Pearl Pass provides a wide variety of exciting riding including rolling hillsides, difficult rock ledges, and high-mountain riding with spectacular views. Part of this trail passes alongside the Maroon Bells-Snowmass Wilderness and stays very remote, so plan accordingly. Unlicensed vehicles are allowed at the start of Trail #738 but must turn around at the pass. Trail is closed March 1 to May 27 depending on snow.
Few people know that mountain biking started in Crested Butte back in 1976, when a group of half-crazy bicyclists decided to ride their heavy, balloon-tired Schwinn bikes over Pearl Pass. Now there is an annual event in September called the Pearl Pass Tour. In one day, bikers ride from the town of Crested Butte to Aspen, a total of 38 miles. In 2009, the event was held on September 12. The date changes a bit each year, so you might want to find out the exact date before heading out.
