Skyline Drive - 75 miles, Highway 31 to Interstate 70
The Skyline Drive is a high-altitude dirt road that runs from the top of Spanish Fork Canyon on the north to Interstate 70 in Salina Canyon on the south. The ride described here starts on Highway 31 above Fairview Canyon and is 75 miles long with around 5500 vertical feet of total climbing, 8000 feet of descending. Starting altitude is 9400 feet, top altitude 10,700. For about 60 miles, you'll go up and down  at an average altitude of 10,000 feet before the final long descent to 6500 feet in Salina Canyon. The trail can be ridden as a multi-day with primitive camping, or as an epic one-day. You need a 4-wheel drive support vehicle.
