 | Old Trench-Road Trail
The Old Trench Road Trail is a relatively steep and rough singletrack that descends from Ridge 157 near Rock Springs. The recommended loop ride is 17 miles, starting at 6500 feet elevation at Tibble Fork and rising to 9400 feet. Total climbing will be about 3100 feet. The ride is recommended only for advanced riders. The climb to Pole Line Pass is long. Ridge 157 has some steep sections. The Old Trench Road Trail becomes steep and rough, requiring strength plus excellent braking and bike-handling skills. |

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.) Copyright 2002 Mad Scientist Software Inc
