Piton Haüy

Piton Haüy is a volcanic summit in Reunion Island reaching approximately 2,407 meters in elevation. The peak comprises two connected volcanic cones that sit within the larger Piton de la Fournaise massif.

The summit formed through successive volcanic eruptions that shaped Reunion Island's geology over millions of years. This ongoing volcanic activity created the distinctive landscape that defines the region today.

The summit takes its name from a French mineralogist and forms part of a protected national park. Visitors who trek here experience the volcanic landscape as a living connection to the island's geological heritage.

The hike to the summit follows a forest road leading to Pas de Bellecombe and is accessible for those with moderate fitness. Warm clothing is essential as temperatures drop significantly at night and mist often rolls in.

Inside the larger volcanic cone sits a smaller cone reaching approximately 2,345 meters in height. This nested formation reveals how volcanic processes can create intricate structures within structures.
