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-Wembere branch of the Great Rift Valley.
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 sand paper bush. The weather is nearly always very hot and intense, as the lake is located in floor of the Rift Valley, the oldest rift in the world. The rift is thought to have opened over 65 million years ago, shortly after dinosaurs became extinct.
Lake Eyasi’s water levels vary greatly between the rainy and dry seasons. During the dry season the lake is virtually nonexistent 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 colors. 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.
The Lake Eysai palm trees that sunset this region are 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 visit the Datoga tribes while in this area. Almost any time of year is a good time to visit Lake Eyasi with only April and May being questionable as they are when the long rains occur.
