The dominant religion of French Guiana is Roman Catholicism; the Maroons and some Amerindian people maintain their own religions. The Hmong people are also mainly Catholic owing to the influence of missionaries who helped bring them to French Guiana.
The official currency is the Euro. French Guiana is the most expensive among all South American countries. Traveling to French Guiana’s interiors is expensive, so plan your trip. The budget traveler would find it hard to get by with less than US$55 a day.
