About
The Grumeti River runs through the western corridor of Serengeti National Park in Tanzania. It is one of the park's most distinctive stretches of water, known to visitors as the Grumeti River Crossing or the Western Corridor. The river sits in the Mara Region, and its address is given simply as Grumeti River, Western Serengeti National Park.
What to expect at the river
The Grumeti is best known for its large Nile crocodiles, which can be seen resting on the banks and sandbars. The river is also a landmark of the great wildebeest migration. Between May and July, herds gather at the crossing points, and the moment they enter the water is one of the most watched events in the park. Visitors who time their trip for these months have the best chance of seeing it.
The surrounding landscape
Beyond the open plains, the river is lined with lush riverine forest, a green band that contrasts with the grasslands around it. This forest is home to colobus monkeys, which are often easy to spot in the trees along the water. The mix of forest, river and open grassland gives the western corridor a varied feel, with different wildlife in each setting.
Planning a visit
- Plan for May to July if you want to see the wildebeest crossings.
- Bring patience: animal sightings depend on the season and the movement of the herds.
- Look along the riverbanks for crocodiles and in the forest edges for colobus monkeys.
For travellers who want both dramatic wildlife and a quieter, greener side of the Serengeti, the Grumeti River offers a rewarding stop in the western part of the park.
