The Loma Mountains constitute the highest mountain range in Sierra Leone, situated in the northeastern part of the country near the border with Guinea. The range is dominated by Mount Bintumani, also known as Loma Mansa, which reaches an elevation of 1,945 meters above sea level, making it the highest peak in West Africa outside of the Cameroon Line and the Atlas Mountains. Geologically, the mountains are composed of ancient granitic rocks that have undergone weathering over millions of years. The slopes are characterized by a transition of ecosystems, starting with dense lowland rainforests that give way to montane forests and eventually sub-alpine grasslands at the highest altitudes. This environmental diversity supports numerous rare species, including the Sierra Leone Prinia and several endangered primate species like the western chimpanzee. The Loma Mountains were first established as a non-hunting forest reserve in 1952, covering an area of approximately 33,200 hectares. Due to its isolation and rugged terrain, the area remains one of the most significant wilderness regions in West Africa, providing essential watershed functions for the region's river systems.
