Salines de Montjoly is a former saltworks and protected area in the commune of Remire-Montjoly in French Guiana, France.

The beach is used by sea turtles for nesting,[4] the dune ridge contains desert vegetation,[3] the wetlands are a refuge for migratory birds, and it contains the only publicly accessible mangrove forest of French Guiana.

The presence of a fresh water wetland behind the beach is rare, and attracts migratory birds which include muscovy ducks and blue-winged teals.

Since then strong tides have caused damage to the area, and as of 2020, certain parts have been closed to the public pending restoration.

[4] Salines de Montjoly is located 10 kilometres (6.2 mi) from the capital Cayenne, and has a publicly accessible observation platform on the lagoon and several paths through the mangrove forests.
