Trail Overview

This is an easy 10-mile route through the Challis National Forest that is a full-width graded road, accessible by any high-clearance vehicle. It goes north from the Custer Motorway, accesses Mosquito Flat Reservoir and Campground, and goes northeast for 10 miles until the intersection with Sleeping Deer Road. It's mostly smooth and graded the whole way, with small loose rocks and gravel. There's a 6-inch deep creek crossing over smooth river rocks, and a cattle guard, and shelfier sections as it traverses the hillsides. The views are really nice the whole way of the surrounding mountains. This route will most likely be taken by those exploring up to the Twin Peaks Lookout Tower or as a scenic backway from Challis to the Custer Ghost Town, or by dirt bikers accessing the single track north of this road. It's overall easy with no obstacles.

Only drove the first half of the trail from Custer Motorway to Mosquito Lake. When dry, passable for more passenger vehicles, but a little steep in places and a crossover or AWD would be a better suited. The lake and campsite are very scenic and quiet.
