Start at the Trapper Creek Trailhead and follow the trail 0.2 mile to the first junction. Turn right at the fork for a 1.5-mile stretch along the Whitefish Trail and a gravel road. The route joins the Pacific Crest Trail at Pengra Pass and follows it past lakes, campsites, and views of open meadows (where you may spot roaming black bears) to the foot of Diamond Peak. At mile 12.6, turn right onto a climber’s trail for the 1.3-mile stretch to the top of Diamond Peak. Look out onto lake-speckled landscapes from this Cascade summit, then descend back to Waypoint 18 and turn left, following the same route back to the trailhead.
