Ghana

Ghana is arranged from south to north in belts: the Atlantic coast with lagoons, mangroves and turtle nesting beaches; the rainforest of the southwest, an extension of the Upper Guinean block; the transition zone of the centre; and the Sudanian and Guinean savannahs of the north, where Mole park lies, the country's largest, with savannah elephants, buffalo, antelopes and baboons. Lake Volta, created by the Akosombo dam, is one of the largest reservoirs in the world by surface area and has transformed the ecology of the river. At Kakum, a suspended walkway allows the forest canopy to be crossed tens of metres above the ground, and the coastal lagoons of Keta and Songor are Ramsar sites with concentrations of terns and migratory waders.
