Mafate, Cilaos and Salazie

There are three natural calderas, contiguous to the Piton des Neiges. A natural circus/caldera is a circular space surrounded by mountains. This space can be formed by a depression of glacial origin, it is then a glacial caldera or of volcanic origin as it can be seen and trekked in Reunion Island National Park. The three natural calderas on Reunion Island are Mafate, Salazie and Cilaos.

Reunion Island owes its fame to its natural sceneries which are mostly represented in these 3 calderas. These large mountain enclosures are visited each year by thousands of visitors who are attracted by the prodigious landscapes that can be admired there. These are all sanctuaries of mother nature and discovering them during a hike is quite some unforgettable experience.


The name Cilaos is derived from the Malagasy term “Tsilaosa”, which means, a place we can’t leave. South facing Cilaos is the driest calderas of the three. The road to Cilaos Circus is spectacular. Its 400 turns are easily forgotten so much landscape is beautiful.

Located in the center of the island, in the southern part of Piton des Neiges about 1200 meters above sea level, Cilaos has many resources. Main destination for visitors eager for nature and hiking, the circus is known for its lentils, wine, embroidery and baths. Cilaos is also famous for its canyons.

Quiet and flowery, this “nature city” is particularly embellished with the departure of hiking trails: the GR R1 (Tour of the Piton des Neiges through the 3 circuses) and GR R2 which crosses the island. Many other hiking trails allow you to discover the natural fruitfulness of Cilaos.


Mafate is the only caldera that is accessible only by foot. The only other way is by helicopter. The rugged and chaotic terrain of Mafate prevents the road from accessing it, and that add to the charm of this place.
