With an area of 1,990 square kilometers the park is bordered to the eastern by Kilombero valley and Selous game reserve, Mikumi town to the north and the continuing Udzungwa Mountains to the south which makes the total range of 10,000 square kilometers.
The park is attractive for its waterfalls to the Mwanihama peak which can be climbed for three days. Hiking to Udzungwa requires a high level of fitness as it is a very steep climb.
The north western side has deciduous trees dominated by acacia while in eastern side of the park has evergreen moist forest of both lowland and montane forest.
