Wind through pleasant forest to arrive at two buggy mid-elevation mountain lakes. Start at the Pioneer Horse Camp near the end of Forest Service Road 12 and climb 1,000 feet in 3.5 miles to reach the junction with Bell Pass Trail 603.3. Turn left at the junction, enter the Mt. Baker Wilderness in about .25 miles and reach Lake Doreen in .75 miles. Soon after find a spur trail to the right leading to campsites on the east side of Elbow Lake. Continue on the main trail; descend gently past Elbow Lake, through some boggy areas and among ancient trees for 1.5 miles to a view of the Twin Sisters Mountain Range. Hike another two miles to the northern trail terminus near the Middle Fork Nooksack River. There is no bridge over the river to reach the north trailhead and fording the river may not be possible during high river flows.
Elbow Lake and Lake Doreen are popular fishing spots.
