Udzungwa is not a game-drive park. There is essentially one road; the park is explored on foot, which makes it the odd one out on this list and the reason ecologists rate it far above its visitor numbers.
It is the largest block of the Eastern Arc Mountains, a chain of ancient crystalline ranges sometimes called the Galápagos of Africa for the endemism the isolation has produced. Forest runs unbroken here from around 250 metres to over 2,500, which is rare anywhere, and species keep being described: the Udzungwa red colobus and the Sanje mangabey live nowhere else, and the grey-faced sengi — a forest elephant-shrew the size of a small rabbit — was new to science as recently as 2008.
The standard walk is to the Sanje Falls, a 170-metre cascade reached in a half-day climb through forest, with a swimming pool at the base and a view out over the sugar estates of the Kilombero valley. Longer routes run several days across the plateau.

Two or three days to the escarpment top, camping on the way.
Eastern Arc endemism
Plants and animals that exist here and in no other forest.
