Trail Info
The BLM has completed the reconstruction of the Croy Trails and they are open to the public. Heavy accumulations of tumble mustard weed are making passage along some sections of the trails difficult.

Description / Access Information
Hidden Valley TrailThis motorized, shared-use singletrack is west of Bullion Gulch. It makes a good ride in either direction. Many prefer to travel it counter-clockwise to descend through the turns found in the southwest portion of the loop. Others prefer counter-clockwise; to avoid the loop portion of the trail with a stiff climb.

The route includes many swooping turns and a rolling character that keeps you on your toes. The landscape is one of mostly open sage covered hills tilted to the south. This open and sunny orientation helps make this an early season favorite.

At one point the trail passes briefly through an Aspen grove. Here, the trail makes a series of dollar-sign $ turns before breaking back out into the region's more typical, open character. The 13 bermed turns found near the southwest side of the loop are a pleasure to climb, or descend on.  

Access to the Hidden Valley Trail is off of Bullion Gulch Road - 1.5 miles up the road from its intersection with Croy Canyon Road. There is very limited parking at the start of the trail in Bullion Gulch. Many people approach the trail by parking at the Croy Trailhead, which is 3.8 miles west of Hailey off of Croy Canyon Road. Look for the small street sign marking Trailhead Road on the right/north as you are headed out the canyon. Park at the Trailhead, then take the Bullion Connector Trail to Bullion Gulch and the start of the Hidden Valley Trail.
