- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Blake Island is a 192-hectare marine state park in Puget Sound, about 13 km from downtown Seattle as the crow flies but reachable only by water. It has 8 km of saltwater shoreline, second-growth forest, a first-come moorage and campground, and a beach that is part of an underwater park. The Suquamish used it as a camping ground and it is widely described as the birthplace of Chief Seattle, though that is disputed. There is no lodge and no restaurant: you bring food, or you eat on the boat.

- Campsites are first-come

- Shells and driftwood stay
- Take out anything artificial you find, but leave shells, driftwood and living creatures in place.
- Seal pups
- Do not approach hauled-out seals or pups; keep children and dogs well back.
- Whale distance
- Stay 200 yards (about 180 m) from orcas and keep out of their path — a federal rule for all vessels in inland Washington waters.

Accessibility
- The dock, ranger office, restrooms and one campground restroom are accessible; the island is reached by boat, so boarding is the main barrier.
- The Perimeter Road is an unimproved dirt trail over bluffs and is not suitable for wheelchairs or strollers.
- The nature trail near the campground is the easiest walking on the island.
Visiting lightly
- Pack out everything, including food scraps; there is no rubbish service for day visitors.
- Do not take shells, driftwood, sea stars or crabs from the beach — the tidelands are a protected underwater park.
- Keep 200 yards from orcas and leave hauled-out seals alone; disturbance is the main risk to both.
- Camp and moor midweek in summer to spread pressure on the 44 sites and 24 buoys.
Questions people ask
How much does it cost to enter Blake Island?
There is no entry fee and no gate — you arrive by water. Your real costs are transport and moorage: the Blake Island Shuttle from Bainbridge Island is about US$125 per person round trip with a two-person minimum, a campsite is US$22–37 per night depending on season and utility, primitive and water-trail sites are US$12, and shore power at the dock is about US$6 per night. Moorage itself is first-come and the fee is set by Washington State Parks (check).
What are the best hikes in Blake Island?
The Perimeter Road is the main walk: about 7 km on an unimproved trail over the bluffs above the beach, taking 2.5–3 hours, with views to the Olympic Mountains and the Seattle skyline. The nature trail near the campground is a 30-minute marked loop. Beach walking is the third option, but parts of the south and west shore are difficult or impassable at high tide, so check the tide table.
When is the best time to visit Blake Island?
Mid-May to early September for dry, mild weather and long days, with May and September the sweet spot before and after the summer rush. July and August are warmest but the 24 buoys and dock space fill quickly. Winter is drizzly, dark and quiet; the island is open year-round but boats are few.
How do you get to Blake Island?
Only by boat. The Blake Island Shuttle runs from Eagle Harbor on Bainbridge Island, typically leaving in the morning and returning the same evening or the next morning. Private boats and kayaks launch from Manchester, about 3 km away, which is the closest put-in. There is no ferry from Seattle and no bridge.
Can you camp on Blake Island?
Yes. The main campground has 44 standard sites, two primitive sites and three water-trail sites for kayakers, all first-come, first-served, with a maximum of eight people per site. There are restrooms, one shower area and potable water in some areas. A group site for up to 50 people is the only reservable option.
Is there food or lodging on Blake Island?
No lodging beyond camping and sleeping on your boat. A small park store at the ranger office sells snacks, sodas, charcoal and firelogs, but you should bring your own food and water. Potable water is available in some camping and moorage areas.
