Blake Island State Park is in the Puget Sound region of Washington of United States. Blake Island State Park is a 475-acre marine camping park with five miles of saltwater beach shoreline providing magnificent views of the Olympic Mountains and the Seattle skyline. The park is only reachable by tour boat or private boat.
Blake Island is unusual in that it is wild and well-preserved, yet it lies in Puget Sound approximately 8 miles from the major urban center of downtown Seattle. It is in east central Kitsap County, 4 miles off Alki Point, between the south end of Bainbridge Island and the north end of Vashon Island. A boat launch in Manchester is the closest access to the island.
Blake Island was used as a camping ground by the Suquamish tribe. It is widely understood to be the birthplace of Chief Seattle, for whom the city of Seattle was named (although there are several different theories about his birthplace). The island was first noted by British explorer George Vancouver in 1792, as part of his exploration of Puget Sound, though it was not named.
In 1841, Lt. Charles Wilkes of the United States Exploring Expedition named it Blake Island for George Smith Blake, the officer in charge of the United States Coast Survey between 1837 and 1848, although it was known locally as Smuggler's Island for some time. In the mid-19th century, the island was logged for its timber.
During Prohibition, it was frequently used as a refuge for bootleggers smuggling alcohol from Canada.
William Pitt Trimble, a Seattle millionaire, purchased Blake island, and renamed it Trimble Island for a time. By 1917 he and his family lived there in a magnificent estate.
The Trimble family invited Camp Fire Girls from Seattle and throughout Washington State to hold their first summer resident camp on Trimble Island, in 1920. The girls named their camp, Camp Sealth, in honor of the birthplace of Chief Seattle (also known as Chief Sealth). They paid for a delivery of logs, which began floating away at high tide. They scrambled to haul them back, and soon found themselves dealing with a fire on the island. Due to other plans by the Trimble Family, Camp Fire Girls of Seattle searched for a new, and permanent location for Camp Sealth. By the next summer the camp was moved to Vashon Island, where it remains today.
In 1929, the Trimble family's occupation of the island came to an end when William Trimble's wife Cassandra drowned in a tragic automobile accident in Seattle. After that, the island was abandoned and the house was left to decay. Trimble sold Blake Island to an investment company in 1936, and retired in Seattle.
During World War II, a unit of the Coastal Artillery of the US Army was garrisoned in the Trimble mansion. The mansion burned during this time, leaving only the foundations visible today. It wasn't until 2008 that a 76-year-old retired gas station owner admitted that he and his friend accidentally set fire to the mansion as teenagers when trying to keep warm after swamping their boat in a storm.
In 1959, the state of Washington made the entire island a state park.
Blake Island has 5 miles of saltwater beach shoreline. The tidelands and bedlands make an underwater park.
Flora and fauna
Like most of the islands in Puget Sound, Blake was heavily logged in the 19th century, but it now has an extensive second-growth cedar, douglas fir, hemlock, spruce, yew, alder, cherry, maple and other flora and fauna common to the Pacific Northwest. Daisy, foxglove, a wide variety of wild berries, ferns, mosses, lichens and thistle can also be found on the island.
Deer, raccoons, squirrels, chipmunks, otters and mink call the island home while many types of birds migrate through the area. Sea life is typical for Puget Sound: there are many types of clams, oysters and barnacles, mussels and even geoducks. Various types of sea stars are common along with the many types of crabs that hide under rocks at low tide.
It is generally warm and sunny during the summers and mild and drizzly in the winters. It can be rainy (but is usually just drizzly) on any given day. It can also be sunny and pleasant in January. Mid-June through early September is often sunny. The record high in nearby Seattle is 103°F (39°C); the record low is 0°F (-18°C). The warmest months are July and August, with average highs in the high 70s (about 25°C), though often having days in the 80s and even 90s (32°C). The coldest month is January, with average lows in the mid-upper 30s (about 3°C), although occasionally can get cold, especially when it is not cloudy. The dark, short, and overcast winter days can be unpleasant and depressing to some, although the bright side is that they are not as cold as the latitude (47.6 °N) might lead you to think. The summer, however, is very pleasant. Temperatures are very mild. The days are also very long, and sunset (let alone twilight) is after 9PM for weeks. Also, the vast majority of days in the summer have no rain. The main challenge of Blake Island's weather is more the overcast skies than the rain. If you come in the summer, you should see plenty of sunny weather.
Blake Island State Park has 24 mooring buoys and 1,500 feet of dock space which is all on a first-come, first-served basis. Because of the island's proximity to major urban centers, they fill up quickly in the popular summer months. If you are on the dock, don't be surprised if another boat asks to raft off of your boat. Electricity is available for $6 per night and there is a pumpout station. There are also restrooms and showers provided on the island.

