Big loop with a bail-out trail if you get tired of all the climbing. Climbs are steep and rutted until you get to the singletrack. The views are amazing.
Take highway 135 for 2 miles south out of town and turn onto Brush Creek Road on the left. Park in one of the parking spots (psuedo-trailheads) and ride your bike down the dirt road until you get to a jeep road on the right. You have to follow that up several climbs and go pretty far until you actually get to Strand Hill Trail. It's pretty hard to find if you're not a local.
