Ferries to the San Juan Islands depart from Anacortes, which is a 2-2.5 hour drive north of SeaTac airport.
You can drive onto the ferry or park at the Anacortes Ferry Terminal and walk on. If you plan on driving your car onto the ferry, reservations are required! You will need to make reservations for both your arrival and departure trips. Reservations are not required for walk-on-only passengers (so you don’t need to reserve if you plan to take a shuttle from Seattle to the ferry terminal)
The ferry reservation system on the WSF website is complicated, so we will try to break it down for you:
To get to the island, you will need to drive from Seattle to Anacortes (~2 hr drive, depending on traffic). From Anacortes, you will take a ferry to Friday Harbor (the main town on San Juan Island). Don’t reserve a ferry to Orcas, Lopez, or Shaw island and expect to be able to get to San Juan Island from there… the islands are not connected by a bridge and you can only get between them by ferry!
Ferry reservations are released in 3 waves, with 1/3 of reservations released in each wave:
1st wave: Tuesday, May 3rd at 7am PDT. All summer reservations open. We recommend setting an alarm and booking as soon as the site opens.
2nd wave: 2 weeks before the sailing date at 7am PDT. If you miss the first wave and plan to travel to the island on Wednesday, June 19 then set an alarm for 7am on Wednesday June 15. If you plan to leave the island on Friday, July 1 then set an alarm for 7am on Friday, June 17.
3rd wave: 2 days before the sailing date at 7am PDT - by this point, usually only the very early or very late boats for any given day are available, so we don’t recommend waiting. Those last reservations usually sell out by 7:15am, so set an alarm!
Remember that you need to make reservations for your travel to and from the island!
If you aren’t sure of your dates or aren’t sure if you are going to bring a car, then we recommend booking anyway. There is no charge when booking a ferry reservation but you will be charged a “no show” fee of $10 if you book a reservation and then don’t use it or cancel it. You can cancel your reservation up until 5pm the day before your travel date.
