Recommended Reading Environment Located on the northeastern coast of South America, French Guiana is roughly the same size as Ireland or the US state of Indiana.
Litani rivers encompass a disputed border area.
Most Guianais live along the Atlantic coast, and the area contains most of the country's limited road network. The coast comprises mainly mangrove swamp with a few sandy beaches. Fauna includes monkeys, caimans, tapirs, ocelots and anteaters. The rain falls heaviest from January to June, with May seeing the worst of it. Cayenne, the capital, and Guiana's other Atlantic coast settlements are less muggy than inland areas, but that's not saying much.
