Part of the High Country trails system.
Pass Trail is a great mountain bike ride or hike for most everyone. Climb up the Pass Creek Trail a couple miles to the base of Engineer Mountain. Turn left where the Pass Creek Trail meets the Engineer Mountain Trail just above timberline and head back down the face of Engineer through spruce, aspen, and meadow. Rejoin Hwy 550 just below the truck ramp and pedal 4 quick miles back up to your car. For a hiking variation, hike up to the base of Engineer mountain, and go for the summit, or just turn around and go back the way you came at Picnic rock (you’ll know it when you see it). Bring a lunch and have a picnic.
