Harbour

Forested island of 476 acres in Puget Sound, about 8 nm west of downtown Seattle, run as a marine state park with no road or ferry access.

Guide

Approach and anchoring

Approach from the east across Puget Sound. The state park dock on the north side offers 1,500 feet of moorage with shore power; 24 mooring buoys lie off the same shore. Boats over 45 feet must use the dock rather than the buoys. Three-night limit and first-come, first-served.

Practical

Buoy moorage 23 USD per night, dock moorage 1 USD per vessel foot. No fuel berth on the island. Bainbridge Island and Eagle Harbor marinas sit 4.6 nm north for diesel and supplies.

Ashore

Five miles of beach and a network of forest trails cross the island. The Tillicum Village longhouse, built in 1961 by caterer Bill Hewitt and used for Coast Salish salmon bakes, sits a short walk from the dock; tour boat service ended in 2021.

History

Suquamish ancestral camping ground, named in 1841 by Lt. Charles Wilkes for George Smith Blake of the United States Coast Survey. Bought around 1900 by attorney William Pitt Trimble, then set aside as a state park in 1959.
