Stuart Island Marine State Park

Stuart Island Marine State Park is a 8-acre marine park in San Juan County, about 13 miles northwest of Friday Harbor.

Things to do include surfing, historic sites, canoeing and kayaking, boating, and swimming. Facilities for water recreation include a swimming beach. Overnight options include campsites, with tent sites.

Camping information The park has 14 primitive campsites and four marine trail sites. Camping is available on a first-come, first-served basis. Most sites are located on Prevost Harbor or on the ridge that separates Prevost and Reid harbors. Cascadia Marine Trail camp sites Campsites 15-18 at the head of Reid Harbor are designated Cascadia Marine Trail sites and are for the exclusive use of those arriving by human- or wind-powered watercraft.

Boating There are 20 buoys and 448 feet of dock, as well as a pumpout station. Additionally, you can find plenty of good anchorages along the entire length of the harbor. Please respect the private buoys, docks and property surrounding the park. All boats, including boats rafted to another boat, must self-register and pay moorage fees upon arrival. Moorage fees are charged year round for mooring at docks, floats and buoys from 1 p.m. to 8 a.m. Daily and annual permits are available. Boat pumpout This facility is located on a barge, open year-round, 24 hours a day with a floating dock. There are two slips available for pumpout usage. Access to this pumpout is limited to vessels with a length of no more than 60 feet. There is a stationary pumpout located at Reid Harbor. This facility also has a portable toilet dump station located at the Reid Harbor barge. The pumpout is located at Latitude: 48° 40' 28.90" N (48.6747) Longitude: 123° 11' 55.87" W (-123.1989).

Unless arriving by kayak, boaters should not attempt to enter Prevost Harbor at the east end. This entrance is full of rocks and reefs. The only safe entrance is at the west end of Satellite Island. Stay in the middle of the channel and harbor until you are adjacent to the park dock. Consult your charts before you arrive. Once inside Prevost Harbor, there are plenty of deep water anchorages available if the park buoys and dock are full. Drinking Water is available May through September. No garbage services on the island, practice Leave No Trace principles. Read our blog to learn more about the LNT principles.
