Located in San Juan County in Puget Sound, Patos Island has two mooring buoys in Active Cove.
The moorage area at Active Cove has strong currents flowing through it and is exposed to strong westerly winds from the Georgia Strait. Boaters should check weather reports and avoid anchoring at this site during weather forecasts which call for high pressure systems and westerly winds exceeding 12 knots in southern Georgia Strait. Boats commonly drag anchor and may go aground during these conditions.
The two offshore mooring buoys are in service year-round. Please observe mooring limitations posted on the buoys and at the onshore bulletin boards. Moorage fees are required from 1 p.m. to 8 a.m. Boaters must register and pay moorage onshore at the pay station.

Archaeological sites indicate Native Americans used the island for thousands of years as a shellfish harvesting site. Europeans first discovered the island during the late 1700s when the Spanish Elisa Expedition surveyed the area. The island was named Patos Island which is Spanish for duck. Alcid sea birds, sometimes referred to as ducks, are abundant in the area. A rock formation in the small east cove near Toe Point is shaped like a duck's head.
In the 1890s, a lighthouse station was established at Alden Point and the existing lighthouse was finished in 1918. The lighthouse station was occupied and operated by Lighthouse Service and the U.S. Coast Guard staff and their families until the late 1960s. Civilian employees then Washington State Parks staff lived and operated the site until it was finally automated in the 1970s. Numerous buildings were constructed at the station over the years, but all facilities except the lighthouse have been razed and burned by the Coast Guard and the Bureau of Land Management (BLM). The last remaining support building, a 1950s duplex residence, was burned on November 18, 2005. The BLM intends to re-establish native flora to the site.
