This 2.5 mile loop is located on the upper section of the Brice Creek Trail. It climbs steeply for 1 mile from near the east trailhead, passes behind Upper Tressle Creek Falls, then descends for 1.5 miles of fast and flowing rollercoaster and downhill combination. The trail ends right at the east Brice Creek TH.
This section of trail adds much to the Brice Creek ride--namely, some downhill. It's also much smoother than the main trail here, so your body gets a little rest from the jarring root and rocks. For maximum satisfaction, ride the whole thing from the lower TH at Brice.
Be careful to not confuse this trail with a little spur trail that goes to Lower Tressle Creek Falls. That trail is .3 miles long, located a couple hundred yards just east of the loop trail, and is closed to MTB's.
