Watch for a singletrack trail to your right off the main trail (the main trail will simply loop around back to your starting point along the lake).
Turn right on the singletrack and head down and then up. At the next intersection stay right (left will take you back to the Lake Padden Loop

At the next intersection, stay left and start a downhill section. Take a right a the next intersection, cross the powerline and continue heading down. After crossing a small bridge the trail will merge onto the Lake Padden Loop
