A legendary mountain pass that separates the High Pyrenees Natural Park from the Aigüestortes and Lake of Saint-Maurice National Park. It can be climbed from both valleys.

Good area for riding and training. Be careful if you go too far, the track ends.

The arrival from Llavorsí is amazing, long but beautiful; the descent to Espiu is almost 30 turns and is even more beautiful than being at the top. I don't want to think about what it must be like to go up there, in some areas the road surface is somewhat broken.
