Plage de Trou d'Eau lies on the Route du Littoral in Saint-Benoît, on Réunion's wet and wild east coast, about 45 km east of Saint-Denis. It differs from the sandy lagoon resorts of the west because the east coast is exposed to the open Indian Ocean and receives more rain, producing lush green surroundings and dramatic black volcanic rock shorelines. The main attraction is a natural rock pool, a sheltered basin formed in the volcanic rock where the water is calmer than in the open sea. The water is clear when conditions are quiet and the colour is a deep blue-green. The pool is small and intimate rather than a long sweep of sand, and the surrounding coast is rough, so swimming outside the pool area is not advised. There is no shark net, and visitors should stay within the sheltered pool. The mood is quiet and local: Réunionese families come at weekends, while foreign visitors are few, and the setting suits those who enjoy rugged scenery and a slower pace. Amenities are basic, limited to parking, so visitors should bring water, food and sun protection, and buy supplies in Saint-Benoît beforehand. Access is by car along the RN2, taking about 45 minutes from Saint-Denis, and Car Jaune Line 1E runs to the Saint-Benoît terminus, from which a taxi or a longer walk is needed. Because the east coast gets frequent showers, conditions change quickly, and the best months are June to October when rainfall is lower. Visitors should avoid entering the sea when swell is high and check conditions locally. The beach is rated 4.2 and rewards those seeking a less commercial coastal experience, with nearby Saint-Benoît offering shops, markets and food options for a longer stop.
