Guinea
Guinea lies to Sierra Leone’s north and east, sharing roughly 652 km of rugged border across forest and highlands. Several official crossings support trade and family ties; the boundary reflects colonial-era agreements and shared ethnic groups along the frontier.
Liberia
Liberia borders Sierra Leone to the south and southeast for about 306 km, with crossings such as Bo Waterside facilitating trade and refugee movements during past conflicts. The border follows rivers in places and connects similarly forested regions with historical ties through the Mano River basin.
