Trou de Fer

Trou de Fer is a deep canyon in Réunion carved through volcanic rock, featuring multiple waterfalls that plunge into a narrow gorge with vertical stone walls. Water rushes down the cliffs and pools at the bottom, surrounded by lush vegetation clinging to the rocky slopes.

The canyon was first explored in 1989 by a French team that spent three days mapping its full length. This expedition opened the site to modern adventure sports and contributed to its growth as a destination for experienced explorers.

Adventurers from multiple countries gather at Trou de Fer to practice canyoning, making it an international destination for extreme sports enthusiasts.

This site is not visited on foot like other places – it requires specialized equipment, ropes, and safety precautions. Visitors should go with an experienced guide and be physically fit, as the descent takes many hours and demands technical climbing skills.

The canyon walls are made of porous volcanic rock that constantly weeps water, creating small springs throughout. These seeps flow down the rock faces and form a continuous network of waterfalls and cascades.
