For the rider who's looking for an epic ride in American Fork Canyon, here it is. The Tour de Forks hits North Fork, Mineral Fork, Dry Fork, South Fork Deer Creek, South Fork American Fork, and Tibble Fork in a monster 30-mile ride. Absolute altitude change is 3100 feet, climbing is about 4600.
I took 6 hours to do the loop. My excuse is, I was waiting for my dog on the downhills. But allow yourself plenty of time. It's a monster ride.
If you've seriously underestimated your leg power, you can bail out by skipping the southern loop and dropping directly down Tibble Fork. Bailouts are also possible at Forest Lake, Old Trench Road 181, and Mill Canyon. If you're not VERY familiar with these trails, take a full topo map and GPS unit with you.
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. Park, then ride straight past the outhouse onto the gravel road that heads up along the river.
