Washington State Ferries is the largest ferry system in the United States by ridership, and for visitors it's often as much a scenic experience as a practical crossing — cutting across Puget Sound to Bainbridge Island, out to the San Juans, or over to the Olympic Peninsula, with the Seattle skyline and the Olympic Mountains often visible from the deck.
Seattle to Bainbridge Island
The most popular route for visitors runs from Colman Dock in downtown Seattle to Bainbridge Island, a crossing of around 35 minutes that's genuinely one of the best short, cheap scenic trips in the Pacific North-West — the classic postcard shot of the Seattle skyline from the water is taken from this ferry. It's a popular round trip in its own right: ride across, spend a little time in Bainbridge's small waterfront town, and ride back, all without needing a car.
Seattle also has a separate route to Bremerton, further down the Kitsap Peninsula, useful if you're headed that way rather than Bainbridge, and slightly longer at around an hour.
Walk-on versus bringing a car
Most of Washington State Ferries' Puget Sound routes, including Seattle–Bainbridge, carry both vehicles and walk-on foot passengers, and for a visitor without a specific reason to bring a car across, walking on is almost always the simpler choice. Foot passengers board quickly through the terminal without needing to queue in a vehicle line, and fares are lower than for a car. If you do need a vehicle on the other side — heading further out into the Olympic Peninsula or touring several San Juan islands, for example — bringing a car is worth the extra cost and the vehicle queue.
The San Juan Islands
The San Juan Islands route doesn't depart from Seattle at all — it runs from Anacortes, around two hours' drive north of the city, calling at Lopez, Orcas and Shaw islands before reaching Friday Harbor on San Juan Island, with a seasonal extension to Sidney, British Columbia. This is a genuinely different trip from the Bainbridge crossing: longer, more spread out, and popular with visitors touring multiple islands over several days rather than a quick there-and-back.
Vehicle space on the San Juan Islands route is limited and popular sailings, especially summer weekends, can fill up — this is one of the routes where a vehicle reservation genuinely matters. Book ahead through Washington State Ferries' reservation system if you're bringing a car in high season; walk-on passengers generally don't need to reserve, since foot-passenger capacity is far less constrained.
Reservations: when you need one and when you don't
Reservation requirements vary by route. Seattle–Bainbridge and Seattle–Bremerton generally operate first-come, first-served for vehicles, with no reservation system — arrive early for popular sailings, particularly Friday evenings and weekends in summer, when the vehicle line can mean waiting for a later boat. The San Juan Islands routes and the international run to Sidney, BC, do use advance vehicle reservations for at least part of their capacity, and booking ahead is strongly advised in the busy summer season. Always check the current system for your specific route before travelling, since policies are adjusted from season to season.
Paying and boarding
Fares can be paid at the tollbooth by card or cash, and an ORCA card — the regional transit card used across the Seattle area — works for walk-on fares on many routes too, useful if you're already using it for Seattle's buses and light rail during your trip. Vehicle lanes are clearly marked at each terminal, and walk-on passengers use a separate, faster-moving line through the terminal building.
Combining a ferry with the rest of a Pacific North-West trip
Washington State Ferries fits naturally alongside a wider regional itinerary. If you're arriving in Seattle by air, see our guide to Seattle Airport to the city for the Link light rail into downtown, close to Colman Dock. If you're continuing north into Canada, our guide to Seattle to Vancouver covers the Amtrak Cascades rail alternative, and BC Ferries covers the equivalent Canadian system serving Vancouver Island and the Gulf Islands, worth comparing if your trip crosses the border by water at some point. A drive to Mount Rainier is also a popular add-on for visitors based in Seattle — see Seattle to Mount Rainier for that separate, road-only trip. Travellers heading down the coast afterwards might also compare against the Coast Starlight guide, Amtrak's scenic rail alternative from Seattle to Los Angeles.
Weather and seasonal notes
Puget Sound crossings run year-round and are rarely cancelled outright, though fog, particularly in the shoulder seasons, can cause delays. Summer is by far the busiest season for both the Bainbridge and San Juan routes, with the longest vehicle queues and the highest chance of a sailing being full — travelling as a walk-on passenger, or simply allowing extra time and an earlier arrival at the terminal, avoids most of the stress this causes for first-time visitors.
Which option should you choose?
For a quick, scenic taste of Puget Sound from Seattle, the Bainbridge Island round trip as a walk-on passenger is hard to beat — cheap, frequent, and requiring no reservation. For the San Juan Islands, plan further ahead: decide whether you need a car, and if so, book your vehicle reservation for peak summer sailings well in advance.
Frequently asked questions
Do I need a reservation for the Seattle to Bainbridge Island ferry?
No, this route generally runs first-come, first-served for vehicles and walk-on passengers, though arriving early for busy evening and weekend sailings avoids a long vehicle queue.
Do I need a car to visit the San Juan Islands by ferry?
Not necessarily — walk-on passengers can explore Friday Harbor and the islands' main towns without a vehicle. A car is worth bringing only if you plan to cover more ground across multiple islands, in which case book a vehicle reservation ahead for summer sailings.
Does the Seattle to Bainbridge ferry depart from downtown Seattle?
Yes, from Colman Dock on the downtown Seattle waterfront, an easy walk or short ride from the Link light rail and most downtown hotels.
Can I use an ORCA card on Washington State Ferries?
Yes, on many routes an ORCA card can be used to pay walk-on fares, the same card used across Seattle's buses and light rail network.
