Udzungwa Mountains National Park

The Udzungwas are the largest block of the Eastern Arc mountains, forested ranges in southern Tanzania so old and isolated that they hold species found nowhere else: the Iringa red colobus, the Sanje mangabey, and a long list of endemic birds. There are no roads inside the park; it is a hiking park, with the Sanje waterfall walk as the classic day and longer routes onto the plateau. It is reached by road from Mikumi, an hour away, and pairs naturally with that park. The dry season from June to October is easiest underfoot, and it is a malaria area at lower altitude.
