The Udzungwa Mountains are called the Galápagos of Africa for good reason. This red colobus lives only here, in the same forests as the Sanje mangabey, a monkey that science only described in 1979.
Walks on the Sanje Falls trail usually find troops feeding in the lower forest, with the roar of the waterfall below. It is one of the great primate encounters in Tanzania and almost nobody knows about it.
