Montagne d'Argent, Mountain in northeastern French Guiana
This summit rises 132 meters above sea level and overlooks the Oyapock River estuary near Pointe Béhague. The site covers roughly 7 square kilometers and is now protected by the Conservatoire du littoral.
In 1852 the first agricultural penal settlement was established here, built on what had been a coffee plantation. This prison camp remained active until 1910 and shaped the place's past.
Rock carvings found here show that indigenous peoples lived in this area long before European arrival. These ancient marks remain visible today and tell the story of the earliest inhabitants of this coastal region.
Access to this area requires prior authorization from the managing conservation authority. Visitors should contact relevant officials in advance to arrange permission for any visit.
Its position at the river mouth makes this an excellent spot for observing the region's wildlife. From here you can see the entire Oyapock estuary and watch the local animals that live along the waterway.
