Bassin des Aigrettes, Natural pool in Ravine Saint-Gilles, Reunion Island, France.
The Bassin des Aigrettes is a freshwater pool in Ravine Saint-Gilles fed by a waterfall and surrounded by volcanic rock walls. It sits within a narrow gorge and connects to other pools downstream through the Saint-Gilles stream network.
This pool developed over centuries through volcanic activity and water erosion that carved out the gorge and its basins. The Saint-Gilles stream shaped the landscape, creating the natural water system visitors see today.
Local families visit this pool on weekends to swim and share meals together, a custom that reflects how the island community values water and outdoor gathering spaces. The rocky setting frames these simple gatherings, making it a natural social hub for the region.
The walk to the pool takes about 45 minutes from the outdoor theater parking area and follows a canal path. Wear proper hiking shoes because the terrain is often wet and uneven.
The water stays at a constant temperature of around 20°C year-round, making it refreshing even during the hot summer months. This steady coolness comes from the pool's depth and the continuous flow of fresh water from the waterfall.
