Posey Island Recreation Site
Welcome to the northwestern-most point in the lower 48 states! Posey Island is a wild and remote one-acre island in the beautiful Salish Sea. The mountains of Canada and the spectacular Cascade and Olympic mountain ranges provide scenic backdrops to this special area. Recreational activities include hiking, camping, boating, sea kayaking, watching wildlife, and viewing wildflowers along the beaches, wooded areas, and at overlooks. The BLM cooperatively manages the area with Washington State Parks.
