Trail Directions
From the Marina, start out on the East Shore Trail for 1.7 mi until the end of the pavement. Keep going straight on the dirt trail a short distance, then turn left onto a skinny wooden bridge. Past the bridge, turn left at the fork onto Honker Bay Trail. Honker Bay follows the lake shore for about 1.5 miles, eventually ascending from the shoreline. At the top of the hill climb, turn left onto Columbine. This single-track trail winds its way down for 2.2 miles to a creek bed, where you turn left again to head towards Bass Cove. Go straight on Bass Cove for 1.8 miles towards the dam. After crossing the dam, the trail becomes West Shore, which leads for 1.8 miles back to the Marina.
