Sankan Biriwa Peak, reaching an elevation of 1,853 meters, is the second highest summit in Sierra Leone and forms the core of the Tingi Hills in the northeast of the country. The mountain massif was designated as a forest reserve in 1947 and covers an area of approximately 118 square kilometers. Geologically, the mountain is part of the Guinea Highlands and consists primarily of granite intrusions. The vegetation changes dramatically with altitude, transitioning from dense rainforest at the base to montane forests and subalpine grasslands on the summits. This vertical zonation supports a unique array of flora and fauna, including rare orchid species and endemic amphibians. Sankan Biriwa also holds great cultural significance for local communities and is revered as a sacred site in many traditions.

📋 Practical info
Getting there
Access to the Tingi Hills usually begins from nearby provincial towns, requiring a long drive on unpaved roads followed by a significant hike just to reach the base of the massif.
Best season
Climbing is best attempted purely during the dry season to avoid the treacherous, muddy trails and obscured visibility that characterize the extremely heavy West African monsoon.
Terrain & paths
The ascent involves first navigating through dense foothill vegetation, progressing onto steep, rocky inclines and exposed ridges as you gradually approach the second-highest summit.
What to bring
High-quality hiking boots, layered clothing for changing altitudes, ample water supplies, and highly reliable navigation tools are completely essential for this challenging trek.
Parking
Vehicles must typically be left in the last accessible village at the deep foothills, where informal local arrangements can often be made for secure overnight parking.
Safety
The extreme remoteness and rugged terrain mean that actively hiring a local guide who knows the paths is entirely vital for safety, as formal rescue services are virtually nonexistent.
Time needed
Conquering this prominent peak is typically a physically demanding multi-day expedition, realistically requiring at least two to three days for a safe ascent and subsequent descent.
