The Creek Side Loop shares a parking lot with the Mount Si Trail, which can be very busy on the weekends. Head towards the picnic area with an area map displaying the Mount Si Natural Resource area map and history. Continue past a water spigot and spot the Creek Side Loop dedication placard on the left. Turn left here, following a graveled trail lined with large ferns. Huge branches reach over the trail, wearing thick blankets of moss.

You’re about halfway when you cross the bridge over a creek. The trail soon meets the Mount Si trail. Turn right to return to the trailhead, going left will lead you up the difficult trail to the Mount Si summit. Another bridge crossing offers stairs down to the creek, an optional respite from the busy trail. Cross the bridge to return to the parking lot.


The Creek Side Loop is dedicated to Frances North, a long-time North Bend resident and Washington State Representative who sponsored the bill which saved Mount Si from clear cutting by establishing the Mount Si Natural Resources Conservation Area in the 1980’s.
