Hippos spend the day in water and the night grazing, walking many kilometres from the river. In the Serengeti the Retina hippo pool and the Grumeti River hold big groups, and the Ngorongoro Crater’s Ngoitokitok picnic site has its own resident pod.
In Ruaha the Great Ruaha River shrinks in the dry season and the hippos crowd into the remaining pools, which makes for noisy, dramatic viewing from the bank.
