Stuart Island Marine State Park
Friday Harbor, WA 98250
The northwestern-most San Juan Island is sure to inspire with beautiful sunsets that glow orange over clear waters. Come prepared to stay overnight at the primitive campground or sleep on your boat. Once you arrive at this water-access-only gem, you won't want to leave.
Rules
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.
