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.

Beautiful but I wonder if it shouldn’t be upgraded to black? If I compare it to La rumsteak and corpia 2.0 (both black trails) it seems only fair to name it black?
In these incredible dry conditions there’s not much use in using your brakes which makes it quite sketchy

Super dry when ridden today (4 Sept) and good conditions. The last 1/3 of the trail is super steep with some tight, off camber switchbacks. A great trail for an advanced rider.
We hope you've been enjoying Trailforks!
