Description / Access Information
Hidden Valley TrailThis motorized, shared-use singletrack is west of Bullion Gulch. It starts with an out-and-back leg. The loop portion of the route makes a good ride, run or walk in either direction. Many bicyclists prefer to travel it counter-clockwise direction, in order to descend through the turns found in the southwest portion of the loop. Others prefer to travel the loop counter-clockwise. Doing so avoids ending the loop 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.

Sections of the trail are smooth and other areas are rough and rocky.

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 southwest section of the loops features a series of 13 berms banked-turns) /turns that are a pleasure to climb, or descend on.  

Directions: Go west from Hailey on Bullion Street/Croy Canyon Road for about 4.5 miles to Bullion Gulch Road on the right/north. Head up Bullion Gulch for 1.3 miles. This brings you the Hidden Valley Trail on the left/west. The road is a little bit wider here, so there is room to park a couple of vehicles on the west side of the roadway. There is more parking available up the road; 0.3 miles up canyon on the right/east.

As mentioned above, the main access to the Hidden Valley Trail is off of Bullion Gulch Road. An alternative approach is start your trip at the Croy Trailhead. From there follow the Bullion Connector Trail to Bullion Gulch Road and the start of the Hidden Valley Trail. The Croy Trailhead is 3.5 miles west of Hailey, on the north side of Croy Canyon Road. Heading west from Hailey, look for the signs marking Trailhead Road and the BLM Croy Trailhead on the right/north.
