’s Serengeti form one continuous ecosystem spanning roughly 25,000 km². Wildlife moves freely between them, especially during the annual wildebeest migration. But administratively and for tourism purposes, they’re separate: the Mara is Kenya’s reserve, the Serengeti is Tanzania’s national park. No tourist border crossing exists between them inside the parks. To move between the two, you either fly or drive out to an official border post like Isebania and re-enter the other country.

The Wildebeest Migration

The Mara’s most famous moment comes August through October, when millions of wildebeest, zebra, and antelope move north from the drying Serengeti into the Mara’s greener pastures. This is the ‘short rains’ season in the Serengeti; the Mara’s longer grass holds more animals for longer. The migration is nature’s largest land animal event and draws travelers worldwide. Outside these months, the Mara still holds substantial game and offers a more peaceful experience.

Understanding the Maasai Mara

How far is the Mara from Nairobi?

270km southwest, typically 5-6 hours by road (via Bomet or Narok towns). Alternatively, fly 45 minutes from Wilson or Nairobi’s international airport.

Is it cold in the Mara?

Mornings often are, especially June-August. Altitude is 1,500-1,900m, so pack layers. Midday warms up; nights stay cool.

Can I cross into Tanzania from the Mara?

Not through the parks directly. You’d drive or fly to an official border post like Isebania, exit Kenya, enter Tanzania, then transfer to the Serengeti. Most operators handle this, but it’s a separate entry process.

When does the wildebeest migration happen?

Typically August through October. The herds arrive from Tanzania’s Serengeti as the dry season pushes them north into the Mara’s green grass. It’s the year’s peak season and draws the most visitors.
