The trail ascends through coniferous forests, alpine meadows, and panoramic ridges, featuring the distinctive red earth formations.
The 'Terres Rouges' (Red Earths) are a unique geological feature composed of Permian pelites, colored red by iron oxidation. They give the route its name and provide a visually stunning contrast to the surrounding green landscapes, especially during autumn.
The best time to experience the full beauty of this trail is from June to October. Autumn is particularly recommended for the vibrant golden colors of the larches, which create a magnificent contrast with the red earth formations.
