The Poroto Mountains are a volcanic range situated in the Southern Highlands of Tanzania, southeast of the city of Mbeya. This range is part of the Rungwe Volcanic Province and is characterized by a series of extinct volcanic cones and lush forest reserves. One of the most striking features of the Poroto Mountains is the Ngosi Crater Lake, a deep, emerald-green lake contained within a massive volcanic caldera at an elevation of 2,260 meters. The mountains receive high levels of precipitation, fostering the growth of dense evergreen forests that are home to rare bird species and primates. The fertile volcanic soil supports intensive agriculture, particularly the cultivation of potatoes and pyrethrum by the local communities. Due to their elevation and moisture, the Poroto Mountains play a crucial role as a catchment area for the region's rivers, contributing to the water supply of both Lake Malawi and the Ruaha River system.
