The Udzungwa Mountains are a biodiverse and ecologically significant mountain range in south-central Tanzania. As part of the Eastern Arc Mountains, they are often referred to as the "Galápagos of Africa" due to their high levels of endemism and rich biodiversity. The Udzungwa Mountains National Park, which protects much of this region, is a prime destination for ecotourism, hiking, and wildlife research.

Geography and Location

The Udzungwa Mountains are located in the Morogoro and Iringa regions of Tanzania, covering approximately 1,990 square kilometers. The range extends from the Kilombero Valley in the east to the Great Ruaha River in the west, forming part of the larger Eastern Arc chain. The mountains feature steep ridges, deep valleys, and plateaus, with elevations ranging from 250 meters to over 2,500 meters at the highest peak, Luhombero Peak (2,579 meters).

Climate

The Udzungwa Mountains experience a tropical climate with high humidity and significant rainfall, particularly between November and May. The dry season, from June to October, offers the best conditions for hiking and wildlife viewing. Due to their elevation and forest cover, the mountains have a cool and misty environment, which supports a diverse range of flora and fauna.
