Located on the west coast of Africa, The Gambia is bordered by Senegal in the north, east and south and by the Atlantic Ocean on the west.
The Gambia River, the country's major waterway, rises in the Futa Jallon in Guinea and follows a twisting path for 1,000 miles to the sea. In its last 300 miles, the river flows through the Gambia, narrowing to a width of 3 miles at Banjul. Mangrove swamps line both sides of the river for the first 100 miles from the sea; the mangroves then give way to more open country and, in places, the red ironstone cliffs. The land on either side of the river is generally open savanna with wooded areas along the drainage channels.
