Trail Overview

This route begins at the 3-way intersection of Forest Service Roads 352, 378, and 419 from the Thompson Falls Trail. The route is two-lane for a short spell and turns into one lane of bony rock and gravel. The route is very rough in sections with ruts and steep drops close to the edge of the route. Sharp blind corners with steep slopes will be encountered. Dusty when dry, and no cell service is available. There are very few pull-outs along the narrow route. No other traffic was encountered along the route. The route will climb from 4900 to 5900 feet in elevation with some open scenic spots to view.

Trail has been cut of fallen trees till we reached the 5500' elevation of the trail. We had to turn around as the trail had quite a bit of snow still hanging on. Trail will need to be checked for fallen trees once you can pass thru
