Cascade du Trou noir, Natural waterfall in Saint-Joseph, Réunion Island, France.
Cascade du Trou noir is a waterfall that drops roughly 11 meters into a natural pool, forming part of the Langevin River system in the southeast region. The water collects in a clear basin surrounded by rock faces that feed the river below.
The waterfall was recognized as a natural site during the early development of Réunion Island's hiking trail network. It became integrated into the region's infrastructure for accessing natural attractions.
Local people come here to gather and spend time together surrounded by nature, making it a place where the community connects with the landscape. The basin and surroundings have become woven into the rhythm of daily life in the region.
The easiest way to reach this spot is to park near the Bailay bridge and follow a gentle path along the right riverbank. The walk is short and fairly straightforward, making it accessible for most visitors.
The basin at the waterfall's base contains trout that visitors can spot using diving masks in the clear mountain water. The fish have grown accustomed to people and often appear while swimmers are in the water.
