Udzungwa Mountains National Park

The Udzungwa Mountains are almost unearthly. An enchanted forest of leafy glades, freckled with sunshine where fungus, lichens, moss and fern ingratiate themselves into every damp crevice, it is at once both vivid detail and larger than life. A new variety of African violet was discovered in the shelter of 30m high trees. It's a hot house nurturing species found nowhere else on earth, a secret bank account of precious genetic stock. Its six types of primate, two are endemic-the Iringa red colobus monkey and the Sanje-crested- mangabey, not discovered until 1979s.

Four previously unknown birds, including the rufous-winged sunbird and a new species of the partridge-like francolin, make the Tanzania's richest forest birds habitat and among the three most important bird conservation areas on the continent. One of the east Africa's great forests, this undisturbed habitat undoubtedly has new treasures yet to reveal.

A link in the chain of Africa's eastern Arc Mountains, Udzungwa is made of hiking and climbing on trails through the rainforests and along the escarpments. The plateau is a natural tower top, with view of sugar plantations against a patchwork of grassland and mountain forest extending over 100 km. but the centerpiece is the sanje River which reinvents itself into a spectacular waterfall, plunging 170m through the forest to land in a mist in the valley below. Visit Udzungwa year around, but be prepared for rain anytime.
