The Bras Rouge waterfall drops several tens of metres into the Bras Rouge gorge, below the village of Cilaos. You walk down to it from the centre along the Sentier des Porteurs, the old path of the spa-goers heading for the hot springs, facing the Grand Bénare and the Col du Taïbit. Allow 2.7 km out, mostly downhill, and the same way back, uphill. The National Park rates the walk easy and gives three hours there and back.

The route

The start is the car park of the salle multimédia, rue des Thermes, to the left of the church roundabout in Cilaos. Without a car, Alternéo bus line 60 runs from the Saint-Louis bus station up to the "Cilaos Ville" stop.

Follow the white and red waymarks of the GR R2, which go down a flight of steps to the Sentier des Porteurs. Soon after the start you pass the "Ti Bon Dié" wayside shrine, dedicated to the Virgin Mary and Saint Expeditus. The hot springs were found in 1815 by Paulin Técher, a goat hunter. In 1836 the engineer Ferrière began a path to take spa-goers to the baths, and the ravine nearby now bears his name. Until the road opened in 1932, visitors were carried up from Saint-Louis in sedan chairs. The porters then carried them between the village and the old baths until 1965, and one of these chairs is on display at the Maison du tourisme.

The path opens onto the Grand Bénare, at 2,898 m, the Piton de Sucre, the points of the Col du Taïbit and the Nez de Bœuf. In the distance, the Ravine Ferrière waterfall drops about a hundred metres. You cross a footbridge, then follow the road to the left of the old baths. Destroyed several times, notably by the 1948 cyclone, they ran until 1987, when the current spa, Irénée Accot, opened in the village. A sign reads "Cascade du Bras Rouge 45 mn".

The path then crosses several ravines, passes under an arch of boulders fallen from the Piton des Neiges and follows the gorge to the Bras Rouge waterfall. A rock slab on the left gives a view of it. The river owes its name to the rust-coloured deposits of its iron-rich hot springs. The warm pools upstream now lie buried under rockfall. Along the way, the Park points out the bois rouge, a poisonous tree, an orchid, *Cynorkis purpurascens*, and the Réunion Sylvan, an endemic butterfly that is critically endangered. You come back the same way, climbing a little over 300 m to the village.

Good to know

The walk is easy, but it crosses several ravines, and the river rises very fast in the rain: don't set off in the rain, and turn back if it comes. At the waterfall, the rock slabs polished by floods are extremely slippery: stay on the path and keep children close. Swimming is not supervised, and the regional health agency (ARS) warns that fresh water carries a risk of leptospirosis, above all in the rainy season. No drinking water is listed on the way: carry your own. RandoMafate shows ONF closures and the weather for the day before you set off, keeps the map offline at the bottom of the gorge, and the people close to you follow your outing on a simple web page.

Frequently asked questions

How long does it take to reach the Bras Rouge waterfall?

The National Park gives three hours there and back. RandoMafate estimates 1 h 05 of walking for the way out, downhill, breaks not included. The way back takes longer: it climbs back to Cilaos.

Is the hike suitable for children?

Yes, the Park rates it easy and presents it as a walk for the whole family. The tricky parts are the ravine crossings and the slippery slabs at the waterfall.

Can you swim at the Bras Rouge waterfall?

No official source recommends it. The slabs at the edge are very slippery, the river can swell all at once after a shower upstream, and fresh water carries a risk of leptospirosis.

What else is there to do from Cilaos?

The Sentier de la Chapelle reaches the same river further downstream, where it has cut a narrow canyon into the Piton de Sucre. It is longer and more technical. The Col du Taïbit leads to Marla, in Mafate.
