Îles du Salut

Three islands off the coast of Kourou

The Îles du Salut are a small archipelago in French Guiana, about 14 kilometres off Kourou on the Atlantic coast. The name refers to three islands: Île Royale, Île Saint-Joseph and Île du Diable, or Devil’s Island. Seen from the mainland, their green slopes and palms can suggest a tropical escape. Their history is much harder: from the nineteenth century onward, the French state used the islands as part of its colonial penal system, sending prisoners into an isolated Atlantic environment. Today visitors encounter both a protected natural setting and the physical remains of that history.

The French Ministry of Culture’s heritage register treats the islands as one connected historic landscape. Its 2012 protection covers buildings and improvements associated with the colonial penal colonies, Amerindian remains and the ground itself, subject to listed exceptions. The record identifies the public space agency CNES as owner, while certain parcels on Île Royale are assigned to the Conservatoire du littoral and the environment ministry. This administrative arrangement reflects the site’s unusual present-day setting: heritage conservation, coastal protection, ecological management and the nearby spaceport all meet here.

That geography affects a visit. The islands lie below the trajectory used for launches from the Guiana Space Centre, and the CNES management documents describe operational restrictions, including evacuation when a launch requires it. The archipelago is not a resort with unrestricted movement between beaches. Access depends on boat schedules, safety instructions and conservation rules. The most practical way to understand the place is to begin on Île Royale, where the regular passenger service lands, and to treat the other islands as part of the wider story rather than assuming they are open for a walk ashore.

A penal-colony landscape, not a prison museum alone

From the mid-nineteenth century, the French penal administration established a settlement in French Guiana that became infamous for forced displacement, harsh conditions and isolation. The Îles du Salut formed only one part of a much larger system spread across the mainland and the coast. Prison buildings, administrative structures and traces of the settlement remain on the islands, but the landscape should not be mistaken for a complete or neutral account of imprisonment. Many structures have disappeared, and surviving ruins tell only part of the experience of the people sent there.

Île du Diable is particularly associated with Alfred Dreyfus, the French army officer convicted of treason in a notorious miscarriage of justice and deported there in 1895. The Ministry of Culture’s account of his exile helps explain why the island became internationally known. But Dreyfus was one prisoner in a system that confined thousands of men under very different circumstances. A visit that focuses only on his story risks turning the archipelago into a dramatic backdrop and overlooking the wider history of colonial punishment, forced labour, separation from families and lives lost in Guiana.

Île Saint-Joseph also belongs to this history, while Île Royale developed as the principal administrative and residential centre of the island settlement. The official heritage register includes remnants associated with Amerindian presence as well as the penal period, a reminder that human history here did not begin with the prison administration. The islands’ layered past is therefore broader than a single famous prisoner or a collection of atmospheric ruins. Reading the landscape requires attention to who built, occupied and governed it, and to the natural environment that shaped survival and movement.

What visitors can see—and what they cannot

For ordinary day visitors, Île Royale is the practical focus. Promaritime Guyane’s regular passenger catamaran lands there; the operator says its service does not land on Île Saint-Joseph, and landing on Devil’s Island is prohibited. The latter restriction matters: views of Devil’s Island from the boat or from Île Royale are not permission to go ashore. Access limits can also reflect safety, conservation and the sensitivity of the historic site. Do not arrange an unofficial landing or assume that a private boat changes the rules.

On Île Royale, visitors can walk among the former settlement’s remains and see how its buildings occupy a compact island landscape. The former commandant’s house now serves as an inn, and other surviving structures include religious and penal buildings; some have been restored, while others remain ruins. Their condition varies, and facilities or rooms may be closed for conservation or operations. Allow time to look beyond the most photographed views: the relationship between the buildings, the shoreline and the vegetation helps explain how isolated the settlement was.

The islands are also a protected natural site. The boat operator’s rules prohibit hunting, collecting plants, cutting vegetation, feeding or touching wildlife, and lighting fires; passengers must take their rubbish back. Smoking is prohibited on the boat. These are not decorative requests: the small, exposed environment is vulnerable to disturbance, and the islands’ heritage and wildlife share limited space. Stay on paths where directed, follow staff and gendarmerie instructions, and do not enter unstable ruins. Weather, sea conditions and launch operations can alter what is accessible on a given day.

Boat times, tickets and planning a day trip

At the time checked on October 8, 2026, Promaritime Guyane listed one regular crossing daily from Kourou, departing at 8:30 a.m. and reaching Île Royale around 9:30. The return boat leaves the island at 4:30 p.m. and the crossing takes about an hour. The operator asks passengers to arrive 45 minutes before departure and 15 minutes before the return sailing. These are the published regular-service times, not a guarantee for every future date: confirm the booking calendar and any operational notices before travelling.

The operator’s online booking system lists fare categories for adults, children under 12 and babies under one; the prices and available sailings are presented through a date-specific reservation form. Because fares can change and availability depends on the selected day, check the live ticket page instead of relying on an old quoted amount. Reserve ahead, especially during school holidays or busy travel periods, and keep the confirmation accessible. The standard passenger crossing is a day trip, so a missed return boat can create a serious logistical problem.

Plan for a long day exposed to sun, wind and changing sea conditions. Carry water, sun protection, suitable walking shoes and any food you need, while taking all waste back to the mainland. Before departure, check the operator’s instructions and confirm that the islands are open to visitors; a space launch or safety decision may interrupt access. The Îles du Salut are compelling not because prison ruins make an easy adventure, but because the setting brings together colonial history, a living memorial landscape and a fragile Atlantic environment. A thoughtful visit leaves time to look, learn and respect the limits that protect it.
