About

BLM campground. Welcome to the northwestern-most point in the lower 48 states! Patos Island is a wild and remote 200-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 . Patos Island Lighthouse, built in 1893, stands on the western-most end of the island, providing light and reference to mariners.
