The Usambara Mountains rise steeply from the plains of north-eastern Tanzania, part of the ancient Eastern Arc chain and among the most biologically important forests in Africa.
The range splits into West and East Usambara, with Lushoto the main town in the west and Amani the centre of the eastern block. Altitudes run from around 200 metres at the base to over 2,200 metres on the highest ridges.
These forests have persisted continuously for tens of millions of years, and the resulting endemism is extraordinary. Hundreds of plant species occur here and nowhere else, and the African violet was first collected in these hills.
For visitors the Usambaras are walking country rather than safari country. Village-to-village hikes through farmland and forest, viewpoints over the Maasai plains far below, and a cool climate that makes a striking change from the coast are the draw.
