Descente iconique des Hautes-Rivières. Rapide et technique. Racines au départ, jardin de pierres au milieu, ardoise meuble en bas. La section d'ardoise accroche en fait mieux par temps humide.

Iconic descent of Les Hautes-Rivières. Fast and technical. Roots at the start, a rock garden through the middle, loose slate at the bottom. The slate section actually grips better when wet.
