Lake Eyasi is a seasonal shallow endorheic salt lake on the floor of the Great Rift Valley at the base of the Serengeti Plateau, just south of the Serengeti National Park and immediately southwest of the Ngorongoro Crater in the Crater Highlands of Tanzania. The lake is elongated, orientated southwest to northeast, and lies in the Eyasi-Weber branch of the Great Rift Valley

The Hadzabe bushmen live in this region, as do the Datooga and Mbulu tribes. A visit with the bushmen is worthwhile and they will graciously show you where and how they live and hunt. They subsist entirely off the bush and by bow hunting. Everything they use is made from local materials, including their bows which are strung with giraffe tendon and their arrows which are coated in lethal poison. Their language resembles that of Kalahari bushmen tribe with clicking noises used.

The Datooga and Mbulu people are pastoralists, like the Maasai people.

The scenery of Lake Eyasi differs dramatically to that of the surrounding areas. Compared to the Serengeti and Ngorongoro Highlands this area seems downright tropical. Palm trees border the lake and make homes for birds such as Fischer’s lovebird. Other trees in this area include the umbrella thorn acacia and sandpaper bush. The weather is always hot and intense, as the lake is in floor of the Rift Valley, the oldest rift in the world. The rift is thought to have opened over 65 million years ago.

Lake Eyasi’s water levels vary between the rainy and dry seasons. During the dry season the lake is virtually non-existent, and animals are forced to share what water is left, which makes for easier wildlife viewing. The lake can get quite deep during the rainy season, and it attracts hippos who like to cool off in its brackish waters.

Bird lovers will be in paradise here, as the lake attracts vast numbers of birds of all sizes and colours. Some main birds to be found here include Africa spoonbill, flamingos, Gray headed gulls, great white pelicans, pied avocet, and yellow-billed storks. The main fish found in the lake are catfish and lungfish.

Lake Eyasi region is particularly suited for exploring on foot, and day or half day hikes are highly recommended. It is also possible to go on a hunting trip with the Hadzabe or to visit the other tribes.
