Overview
As autumn paints the eastern edge of the North Cascades in molten gold, Larch Madness welcomes you to the secluded slopes of Loup Loup Ski Bowl. Towering larches flare against crisp blue skies while a carnival of crunchy leaves swirls around racers and supporters alike. Expect an energetic mountain-town vibe where cowbells mingle with pine-scented air and wood-fire smoke from the camp-circle after-party.
The course is equal parts thrill ride and character builder: steep jeep roads, rowdy ski runs, and rugged off-trail traverses keep your heart thumping and your senses firing. Finish strong, then refuel with Rainshadow’s legendary potluck feast while swapping trail tales beneath a blanket of stars.
