Patos Island Marine State Park

Turning into Active Cove between Patos and Little Patos islands, you'll feel like you're landing on the moon. A pebble beach leads to a bare, gray, rocky outcropping. Once you have beached your craft or dinghy, walk to the top of the butte and savor the out-of-this-world views.

The landscape shifts as you wander up, into a colorful forest of Pacific madrone trees and follow the half-mile path to a lonely lighthouse run by the U.S. Coast Guard. The dramatic rock formations at the point are punctuated by yellow lichens and kelly-green moss.

Up for a scavenger hunt? Find the Coast Guard international boundary marker in front of the lighthouse and take the paved path back to a former Coast Guard station, now a ruin, and spy the former helicopter landing pad. Patos is only a couple miles from Canadian waters, and is the northernmost of the San Juan Islands.

If you're planning on a longer stay, grab one of the park's first-come, first-served campsites, pitch your tent and take in the beauty of this rare, haunting isle.
