Ngorongoro Crater in Tanzania is one of Africa’s top safari destinations and among the very best places to see the Big Five in a single day. Formed over 2.5 million years ago after the collapse of a massive volcano, this vast caldera is the largest intact and unbroken crater in the world. Its fertile floor, fed by rich volcanic soil, permanent water sources, open grasslands, acacia woodlands, and seasonal swamps, supports an extraordinary concentration of wildlife over 25,000 animals live within the crater year-round. Visitors can expect to encounter large prides of lions, massive bull elephants with impressive tusks, huge herds of buffalo, elusive leopards, and one of the highest densities of endangered black rhinos in East Africa.
