The 1,771-acre Rattlesnake Mountain Scenic Area forms part of the southern mountainous ridge of the Snoqualmie Valley and faces the Mount Si NRCA.  This highly scenic area as viewed from the I-90 corridor is co-managed and owned by DNR and King County.  The site provides scenic and visual resources, and protects cliff terrain, wildlife habitat, numerous riparian systems, and pockets of old growth forest.  At present, public access to the scenic area is limited.  The scenic area is located outside the city of North Bend, approximately 30 miles east of Seattle.  (King County)
