From the small "city" of Cilaos take the road of "Bras-sec" for around 2 kilometers and stop at the so-called place "Le Roc", at about 1350 meters.
Follow the very good trail in the forest up to the "belvédère de la découverte", then the plateau of "grand Matarum" at 1900 meters and the pass at 2500 meters. This is a very steep part, but with a good trail which looks like stairs...
From the pass go to the hut "Caverne Dufour" in 5 minutes, then take the less steep trail up to the top at 3070 meters, through rocky slopes and above the 3 cirques of Salazie, Cilaos and Mafate.
This ascent is possible in a single day but very long, it's possible to stay at the "Caverne Dufour" hut at 2500 meters in order to reach the summit for sunrise and to avoid the cloudy weather after 10 AM.
No technical gear is required, just good hiking shoes, (a lot of) water, a jacket in order to protect from the rain, frequent on this mountain.
Also warm clothes, the weather can be windy and cold above 2000 meters. Temperatures sometimes below freezing before sunrise.
