Polallie Ridge Trail #1309

Trail begins at Salmon La Sac trailhead and ends at the junction with the Waptus Pass Trail. Accesses Alpine Lakes Wilderness Area.

The first 2.5 miles is uphill and fairly steep as the trail follows the ridgeline, passing through trees and open areas and over rocky bluffs. Past the 2.5 mile point, the trail runs along the north side of the ridge, going down into and up out of several basins; it is often steep. Diamond Lake is in the second basin at 4.2 miles and is the only constant water source along the trail (treat before drinking). The trail passes through two additional meadow basins before hitting the ridgetop again at 6.5 miles. Just beyond that, the old Pollalie Lookout site provides good views. The junction with Tired Creek Trail 1317 is just past that. From there, the trail descends through old growth forest to Waptus Pass and the junction with Waptus Pass Trail 1329.
