Visit Lake Eyasi and the Hadzabe tribe. A day trip to Lake Eyasi and the Hadzabe people who live there is very interesting. Lake Eyasi is a small salt lake that forms in the summer south of the Ngorongoro Highlands. It is a birdwatcher’s dream. First, look for hippos in the shallow water. Then, get your glasses and look for birds like the African spoonbill, flamingos, gray-headed gulls, great white pelicans, and pied avocets. Then go see the Hadzabe bushmen, who are experts at hunting with bows.
