Visit Crested Butte in spring

When you visit Crested Butte in spring, you’ll witness a time of change in the Gunnison Valley. From March to June, the valley transforms from a snow-covered winter wonderland to an emerald-green paradise. It’s a quiet time of year in Crested Butte, where you’ll encounter few other visitors. The spring lull is less pronounced in Gunnison, which attracts mountain bikers eager to hit the trails at Hartman Rocks. Boaters of all types seek out high water on the Gunnison Valley’s creeks and rivers during spring runoff.

Mountain biking season in Gunnison

Spring brings dry trails and high-desert blooms to the rolling, sage-covered hills of Hartman Rocks Recreation Area. Hartman’s is the first spot in the Gunnison Valley to dry out in spring. The exact opening date changes every year—it depends how quickly the snow melts. It can be as early as mid-March, or as late as early June. Follow Gunnison Trails on Instagram for updates.

When Hartman Rocks does open, locals and visitors alike flock there to take advantage of prime mountain biking conditions. Spring snowmelt keeps the trails tacky, and spring weather in sunny Gunnison is often ideal for riding.

Mud season in Colorado

Spring in the mountains is sometimes referred to as “mud season.” Snow melts, turning trails and walkways to muck. Never travel on a muddy trail. If you encounter an isolated patch of mud or a puddle, ride or hike through it rather than around it. This reduces the impact on the land surrounding the trail.

Plan your route in advance to avoid mud. The best way to do this is to check Crested Butte Mountain Bike Association’s trail conditions report, which is updated frequently in spring. Stick to trails listed as dry.

Seasonal trail closures

Mountain bikers who make the pilgrimage to Gunnison in spring need to be aware of annual trail closures during this season. The Signal Peak trail system and the south side of Hartman’s are affected by spring wildlife closures. Here’s everything you need to know about spring trail restrictions.
