Piton Tortue, Mountain summit in Le Tampon, Réunion Island, France.

Piton Tortue, also called piton Vert, is an extinct crater rising to 1,809 m in the Hauts of southern Réunion, above the village of la plaine des Cafres. Its broad, sloping summit is packed with dense low vegetation, with a small cluster of taller dark trees near the middle of the slope and a thin wire fence crossing the lower part. Exposed dark rock shows near the top edge, often under cloud.

Piton Tortue is an extinct crater in the Hauts of southern Réunion, above the Plaine des Cafres. Its older name, piton Vert, comes from the dense forest covering its slopes. It lies on the GR R2 hiking route that leads to Piton des Neiges, the island's highest summit.

The name Tortue (turtle) and the older name piton Vert (green peak) both come from the mountain's appearance: a wooded summit, unlike the bare rock of nearby Piton des Neiges. Hikers on the GR R2, the long-distance trail toward Piton des Neiges, pass through pastures and then primary forest of Réunion National Park on its slopes.

Hikers can reach the summit via marked trails, with the best climbing conditions during the dry season from May to November. Sturdy footwear and weather preparation are essential, as conditions can change quickly.

Piton Tortue is also called piton Vert, after the dense forest covering its slopes. Hikers on the GR R2 toward piton des Neiges usually skirt the base of this wooded slope rather than climb it, so the old name is the one most often seen on maps and trail signs.
