Part of an ancient group of mountain ranges which stretch across Tanzania and Kenya, known as ‘The Eastern Arc’, the Udzungwa are the most extensive mountain range in Tanzania. They were formed at least 100 million years ago and many endemic species have evolved here, making them something of ‘an African Galapagos’. Local taboos have helped to preserve the wildlife, and now this national park protects almost 20% of the Udzungwa Mountains.

Among the bigger attractions are 10 species of primate, three of which are endemic: the Uhehe (aka Iringa) red colobus, the Matunda galago and the Sanje crested mangabey. The last of these is amongst the world’s 25 most threatened primates. With a day to explore slowly, you’ll usually see the red colobus along with the black and white Angola colobus besides the Blue and Vervet monkeys as well as yellow Baboons which are also common.
