History of the Area
The island was named by the Wilkes Expedition in 1841 in honor of Frederick D. Stuart, the captain's clerk on the expedition. The park was acquired in four transactions between 1952 and 1975 by purchases from the Bureau of Land Management, the U.S. Coast Guard and the Washington Department of Natural Resources.

Located in San Juan County.

The park is reachable only by boat. The nearest access is four miles southeast at Roche Harbor Resort on San Juan Island. The entrance to Reid Harbor is partially blocked by two small islands. Boaters should keep these islands to their starboard when entering the harbor.

The entrance to Prevost Harbor is gained by passing around either end of Satellite Island.
