About Western Corridor

The Western Corridor extends from the central Serengeti towards Lake Victoria, following the Grumeti River through a landscape of dense riverine forest and open grassland. The migration passes through from May to July, with river crossings at the Grumeti that rival the more famous Mara crossings but with far fewer vehicles.

The Grumeti River is home to some of the largest Nile crocodiles in Africa, making the crossings particularly dramatic. The riverine forests support black-and-white colobus monkeys and a diversity of birdlife not found in the open plains. Several ultra-luxury camps in the Grumeti Reserves offer exclusive game viewing in private concession areas.
