Udzungwa Mountains National Park

Udzungwa Mountains National Park is Tanzania's premier hiking destination and one of Africa's most significant biodiversity hotspots. Located in the Southern Highlands of Tanzania, approximately 350 kilometres from Dar es Salaam, the Udzungwa Mountains form part of the Eastern Arc Mountains — an ancient chain of mountain blocks that have acted as an island of moist forest for millions of years, generating extraordinary levels of plant and animal endemism.

The Eastern Arc Mountains are considered one of the world's most important biodiversity centres, rivalling the Galapagos Islands and the Amazon Basin in terms of the proportion of endemic species relative to total area. The Udzungwa sector alone protects over 400 species of endemic or near-endemic plants, and several animal species found nowhere else on Earth.

The park's most famous residents are its endemic primates. The Sanje mangabey — a large, endangered monkey discovered by science in 1979 and found only in the Udzungwa Mountains — is one of Africa's rarest primates and can be observed in the forest around the park headquarters near Mang'ula. The Iringa red colobus, another endemic primate species unique to the Udzungwa ecosystem, is frequently encountered in troops along forest trails. These close encounters with critically rare primates, in a setting of extraordinary forest beauty, are among Tanzania's most genuinely exceptional wildlife experiences.

The park's trail network offers hiking experiences ranging from short nature walks to multi-day wilderness treks. The most popular route, the Sanje Waterfall Trail, follows a river through the forest to reach the spectacular Sanje Falls — a 170-metre waterfall that plunges through the forest canopy in a series of cascades. The hike to Sanje takes approximately four hours return and passes through several forest types, offering excellent primate and bird watching along the way.

The Mwanihana Peak Trail leads to the highest point in the park at 2,576 metres above sea level — a demanding multi-day trek through diverse forest zones from lowland tropical forest through montane forest to high-altitude grassland.

The birdlife of the Udzungwa Mountains is exceptional, with over 400 species recorded including 28 species endemic to the Eastern Arc Mountains. The Udzungwa partridge, Rufous-winged sunbird, and Nduk eagle owl are among the species that dedicated birders make special pilgrimages to observe.

Udzungwa is typically combined with a visit to Mikumi National Park — just 60 kilometres away — and together they form the core of an excellent southern Tanzania circuit that rewards travellers with authentic, crowd-free experiences.
