Catching The Great Migration as it crosses the Grumeti River near the Western Corridor's Kirawira region is a must for avid nature lovers, although those with weaker stomachs may want to steer clear. This particular section of the river is known for its large crocodile population; the crocs anxiously await the migrating herd's crossing for a guaranteed meaty feast. Yet despite the obvious danger, the wildebeest and zebras will stop at nothing to reach their final destination. Other animals you'll find swimming in the river and drinking from its water include elephants, hippos and monkeys.

To see The Great Migration from this part of the Serengeti, visit between July and November. Also, recent travelers recommend bringing a boxed lunch to enjoy picnic-style near the river.

The Grumeti River snakes through the Western Corridor to the west of the Seronera River Valley. Getting to the area will require driving, taking a safari tour or flying into the Grumeti airstrip. Accommodations along the river's south bank are available at Kirawira Serena Camp. Picnic areas and a pedestrian suspension bridge are offered here, but no additional facilities are provided. The Grumeti River is free to visit 24 hours a day. Check out the park's website for more information about the river.
