An idea for your trip: Guadeloupe - French Guiana

Second idea: Guadeloupe - French Guiana - Brazil

For travelers who wish to spice up their trip to the French Antilles, including Guadeloupe and Martinique, is more an opportunity to make a triangular trip,

for example Paris - French Guiana - Guadeloupe - Paris,

or even complementary to an incursion in Belem Brazil since French Guiana (the link between the TAF French Guiana-Cayenne and Belem is very easy).
