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.
Keepers of the Patos Light are a nonprofit partner group that operates a small interpretive museum during the summer weekends from June through September, based on weather and available volunteers.
Patos Island State Park is located five miles northwest of Orcas Island in San Juan County. It is accessible only by boat and there is no commercial ferry service to the park. The nearest launch sites are at Point Roberts Marina (13 miles north), Blaine Harbor (11 miles northeast), and Squallicum Harbor in Bellingham (24 miles east).
