Réunion packs three volcanic cirques, an active volcano you can walk to the edge of, and a coral-reef lagoon calm enough for swimming laps into one island barely the size of a large county. This five-day loop starts on the lagoon coast at Saint-Gilles-les-Bains, climbs the famously switchbacked road into Cirque de Cilaos for a soak in its thermal baths, catches sunrise light over Cirque de Mafate from the Maïdo viewpoint, and spends a full day on the slopes of Piton de la Fournaise before a last morning at a Creole market and in the water on a beginner canyon. Real hotels, real guides, and 2026 prices for every stop.
Day 1Arrival & the Lagoon of Saint-Gilles
A short run from the airport to the island’s lagoon coast, with the afternoon spent in the calm, reef-protected water at L’Hermitage-les-Bains.
🚗 Self-Drive — Roland Garros Airport to Saint-Gilles-les-Bains
~30 min · ~14 miles via the RN1

🤿 Guided Snorkel — L’Hermitage Lagoon
~2 hrs, guided · ~$45 USD / person
Réunion’s largest coral-reef lagoon, calm and shallow enough to snorkel without a boat, with parrotfish, sea cucumbers, and the occasional green turtle over the reef flat just offshore from L’Hermitage-les-Bains.
