Lost Trail Pass

Tucked away in the Bitterroot Range of the Rocky Mountains in the northwestern United States, the road to the summit is totally paved. It’s called U.S. Highway 93. Open to traffic throughout the year, the road may be closed for short periods in winter when the weather is bad. The road cuts through the steep, rocky peaks of the Bitterroot Mountains.

The pass is 42.16km (26.2 miles) long, running north-south from Sula (in Ravalli County, Montana) to Gibbonsville (in Lemhi County, Idaho). The drive is very scenic.
