Piton Rouge, Le Tampon, Volcanic summit in Le Tampon, Reunion Island, France

Piton Rouge is a mountain summit on Réunion, a French overseas department in the southwestern Indian Ocean. It rises to 1,926 metres at the northeastern end of the Plaine des Cafres plateau, within the commune of Le Tampon. Its broad, rounded cone is covered in low, dark green vegetation, with lighter bare patches on the lower slopes and patchwork fields below.

Piton Rouge lies at the northeastern end of the Plaine des Cafres plateau, on the territory of the commune of Le Tampon. The source documents give no account of its formation or of any eruption; they record only its altitude of 1,926 m and the passage of the GR R2 long-distance hiking trail over its summit.

The summit lies on the GR R2, a long-distance hiking trail that crosses Réunion. Walkers on this route pass the top of Piton Rouge, at the northeastern end of the Plaine des Cafres plateau, where the path is used as a stage between the high plains and the Piton de la Fournaise massif.

Hikers can begin from the Piton Textor forest parking area and follow the marked trail upward. The walk requires moderate fitness and is best started early in the morning to have adequate daylight for the return.

The GR R2 long-distance hiking trail crosses the summit itself, so walkers pass over the top rather than merely approaching it. The summit marks the northeastern end of the Plaine des Cafres plateau, within the commune of Le Tampon.
