Access: head towards Cilaos via the N5. Follow the road to the “Burrel” bus stop
(S/E) From the Burrel bus stop, take the path which starts on the left at the bend in the road. The path is narrow from the outset, with some sections already vertiginous. It quickly crosses sections of unstable scree: take care not to slip on this ground. Soon, the first clearings offer views of the Dimitile and the southern part of the Cirque de Cilaos.
(1) You’ll reach the Parc à Tortues. This is a former inhabited islet. After this relaxing stretch, the path quickly follows a series of narrow and vertiginous sections with an impressive sheer drop over the Bras de Cilaos. Some sections are fitted with cables, but you still need to take particular care.
(2) You’ll reach the ford on the Grand Bras de Cilaos. Directly opposite is the Parc à Dennemont. Cross the river just above a small waterfall and its pool. Be careful, however: here, you’ll often have to wade through the water. Then rejoin the path on the opposite bank, which runs alongside the river. The vegetation is rather dry, and the first views look north towards the Cirque de Cilaos.
(3) When you reach Trois Bras, ignore the path on the right leading to the Plateforme and head left to fords the Bras de Saint-Paul. This is where the challenging sections begin: you’ll need to climb 600 metres in altitude to reach the Îlet à Cordes.
(4) A short climb begins at the ford, followed by a long flat stretch: this is the Îlet du Bois de Nèfles, largely covered in chocas. You’ll soon be able to enjoy a view of the Cirque de Cilaos and the remaining ascent. Here too, you’ll need to watch out for scree slopes, some of which are secured with cables. You climb gradually, and before long the Bras de Saint-Paul seems far below. The views gradually open up, taking in the Îlet à Pères and the southern part of the Cirque de Cilaos. The path is very rocky, quite exposed and climbs in tight hairpin bends. Some sections are narrow and vertiginous. Reaching a wayside shrine marks the halfway point of the ascent.
(5) Shortly after the wayside shrine, ignore a faint path that branches off to the right and stay on the main path. The second part of this walk is easier going and offers memorable views of the cirque. It is, however, much more exposed.
(6) Allow at least an hour’s climb from Les Trois Bras to reach the Îlet à Cordes. The final few metres take you through the lentil fields for which the Cirque de Cilaos is famous. Enjoy a well-deserved break in these fields and return to the starting point via the same route (S/E).
