Piton Dugain, Mountain peak in Les Cafres Plain, Réunion.

Piton Dugain is a mountain summit in the Les Cafres Plain that rises to about 1,755 meters (5,757 feet). It sits east of Bourg-Murat and forms part of the Piton de la Fournaise range.

The peak takes its name from Jean Dugain, an 18th-century hunter who explored the highland regions in search of runaway slaves. His explorations left a lasting mark on the local geography and history.

The summit holds an oratory, a small place of prayer rather than a chapel or tomb. The peak's name comes from Jean Dugain, an 18th-century hunter of runaway slaves who scouted the island's highlands for the authorities.

The summit lies at 1,755 m in the Plaine des Cafres, east of Bourg-Murat in the commune of Le Tampon, reached from the Bourg-Murat side. The oratory stands on top, so the last stretch is a short walk rather than a climb. The mountain sits about 40 km from Saint-Denis and 11.5 km from Le Tampon; the surrounding land is forested and the nearest higher point, Nez de Bœuf at 2,089 m, is 3.3 km away.

Jean Dugain's son participated in a historic climb of Piton de la Fournaise in 1801 alongside explorer Jean-Baptiste Bory de Saint-Vincent. This family connection links the peak to one of Reunion's most important scientific expeditions.
