Quick Answer
The best overall way to get from Seattle-Tacoma International Airport (SEA) to the Bainbridge Island Ferry Terminal is a pre-booked shared shuttle or rideshare (Uber/Lyft) directly to Seattle's Colman Dock, followed by the Washington State Ferry. This balances cost, convenience, and time. The total trip takes 60-90 minutes and costs $45-$80 per person (shuttle + ferry fare). The cheapest way ($16) uses the Link Light Rail + Bus #55, but takes over 2 hours. The fastest way (60 min) is a direct taxi or private car, but costs $100+.
Shuttle & Direct Van Services
Pre-booked shuttle services offer a direct, hassle-free transfer from Sea-Tac baggage claim to the ferry terminal entrance at Colman Dock. This is the most recommended option for travelers with luggage, families, or those seeking a guaranteed schedule without the surge pricing of rideshares.
| Provider | Service Type | Approx. Cost (to Colman Dock) | Travel Time | Key Feature |
|---|---|---|---|---|
| ShuttleExpress | Shared Van / Private | $35-$55 (shared) / $90+ (private) | 45-60 min | Door-to-door, meet & greet, book online |
| Quick Shuttle* | Scheduled Coach | ~$30 (with ferry combo) | 60-75 min | Direct to ferry, limited daily schedules |
| Hotel Shuttles | Complimentary (for guests) | Free | Varies | To downtown hotels; then short taxi to ferry |
*Verify current routes as services may change.
How to Book & What to Expect
Book online at least 24 hours in advance for best rates. After claiming baggage, call the provider or proceed to the Ground Transportation desk on the baggage claim level. The van will drop you at the Colman Dock walk-on entrance. Pro Tip: Some companies offer a "Ferry Fast Pass" combo that includes your shuttle fare and pre-paid ferry ticket, saving time at the terminal.
Who It's Best For
- Travelers with more than one suitcase or bulky items.
- Groups of 3-4 people (can be more cost-effective than multiple rideshares).
- Those arriving during peak traffic or bad weather (reliable and covered).

- Transfer to Bus: Exit Westlake Station and walk 2 blocks to the bus stop at 3rd Avenue & Pine Street. Board King County Metro Bus #55 (direction: West Seattle). Get off at the stop called "Alaskan Way & Marion St", right across from Colman Dock. Ride time: ~10 minutes. Fare: $2.75 (free transfer within 2 hours with ORCA).

Rental Car & Driving onto the Ferry
Renting a car is only advisable if you need a vehicle on Bainbridge Island for an extended stay. For simply reaching the island, it's often the most expensive and stressful option due to Seattle traffic, parking, and ferry vehicle wait times.
The Complete Cost Reality
- Rental Car: $60 - $120+/day (from Sea-Tac).
- Ferry Fare (Car & Driver): $22.25 (One-way from Seattle to Bainbridge). Additional passengers are $9.70 each.
- Gas & Tolls: ~$10-15.
- Downtown Seattle Parking (if you stop): $10-$30/hour.
- Potential Hidden Cost: Long ferry vehicle lines on summer weekends can add 1-2 hours of wait time.
A Smarter Alternative: "Rental Car Drop-Off"
Consider renting a car one-way and dropping it off at a downtown Seattle rental office (e.g., Enterprise on 5th Ave). Then, take a 5-minute taxi or a 15-minute walk to Colman Dock. This avoids the high ferry vehicle fare and the wait in line. Check with rental companies for one-way drop fees.
Driving Directions from Sea-Tac to Colman Dock
1. Take WA-518 W to I-5 N.
2. Follow I-5 N to Exit 164B for US-18 W/WA-99 N toward Alaskan Way.
3. Follow signs for Colman Dock / Washington State Ferries. The entrance to the vehicle holding lanes is on Alaskan Way. Check the ferry wait times before you go.

