A key climb for the 2025 and 2026 French National Junior Championships, organized in the Vals du Dauphiné region, which still bears the inscriptions on the ground as I write these lines! A really tough climb, it stings!

Lake Paladru is very popular in the summer, especially on weekends. Swimming is possible; there's a small, well-equipped beach.

Located at the northern end of Lake Paladru, this wetland is fed by the Courbon stream. It is a true extension of the lake, rich in biodiversity and very pleasant.
