Mud Spring - Mill Canyon Loop
The Mud Springs - Mill Canyon Loop, in the North Fork of American Fork Canyon, gives you a solid tough climb, fantastic views, and a rockin' tech downhill. But it demands good climbing skills, strong legs, great aerobic capacity, and advanced downhill skills. This 11-mile loop has over 3000 vertical feet of climbing, with a peak altitude of 8350 feet, and is for advanced riders only. Trail surface can be loose due to horse traffic. Season is mid-June through early October.

Getting there: From I-15, take the Alpine-Highland exit just south of Point-of-the-Mountain. Go east towards the mountains on UT-92 and continue up American Fork Canyon. There's a $6 fee (as of 2009). About 6 miles up the canyon, turn left at the North Fork junction and drive 2 miles to Tibble Fork Reservoir. Go past the dam and park in the long parking area north of the lake N 40° 28.98' W 111° 38.68', altitude 6050 ft. On your bike, head up past the bathroom, and continue straight onto gravel road as the paved road turns left. (Alternate: to riding through the river, bike over the dam and around the far side of the lake until you hit the Mill Canyon Trail 040 sign.)
