Togo is one of the smallest countries in Africa. The Togo Mountains bisect the country from southwest to northeast. To the east and south of the Togo Mountains, there is a sloping plateau covered with tall grass and trees. The coastal plain has swamps, lagoons, and palm forests. North of the Togo Mountains is a grassy plateau that gradually declines. The rainy seasons in the south occur from March to July and September to November; in the north, there is one long rainy season from April to October.
