Sierra Leone is a country situated on the west coast of Africa, with a topography characterised by mountain ranges, hills, and river valleys.
The majority of the country is made up of plateaus with elevations varying from 500 to 1500 feet above sea level, with the highest altitude at Loma Mansa (6,390 ft) in the Loma Mountains.
The topography is highly undulating with a narrow coastal plain stretching for about 250 kilometers parallel to the Atlantic Ocean.
Sierra Leone is a nation of contrasts, where the topography in some areas is rugged and difficult to access while other regions are relatively flat and amenable to cultivation.
The highest point in Sierra Leone is Loma Mansa, which is part of the Loma Mountains and stands at an elevation of 6,390 feet above sea level.
The lowest point in Sierra Leone is the Atlantic Ocean, which borders the country along its western coast at sea level.
