The trail starts gradually climbing up to Duck Lake, you'll pass the junction of the Hum Lake Trail, then pass Duck Lake and continue up to the pass. You'll pass one more trail junction where the Loon Creek Trail
which is on the right. Continue on the left fork, and you'll start descending to the 20-Mile drainage.
The trail drops steeply down the headwall then becomes gradual for the rest of the way. You'll pass the 20-Mile Lake Trail on your right which branches off 3 miles from the 20-Mile Trailhead.
