AF Canyon Overlook Trail
The Overlook Trail is a nice out-and-back ride to a viewpoint high above the confluence of the South Fork and North Fork of American Fork Canyon. From here, you can look straight down at Mutual Dell, south at Mount Timpanogos, west down American Fork Canyon all the way to Utah Lake, and northwest at the granite peaks bordering Lone Peak and Little Cottonwood.From the Timpooneke trailhead, this is an intermediate-technical ride most of the way, with upper-intermediate the last mile or so. It's 9.6 miles round trip, with 1200 feet of elevation change.
The actual Overlook Trail branches off the Mud Springs trail at its highest point, about 1/2 mile from where it branches off Ridge 157. I like the ride from the Timpooneke trailhead, which I describe here, but you can get there by starting at Pine Hollow, Salamander Flat, the Alpine Loop Summit, South Fork, or if you're crazy enough, you can even climb up Mud Springs from the bottom end. At the trail's end, there's a flat area with an abrupt cliff on your left. You can look almost straight down on camp Mutual Dell. Walk or ride up the tiny steep hill to the west, and you're looking straight down American Fork canyon, across the lake, and into the west desert.

Getting there: From I-15, take the Alpine-Highland exit and drive 7 miles to the mouth of American Fork Canyon. Pay your $6 (as of 2009) fee there. Five miles later at the fork in the road, go along the south fork of the river. About 4 miles up, there's a T in the road. Turn right into the Timpooneke Campground road. The parking area is on your left about 1/4 mile later. Start your ride by heading past the bathroom,  then straight into the small canyon along the creek. You can also Get to the Mud Springs and Overlook Trail via Pine Hollow, Salamander Flat, the Summit parking area (Ridge 157), or even by coming up from South Fork and heading south on 157 to the Mud Springs junction.
