The Îles du Salut—comprising Île Royale, Île Saint-Joseph, and Île du Diable—form one of the most historically charged archipelagoes in the Americas, rising from the Atlantic Ocean approximately 14 kilometres off the coast of Kourou in French Guiana. Their name, meaning Islands of Salvation, derives from the 18th century, when early colonists found the islands' sea breezes a refuge from the malaria-ridden mainland. The islands became synonymous with incarceration when France incorporated them into the bagne penal colony system, beginning formal use as a detention site around 1852. Île Royale served as the main administrative hub, housing prison staff, a hospital, and the bulk of the convict population in stone barracks that still stand today. Île Saint-Joseph held the notorious réclusion solitary confinement cells—windowless stone chambers where the most troublesome prisoners endured years of enforced silence, communicating only by a clandestine tap code. Île du Diable, the smallest and most isolated, was reserved primarily for political prisoners and remains off-limits to visitors today.
The islands achieved international notoriety through the Dreyfus Affair: French army captain Alfred Dreyfus, falsely accused of treason on the basis of forged evidence and anti-Semitic prejudice, was imprisoned on Île du Diable from 1895 to 1899 before his eventual exoneration. His stone hut and the ruins of his enclosure are visible across the narrow channel from Île Royale. Henri Charrière's 1969 memoir Papillon further embedded the archipelago in global popular imagination, though historians dispute the accuracy of some of its escape narratives.
Transportation ended formally in 1938, and the last prisoners departed in 1953. The islands were subsequently managed in part by the French Space Agency CNES, whose Kourou launch complex brought new infrastructure nearby. Île Royale and Île Saint-Joseph are now open to day visitors via the morning ferry from Kourou. The restored chapel on Île Royale features convict-painted murals, and the intact réclusion cell blocks on Île Saint-Joseph remain the most evocative preserved structures. A small museum on Île Royale documents the penal era with photographs, prisoner registers, and period artifacts. Capuchin monkeys descended from animals kept by prison staff now roam freely across both islands.
Why it matters
The Îles du Salut housed the most internationally recognized section of France's South American penal colony from 1852 to 1953, including the confinement of Alfred Dreyfus on Île du Diable—an imprisonment whose injustice ignited the Dreyfus Affair and reshaped French political and civil life at the turn of the 20th century.

Tips for visiting

Can visitors access Île du Diable, where Dreyfus was imprisoned?
Île du Diable is not open to the public; it remains the property of the French Space Centre (CNES). Visitors can view it from a short distance from the shore of Île Royale.
Is the visit suitable for children?
The islands are suitable for children comfortable with boat travel and moderate walking. The wildlife—including monkeys and sea turtles—adds significant appeal for younger visitors alongside the historical content.
