Cascade de Bras Rouge, Mountain waterfall in Cilaos, Réunion.

Cascade de Bras Rouge is formed by the Bras Rouge, the uppermost section of the Rivière Saint-Étienne, in the Cilaos cirque. The water falls as a thin white column through a narrow cleft of smooth, rounded grey and black rock, with a yellowish brown face to the left above the notch and loose brown and yellow boulders at the base. Below, it flows on through La Chapelle.

The waterfall is formed by the Bras Rouge, the uppermost section of the Rivière Saint-Étienne, on the territory of Cilaos in the cirque of the same name. Its water continues downstream through La Chapelle. The site can only be reached from the GR R2 long-distance trail, which crosses the river a few metres upstream of the fall.

The waterfall is reached only from the GR R2 long-distance trail, which crosses the Bras Rouge a few metres upstream of the fall. Hikers on this route pass the site before the water continues through La Chapelle.

The only access is via the GR R2 long-distance trail, which crosses the Bras Rouge a few metres upstream of the fall. Plan for a mountain path in the Cilaos cirque and check conditions before setting out, as the route depends on the state of the trail and the river crossing.

The polished lava surfaces along the trail become extremely slippery when wet, creating a hazard that many visitors underestimate. Careful footing is essential throughout the hike due to these smooth rock formations.
