What you need
Parking and passes
Most Colville National Forest trailheads are free. A few developed sites need a Northwest Forest Pass, so check the trailhead sign.
Getting there
The hike starts at Iron Gate Trailhead. Save directions offline before you leave, since mountain roads often lose cell service.
