Connects to Black Diamond Open Space (BDOS), Summit Ridge, and Lake Sawyer across the road.
How to Find It
There are a few options for trail entry to Henrys Ridge:
- Ride from Lake Sawyer trails
- Use the : Gracie Hansen Community Center parking area
- Park at the Hacienda Del Mar (Mexican Restaurant) on HWY-169 and ride SE 276th (Maple Ridge) into the neighborhood. There are trail entry points near the water tower half way up the hill. Look for the blue "King County Natural Area Boundary" signs.
