Be prepared for a day in the backcountry: deep creek crossings, rough terrain, prolonged exposure above timberline, and afternoon thunderstorms are part of the experience. But the picturesque Brush Creek drainage and the views from the pass make the pedaling (and pushing) worth all the effort. Take plenty of food and water and rain gear. Before you head out, check in with local bike shops in Crested Butte for an update on conditions and directions.
