The Republic of Guinea is located in West Africa and bounded by Guinea Bissau, Senegal, Mali, Cote dIvoire, Liberia and Sierra Leone.
The River Niger flows north from the southern highlands into Mali before turning south again through Niger and Nigeria.
The coastal plain is made up of mangrove swamps. In the northeast, savannah plains of the Sahel region stretch into Mali. To the south are mountains known as the Guinea Highlands.