The longest trail, 4½ miles, circumnavigates the island on the bluffs above the beach and takes about 2½ hours walking on an unimproved trail. Additionally, there is a nature trail with markers pointing out the assorted native flora which takes about half an hour to explore. Or explore along the miles of beach, but be aware of posted tidal conditions as some areas are difficult or impassible at high tide. The state provides a PDF map of the island including trails.
Blake Island offers miles of thickly wooded trails interspused with wide open views of Puget Sound, the Cascade and Olympic mountain ranges and even views of downtown Seattle.
Beachcombing is hugely popular on Blake Island, however due to its size and relatively difficult to reach location it is easy to find your own isolated patch to explore.
Created by glaciers, Blake Island offers amazing scenery as the clear waters play against wild coastlines and snow peaked mountains and views of downtown Seattle scatter on the horizons. There are popular picnic areas or letting the kids play in the sand or the more adventurous could head around the island beaches which range from the rugged to the sandy smooth. Small crabs, moon snails, sea stars and sand dollars are common sites and tide pools can offer hours of exploration.
Seashells and driftwood are considered part of the natural environment and should not be removed, however the often rocky and wild shores are havens for creating and revealing beach glass and anything artificial found is fair game for removal. Be gentle with sea creatures and keep a wide distance away from nesting birds, seals and other shore animals and always put back anything removed from the shoreline.
The Kitsap Audubon Society has been meeting since 1972 and has a broad coalition of birders tracking and sharing sightings. (Blake Island is in Kitsap County). They also maintain an active website with updates of the latest sightings, suggestions on areas for birders, and a regular newsletter. They also developed a checklist of birds likely to be seen in the area.
Sea kayaking can be a rewarding way to explore the area around Blake Island, allowing the paddler a closer and slower look at their surroundings. Blake Island is especially popular because of its proximity to urban launch areas. Thick forests of majestic pine and deciduous trees and dozens of creeks and estuaries dot the coastline. Harbor Seals, otters, Sea Lions, Bald Eagles and Blue Herons are common sites while the occasional viewing of an Orca or Grey Whale is not out of the question.
Organized trails offer overnight camping options and maps of appropriate lengths and scenic travel destinations.
- Cascadia Marine Trail. This inland sea trail is a National Recreation Trail and designated one of only 16 National Millennium Trails by the White House. Suitable for day or multi-day trips, the Cascadia Marine Trail has over 50 campsites to visit including Blake Island.

Scuba diving the cold waters of Puget Sound takes a bit more gear and training than in warm water locations, but the rewards are incredible. The area contains some of the best diving in the world and many dive sites are completely covered with colorful sea creatures that defy description. The famous underwater explorer Jacques Cousteau named Puget Sound as his second favorite diving area in the world. The state has offers a guide to parks with launch sites here which includes Blake Island.
- Blake Island Reef. Comprised of a long series of cement chunks that run parallel to the southern shore of Blake Island. This artificial reef structure runs east to west from 50-60ft with the most dynamic debris toward the center of the southern shore. The site receives little scuba traffic and you can expect to see many large or interesting creatures among the debris such as wolf eels, Giant Pacific Octopus, lingcod, rockfish, sea cucumbers, sea lions, and loads of nudibranchs.
Blake Island is an excellent place to launch a boat to search out the elusive and meaty Dungeness Crab, but other less popular crabs are plentiful in the area. Crab season starts with a two-day opener July 1st and 2nd and follows up with crabbing every Thursday through Monday through Labor Day weekend. A wide array of crab traps are available from a variety of area sporting goods stores and the red and white buoys marking the traps are a common site on the water during the short crabbing season. Fishing permits are required and can be purchased from a variety of local stores, more information is available from the Washington Dept of Fishing and Wildlife.

Though many of the animals in the area are used to seeing humans, the wildlife is nonetheless wild and should not be fed or disturbed. Stay at least 25 m from all wild animals. Check trailhead postings at parks for recent activity and be aware of rules keeping a distance from Orca Whales and other marine animals while boating. Regulations for killer whales require that boaters stay 200 yards away & keep path of the whales clear. These new U.S. regulations apply to all vessels (with some exceptions) in inland waters of Washington.
Don't disturb resting seal pups, keep children and dogs away and report to the local stranding hotline +1 253 589-7235. Seal pups 'haul out' to get much-needed rest when they are young and are often alone for many hours. They are extremely vulnerable at this time and should be left alone. Only about 50% of Puget Sound seal pups make it through their first year so please help to protect their health.
