Get ready for a challenging mountain biking adventure on the Washington Gulch and Snodgrass Loop. This difficult route spans 18.4 miles (29.6 km) and involves a significant elevation gain of 2604 feet (794 metres), typically taking around 3 hours and 13 minutes to complete. As you ride, you'll experience diverse terrain, from winding through vibrant aspen groves and wildflower meadows on the Snodgrass section to navigating alternating dark timber and sunlit clearings along Washington Gulch. Keep an eye out for impressive vistas of Gothic Mountain and the broader Elk Mountain Range, which provide a stunning backdrop to your ride.

Before you head out, be aware that a key part of the Snodgrass Trail crosses private ranch land. This means seasonal closures are common, usually from mid-August through early September, so always check local conditions before planning your trip. The route is generally well-maintained and clearly marked, making navigation straightforward once you're on the trail. You'll find convenient access points close to the town of Crested Butte, which makes starting your ride relatively easy.

This loop offers a true taste of the diverse natural beauty found in the Crested Butte area. It combines the scenic charm of the Snodgrass Trail, known for its open meadows and views of Mt. Crested Butte, with the more rugged character of the Washington Gulch Trail. The varied landscapes, from dense forests to expansive mountain vistas, highlight why this region is a favorite for mountain bikers seeking both challenge and stunning scenery.
