Trail Overview
FS 9400510 is a 1.7-mile out-and-back route through Colville National Forest. This single-lane dirt road begins with deep, frequent ruts and low tree cover over the roadway. The ruts repeatedly cross the road and require careful tire placement. The main challenge is a rocky hillclimb with two possible lines: the left is steeper but relatively even, while the right follows a rough, rocky face with significant off-camber terrain. Conditions smooth out considerably at the top before the route ends at an intersection. FS 9400510 is open seasonally to highway-legal vehicles.
Difficulty
FS 9400510 is rated moderate. Deep cross-ruts, the rocky hillclimb, and the choice between a steep line and a rough off-camber line make this a technical route. A high-clearance 4WD is highly recommended. Wet conditions may significantly increase the difficulty of the ruts and rocky climb.
