IN ENGLISH · FOR VISITORS
Réunion en clair explains the official open data of Réunion Island, a French overseas department in the Indian Ocean. This page sums up what is most useful for visitors. The rest of the site is in French.
Tourist offices know the current state of hiking trails (often closed after heavy rain), opening hours and local events. Check with them before heading to the cirques or the volcano.
The island has 45 waymarked « sentiers marmailles », short and easy trails designed for children. The shortest ones:
The National Park lists 214 practised canyons, 28 of which are banned by official order (water catchments, rockfalls). Flash floods can happen even when the coast is sunny: always go with a qualified guide.
River flows can jump from a few cubic metres to several hundred cubic metres per second in a single day of heavy rain: the highest daily mean recorded in our data is 763 m³/s. Never cross a flooded ford (« radier ») and stay away from riverbeds when it rains in the uplands.
In 2025, 924 road accidents with casualties caused 42 deaths on the island. Roads to the cirques are narrow and winding; allow extra time, especially at dusk.