Traveler Tips & Local Insights
Go beyond the basics with these practical tips from frequent travelers and locals.
1. Mastering the Ferry Experience
- Buy Tickets: Walk-on passengers can buy tickets at automated kiosks or the tollbooth with a card. No need to pre-book as a foot passenger.
- Check the Schedule & Cameras: Always verify the latest schedule on the WSDOT website. Use the terminal webcams to see current vehicle line lengths.
- The 35-Minute Ride: Go to the upper outside decks for stunning views of the Seattle skyline, Mt. Rainier (on clear days), and the Olympic Mountains. The ferry has a cafeteria with basic snacks and drinks.
2. Luggage & Baggage Strategies
If you have heavy bags and are using public transit, consider a luggage storage or shipping service:
- Sea-Tac Baggage Storage: Port of Seattle offers storage at the airport if you want to explore Seattle baggage-free before heading to the ferry.
- Luggage Delivery Services: Companies like LuggageForward can ship your bags directly to your Bainbridge Island accommodation, allowing you to travel with just a daypack.
3. Timing Your Trip
- Avoid Peak Traffic: Weekday rush hours (7-9 AM, 4-6:30 PM) will significantly lengthen any road-based trip from Sea-Tac to downtown.
- Ferry Frequency: Ferries run about every 50-60 minutes during the day, but less frequently late at night. The last sailing is around midnight.
- Summer & Weekend Crowds: From June to September and on sunny weekends, ferry lines for vehicles can be extremely long. As a walk-on passenger, you'll always get on the next boat.
4. Upon Arrival on Bainbridge Island
The ferry terminal on Bainbridge is in the town of Winslow. From here:
- Most downtown Winslow shops, restaurants, and the Waterfront Park are within a 5-10 minute walk.
- For other island locations, call a local taxi (like Bainbridge Island Taxi), use the Kitsap Transit bus system (routes stop at the ferry terminal), or arrange a pickup with your accommodation.
FAQs: Sea-Tac to Bainbridge Island Ferry
What is the fastest way to get from Sea-Tac Airport to the Bainbridge Island Ferry Terminal?
The fastest way is typically by pre-booked private shuttle, taxi, or rideshare (Uber/Lyft) directly to the Seattle Ferry Terminal (Colman Dock), followed by the Washington State Ferry. This door-to-dock option takes approximately 60-90 minutes total, depending on traffic and ferry wait times, as it avoids multiple public transit stops.
What is the cheapest way to travel from SEA to the Bainbridge Ferry?
The cheapest option is combining public transit: take the Link Light Rail from Sea-Tac to Westlake Station ($2.25-$3.25), then walk to the 3rd & Pine bus stop and board King County Metro bus #55 to the ferry terminal ($2.75). Plus the ferry walk-on fare ($9.70). Total cost is under $16 per person, but travel time can be 2+ hours.
Is there a direct shuttle or bus from Sea-Tac Airport to the ferry terminal?
No, there is no single direct bus or shuttle that goes from Sea-Tac Airport to the Bainbridge Island Ferry Terminal. The journey requires a combination of services: either a direct road vehicle (shuttle/taxi) to Colman Dock, or a multi-leg public transit route involving the Light Rail and a connecting bus.
How long is the ferry ride from Seattle to Bainbridge Island?
The Washington State Ferry crossing from Seattle's Colman Dock to Bainbridge Island takes about 35 minutes. Sails frequently, approximately every 50-60 minutes for most of the day. Check the official WSDOT schedule for real-time updates.
I'm arriving late at night (after 11 PM). Can I still get to the ferry?
The last ferry from Seattle to Bainbridge Island typically departs around midnight, but schedules vary. After that, the next sailing isn't until early morning (around 5 AM). If you land late, your only guaranteed option is a taxi, rideshare, or shuttle directly to a Seattle hotel. Overnight parking at the terminal is available if you have a car.
Is it easy to travel with large luggage or a family on this route?
Challenging on public transit due to stairs, crowded trains/buses, and a walk to the ferry. Recommended for families or those with lots of luggage: a pre-booked private shuttle or van service that handles bags door-to-dock. The ferry itself has ample luggage space. Some shuttle companies, like ShuttleExpress, offer family-sized vans.
Should I rent a car at Sea-Tac to drive onto the Bainbridge Ferry?
Only recommended if you need a car on Bainbridge Island. Advantages: convenience and flexibility. Disadvantages: high costs (rental + gas + $22.25 for car & driver ferry fare + Seattle parking/tolls). Ferry vehicle lines can be long, especially on weekends. For just reaching the island, dropping off a rental car in downtown Seattle before walking onto the ferry is often cheaper and faster.
Can I use a multi-day transit pass for this journey?
Partially. An ORCA card covers the Link Light Rail and King County Metro bus. However, the Washington State Ferry fare must be paid separately (ORCA cards are not accepted for vehicle fares, only for multi-ride walk-on passes purchased in advance). You can load an ORCA card at the Sea-Tac station.
