“Local legend says a giant serpent dwells in this hidden emerald crater lake, and that the water changes colour with the spirit's moods.”
About Ngozi Crater Lake
Ngozi lies in the volcanic Poroto Mountains of the southern highlands, a crater lake formed by past eruptions and now ringed by protected montane rainforest. Long wrapped in local legends of a resident serpent or spirit, the lake has remained a place of both natural beauty and traditional reverence, its forest home to highland birds and other wildlife.

Ngozi Crater Lake
Ngozi Crater Lake is a deep, emerald-green lake cradled in a volcanic crater in the Poroto Mountains of Tanzania's southern highlands, surrounded by dense montane rainforest. Reached by a hike through the forest, the lake sits hidden within its steep crater walls, its colour shifting and its calm surface wrapped in local legend.

The Lake of the Serpent
Ngozi is full of folklore. Local legend tells of a giant serpent or spirit said to dwell in the lake, and people have long regarded its deep green waters with awe and caution. The lake is also said to change colour, which traditional belief connects to the spirit's moods. The surrounding rainforest is rich in wildlife, including the striking Livingstone's turaco, a bird whose call rings through the trees on the climb up to the crater rim.
The Experience
You hike up through cool, dripping rainforest, often hearing the call of Livingstone's turaco, to reach the crater rim and look down on the deep green lake far below. The steep walls, the brooding water and the forest give the place a mysterious, slightly otherworldly feel that the serpent legends only deepen. The hike and the viewpoint are the heart of the experience.
Why It Matters
Ngozi Crater Lake is one of the scenic highlights of the southern highlands and a place where natural drama and local folklore meet. Its protected rainforest and birdlife add ecological value, while the serpent legend ties the lake to the spiritual landscape of the region's communities.
