Piton Bonnet de Prêtre, Mountain peak in Cirque de Cilaos, Réunion Island
Piton Bonnet de Prêtre is a 1,710-meter (5,610-foot) summit featuring near-vertical ridges in the Cirque de Cilaos on Réunion Island. Endemic plants cover the steep rock faces that define this dramatic peak within the valley.
This rock formation developed from ancient eruptions of Piton des Neiges and was shaped by geological collapses. These processes created the current bowl-like structure of the Cirque de Cilaos with its steep walls.
The mountain takes its name from its shape that resembles a traditional Catholic priest's hat. This distinctive outline makes it easy to spot from many vantage points across the region.
The peak is best viewed from the road toward Bras Sec, where trails pass through surrounding cryptomeria forests. The area is accessible but requires sturdy footwear and care on the rocky paths.
The near-vertical walls demand specialized climbing techniques, with branches and roots serving as handholds in the steepest sections. This quality makes the route appealing to climbers seeking a genuine challenge.
