There are numerous ways to get to Frontside from the main parking TH. This route starts on Prime Cut which is directly across the TH parking entrance and gradually climbs for 2 miles on excellent singletrack. Stay to the left @ the Chutes & Ladders jct. and through the upper parking area to the first singletrack on your right. This is the initial climb to get to Joe's Ridge and Zippety Do Da. Awesome singletrack through pinyon and juniper trees along the "Frontside" of the Book Cliffs. Stay RIGHT at both Joe's and Zippety. The switchbacks coming up are probably the most technical section of the lower portion of this trail and then into an open area heading west. Western Zippety Trail is on your left, stay right and on up to Coal Gulch Rd. which is well maintained. Take this road approx. 2.1 miles to a "hidden jct." on your right at a bend in the road. Now the real climb begins 2.2 miles on mostly singletrack to an amazing viewpoint. Mileage to here is 11 miles. From here you retrack to Western Zippety for an easier, faster way back to the TH or back up the switchbacks to finish out on either Zippety Do Da, Joe's Ridge, Kessel Run or Prime Cut. For the super human, try Chutes & Ladders to end. Great trail with many options.
