Both tours are run by Pep's Nature, last exactly 3h and are open to all fitness levels, so the choice comes down to the canyon itself. The Chaley river option costs 50 € and suits first-timers looking for a classic introduction to canyoning between Lyon and Chambéry, with natural slides, jumps and rappels on a well-known waterway. The Tréfonds Pernaz route costs 55 €, and the name suggests a more technical or committed descent, likely with narrower gorges and a higher exposure factor. That 5 € gap reflects the additional challenge of the terrain. If it's your first time in a wetsuit, start with the Chaley. If you want more intensity from the first session, go Tréfonds Pernaz.

Wear a swimsuit under your clothes and bring a change of dry clothes for after. Pep's Nature provides wetsuits and helmets for both 3h sessions, but close-toed shoes you can get wet (old trainers work) are strongly recommended.
Getting there
The meeting point is confirmed with your instructor after booking, as both tours operate between Lyon and Chambéry, so coordinate directly with Pep's Nature once your reservation is confirmed.
