Can You Drink Tap Water in Réunion?

Tap water in Réunion is safe to drink. As a French overseas territory (département d'outre-mer), Réunion operates under French law and EU drinking water directives. Water is treated and distributed to the same standards as metropolitan France. Visitors from any country can drink tap water in Réunion without concern throughout their stay.

Saint-Denis, the capital in the north, and Saint-Pierre in the south both have reliable treated water supplies that meet European standards. The island's water comes primarily from its abundant rainfall and mountain streams, collected and treated before distribution. Réunion's volcanic terrain and high rainfall make it one of the most water-rich islands in the Indian Ocean.

The spectacular interior of Réunion — including the three cirques of Cilaos, Mafate, and Salazie — is a major draw for hikers tackling the island's renowned trails. Water from mountain streams and springs in the cirques should be treated before drinking despite appearing clean, as grazing animals can contaminate sources. Carry a filter for any multi-day hiking in the interior.

The Piton de la Fournaise volcano in the southeast is one of the world's most active and a major visitor attraction. The surrounding national park area has treated water at visitor facilities. In very remote volcanic terrain, carry sufficient bottled or filtered water as natural sources may be affected by volcanic minerals.

Overall Réunion is one of the safest water destinations in the Africa and Indian Ocean region. Tap water is safe throughout the island. Bottled water is widely available for those who prefer it, but drinking from the tap carries no risk in any urban or rural area.
