Canyoning Trou de Fer (Salazie Gorge)

The Trou de Fer descent is a guided canyoning day in the Salazie cirque, in the north-east of Réunion, a French overseas department in the Indian Ocean. The route follows the Bras de Caverne river through a deep volcanic gorge, with rappels, jumps and swims beneath waterfalls that fall from the rim of the cirque. Departures leave from Salazie village (97433), and the full experience, including transfer, equipment fitting and safety briefing, occupies roughly eight hours. The canyoning route covers around seven kilometres of river and rock. This is among the more demanding canyoning outings on the island and is generally considered suitable for participants with good general fitness who are comfortable in moving water and at height; it is not a beginner outing. Operators typically set a minimum age, often around twelve to fourteen, and require participants to be able to swim. Wetsuit, harness, helmet and descender are provided by the operator, while visitors bring a swimsuit, water shoes or sturdy trainers that can get wet, a towel, a change of clothes and a packed lunch or snack. Canyon Attitude, the operator listed for this route, runs guided groups with qualified canyoning instructors holding French state qualifications, which is the standard expected for commercial canyoning in France. Each outing opens with a safety briefing covering rappel technique, communication signals, jumping rules and what to do if a group member is injured. Rescue in a gorge of this depth relies on guide-led self-rescue and a call to the emergency services, so groups are kept small and guides carry first-aid and communication equipment. The best season runs from roughly May to October, with June to September offering the most stable water levels. The wet season, from about December to March, brings heavy rain and a real flash-flood risk in the cirques, and operators cancel or reroute descents whenever river levels rise or a cyclone alert is active. Visitors should expect to be cold in the shaded gorge despite the tropical latitude, and to be tired by the end of the day.
