Travel guide
French Guiana is an overseas French department and region in the Amazonia region of South America, bordering the North Atlantic Ocean, between Brazil and Suriname. It is governed as an overseas department of France with the same rights and privileges granted to all other French departments, and it benefits financially from the arrangement. Compared to the other "Guianas", French Guiana has the most visible preserved rainforest and a more relaxed and organized lifestyle, but also the highest prices and the least backpacker infrastructure.
