French Guiana (French: Guyane française, officially Guyane) is an overseas département (département d'outre-mer, or DOM) of France, located on the Caribbean coast of South America and part of Caribbean South America.
French Guiana consists of three main geographical regions: a coastal strip where the majority of the people live, then dense, near-inaccessible rainforest, which gradually rises to the modest peaks of the Tumac-Humac mountains along the Brazilian frontier.
The borders between French Guiana and those countries lie along the Maroni River in the rainforest, which are difficult to patrol for French Gendarmerie forces.
Guiana was the name given to all that region of South America which extends along the Atlantic coast from the Orinoco to the Amazon.
British Guiana is separated from Venezuela, partially by the Orinoco, and partly by a line drawn to the east of that river.
Guiana is the habitat of several dangerous species of wild beasts, including the jaguar, as well as of the anaconda and of the most deadly reptiles in the New World.
