Blake Island State Park in Washington, USA - map and visitor information

Research checked: 2026-10-29. Check linked official notices before travel.

Blake Island Marine State Park is a boat-only Washington State Parks destination in Puget Sound. Arrange your water transport before planning a hike, picnic, or camping stay. A campsite reservation does not secure moorage, and winter visitors must plan for the campground water shutoff.

An island outing close to Seattle

Wooded trails and shoreline recreation give the island a different rhythm from the mainland. The practical choice comes first: visit by your own boat or suitable paddlecraft, then decide whether to return that day or stay overnight. There is no road connection to the park.

Know before you go

Fees, hours, and seasonal access

Prepare for a marine crossing

Wear a life jacket. Cold-water shock and loss of swimming ability can occur before hypothermia, even when the air feels warm. Read Washington State Parks' cold-water guidance before a boat or paddling trip.

Choose a route and vessel that match your skills and the marine conditions. Check the weather before and during the trip, carry a whistle and emergency communication equipment, and leave a float plan with someone ashore. The agency's paddling guidance explains preparation for open waterways.

Pack everything out

The island has no trash receptacles. Carry all rubbish back with you. Dogs must remain on leash, horses are prohibited, and metal detecting is not allowed. Use only designated fire areas and follow the current fire restrictions.

Camping and moorage are separate

Use the reservation link on the official park page for reservable campsites and the group camp. Standard sites allow up to eight people in the main campground and six at the west end. The reservable group camp operates all year for up to 50 people.

Moorage is first come, first served and limited to three consecutive nights. A camping reservation does not guarantee a dock or buoy. Buoys allow one boat with no rafting. Boats longer than 45 feet must use the dock, and shorter boats must follow the length limit posted on each buoy.

Maps, location, and boat access

The park is an island in Puget Sound near Seattle. Its PO Box 338, Manchester, WA 98353 address is a mailing address, not a road entrance. Use the maps and visitor guides on the official park page while planning your boat arrival.

Nearby mainland parks

These are alternatives on the Kitsap mainland after a boat transfer, not stops reached by driving from the island.

• Manchester State Park has road access at 7767 East Hilldale Road near Port Orchard.
• Illahee State Park has road access at 3540 Northeast Sylvan Way in Bremerton. Its Beach Trail is closed for maintenance until further notice.

Explore on foot or stay by the shore

Walk the wooded trails after landing, explore the beaches, or use a picnic shelter. Two shelters can be reserved and have no electricity. Camping extends the visit, but water transport and moorage still need separate planning.

The three Cascadia Marine Trail campsites on the west side are reserved for arrivals by human- or wind-powered watercraft. They are not standard motorboat camping sites.

Island facilities and winter limits

The park lists a ranger station, restrooms, showers, and drinking water among its amenities. Campground water shuts off from early November through March, so confirm the facilities available for your dates and bring the water you need. The boat pumpout is unavailable. Picnic shelters have no electricity, while dock electricity carries a daily charge.

About the island

Forest, meadows, and rocky saltwater beaches form the island's setting. The water crossing is part of the visit, rather than a short approach from a parking lot.

Coast Salish territory and later tourism

The island lies within traditional Coast Salish territory. Present-day descendants include members of the Suquamish Tribe and Muckleshoot Indian Tribe. The park's history account also records the end of the Tillicum Village concession in 2021. Do not plan around the former dining excursion.

Island habitats

Woodland and meadow meet the saltwater shoreline here. A trail walk and a beach visit provide different ways to look at the island's habitats without disturbing them.
