Piton Chisny

Piton Chisny is a summit within the Piton de la Fournaise volcanic massif, rising to roughly 2,400 meters above sea level. It stands prominently above the surrounding plateau and commands panoramic views across the volcanic landscape.

The summit was formed by a strombolian eruption during the 9th and 10th centuries that shaped the surrounding landscape. This volcanic episode left deep deposits that altered the region's terrain.

The peak is named after a cartographer who surveyed Reunion Island's coastlines during early exploration. This naming reflects the island's connection to its geographical discovery and mapping heritage.

The ascent starts from the Volcano Road and gradually reveals expanding views across the landscape as you climb. Sturdy footwear and preparation for changing weather conditions are important at this elevation.

At the eastern base of the peak lie the Aubert de la Rüe craters, also called Red Throat craters, which served as the final ejection vents. This crater landscape clearly shows the volcanic activity that shaped the area.
