Thalasso de Saint-Gilles-les-Bains in La Réunion offers iodine-rich tropical Indian Ocean thalassotherapy on the reef-protected lagoon coast of France's most spectacular overseas island—La Réunion, a French department in the Indian Ocean whose volcano (the Piton de la Fournaise, one of the world's most active shield volcanoes) continuously creates new land while the island's calderas and cirques (particularly the spectacular Cirque de Mafate, accessible only on foot or by helicopter) form some of the most dramatic terrain on Earth. The iodine-rich Indian Ocean water used in the treatments reflects the exceptional marine biodiversity of the Réunion lagoon, whose coral reef ecosystem is one of the most biodiverse in the Indian Ocean. The Piton de la Fournaise volcanic activity, the Cirque de Mafate wilderness, and the tropical Indian Ocean thalassotherapy tradition create a Saint-Gilles experience of extraordinary natural volcanic and therapeutic tropical richness.
Insider tip — Saint-Gilles-les-Bains is Reunion Island's main beach resort, and its thalasso uses the warm, coral-filtered waters of the Indian Ocean lagoon protected by a fringing reef. The water temperature rarely drops below 24 degrees in the sea, and pools are heated year-round for a deeply relaxing experience. Basalt cliffs from Reunion's two massive shield volcanoes frame the northern horizon, and the Piton de la Fournaise — one of the world's most active volcanoes — is a 90-minute drive away for a dramatic post-session excursion. The local vanille bourbon and rougail sausage cuisine is among the most vibrant in the French overseas territories.
