Trail Overview

The Lolo Motorway(Forest Road 500) is a roughly 95-mile narrow, winding primitive road. The single-lane road, partially built by the Civilian Conservation Corps in the 1930, travels close to the Nez Perce Trail. Portions of this road are single-lane, and there are washouts. High clearance 4x4 only, and be prepared for a long day if you are not camping on the trail. This took us over 8 hours to complete. Be prepared for down trees and changing trail conditions. The road is free from ice and snow in mid-July and usually accessible into October. Lewis & Clark followed the Nez Perce Trail across the Bitterroot Mountains in 1805 and returned in 1806. Several stops along the trail contain information on Lewis & Clark's journey. The Nez Perce used the trail to access hunting, fishing, and food-gathering areas. This route includes a 1/2 mile side trip to Rocky Ridge Lake. Please remember a large portion of this trail follows the historical Nez Peace Trail - please pack it in, pack it out, and respect the area.

Difficulty

There are sections that I would definitely call a trail with washouts, rocks and a section on a single-lane shelf road.

We were able to drive in about 5 MI from Lochsa Lodge, before encountering impassable snow in a narrow section of trail along a side hill section.

Lolo Motorway east end closed from FR 568 junction (actual beginning) to the FR 566 junction (see picture of closure sign). Use FR 108 off of HWY12 then left on FR 566 to FR 500 which is open westerly from that point. FR 108 is approximately (did not measure) 8 miles west of Powell Campground.

Jeep Rubicon E to W. 35 miles or so E of Pierce there is a large 3’ diameter tree over the entire road. Anything above 7’ is probably not going to work. Otherwise the trail is as advertised. Didn’t touch the saw once. Little haze. Very dry even after the rain. Meadows in full bloom. 7 motorcycles one other jeep seen midweek. NFS are about working.
