Commonwealth Falls

The trailhead begins on the north side of Interstate 90 at the northbound PCT trailhead.  Travel along Commonwealth Creek only as far as Commonwealth Falls, to limit the elevation gain to 500 feet for this Easy level trip.   (For a longer trip up the basin, select the Easy+ Commonwealth Basin route.)

Park at the Summit West lot, carefully crossing the summit access road to reach the trailhead.  Don't be tempted to park at the cleared area at the top of NF-58 (the old Snoqualmie Pass Road).  Despite appearances, that is a no parking area.
