Ride beside the Slate River, through aspen groves, or high above Gothic Valley on the famous 401.

A ride for the day you have
Crested Butte rewards more than one kind of ride. Start along the Slate River to get used to the altitude, find rolling singletrack in the aspens, then save the exposed alpine country for a clear day and a group comfortable with the climb. Trail conditions and private-land access can change; check before leaving town.
Easier · from town
Start at the northwest edge of town, where Butte Avenue becomes Peanut Lake Road. The Lower Loop follows the Slate River; the Upper Lower Loop climbs above it before returning toward town. CBMBA describes its full lollipop as an easy nine-mile ride; use the road or a shorter out-and-back if that is too much.

Ride from town up the recreation path to Saddle Ridge, then follow Lupine through aspens. Take the Lupine 2 descent to Slate River Road, then link to the Lower Loop or take the shorter road return. The full Lupine–Gunsight loop adds climbing and tighter switchbacks; it is not a flat beginner ride.
CBMBA route details and mapIntermediate · seasonal access
This aspen-and-meadow singletrack connects Gothic Road with Washington Gulch Road. Ride an out-and-back or use roads to complete a loop. Portions cross private property and close seasonally; a closure can prevent the complete traverse. Respect gates and check current access before setting out.
CBMBA route details and mapDifficult · high alpine
From the Washington Gulch side, 403 climbs above 11,000 feet before descending toward Gothic Road. Steep, loose sections and shared use make this a ride for confident mountain bikers, not a first alpine descent. Arrange the road connection or return before starting.
CBMBA route details and mapLupine access: Do not park or shuttle to Saddle Ridge Road. Ride or walk in from town or Mt. Crested Butte; the access agreement depends on respecting the neighborhood.
The signature ride
Trail 401, also called Trailriders, traverses above Gothic Valley with views across the mountains and, in season, tall wildflowers along the singletrack. It is a memorable intermediate-plus ride, but the altitude, exposure and climbing make it a bigger undertaking than its descent suggests.
CBMBA’s classic loop begins at Judd Falls parking, climbs Gothic Road toward Schofield Pass, then takes 401 back down. Its published loop is about 14 miles with roughly 2,283 feet of climbing; allow 2½–5 hours, and more for stops or slower riders. Starting at Snodgrass adds road miles but reduces vehicle pressure in the Gothic corridor.
Plan your return: The full classic loop follows lower 401 back to Judd Falls parking. For a shorter ride, exit at Rustlers Gulch and use Gothic Road to return to your starting point. A shuttle to the pass replaces the road climb but requires a separate plan to reunite riders and vehicles; it does not eliminate the climb on 401. Confirm shuttle service and bike capacity directly.
Gothic Road is shared with vehicles and passes through the Rocky Mountain Biological Laboratory community. Slow down through Gothic. Check road and trail conditions, carry an offline map, layers, food, water and repair supplies, and turn around for storms or soft trail.
See CBMBA’s classic 401 routeHigh trails melt out later than trails near town, and snow can return in autumn. Wildflower timing varies with snowpack and weather. When tires leave ruts, choose a dry road or wait; riding around mud widens the trail. Start alpine rides early and retreat below exposed terrain when thunderstorms threaten.
Yield to hikers and horses, and give uphill riders the right of way. Slow down, communicate, and ask horse riders how best to pass. Stay on the trail, respect closures and private property, and leave flowers for everyone. Check the land manager’s rules for e-bike access rather than assuming every trail permits them.
