Aspen to Crested Butte Mountain Trek

  • This scenic mountain trek from Aspen to Crested Butte begins at the entrance to the Maroon Bells Wilderness - some of the most beautiful and extensively photographed peaks in North America.

    You'll travel up the West Maroon Valley past Maroon Lake & Crater Lake. As the trail meanders through a variety of terrain from Aspen & Pine tree forests to wildflower fields,  you'll enjoy stunning views of North and South Maroon Bells as well as Pyramid Peak! Approximately 4-5 hours into the hike, you'll ascend a fairly strenuous and exposed stretch of trail to cross West Maroon Pass (12,490 ft.) into the Schofield basin, renowned for its fields of beautiful wildflowers. You'll meander through the wildflowers to the trailhead where a shuttle will await you and take you to Crested Butte. Once in Crested Butte you can choose to spend the night or choose ground transportation over Kebler pass back to Aspen (approx 4 hrs).

    With an emphasis on safety and enjoyment, our professional certified or trained guides will take you out on a fun and unforgettable mountain trek!
