The San Juans ferry fare falls 26% overnight on 1 October
The peak Washington State Ferries tariff on Anacortes to Friday Harbor ends on 30 September 2026. A vehicle under 30 feet over 7 feet 2 inches pays $256.75 one way on 30 September and $190.40 on 1 October, so departing one day later saves $132.70 round trip.
How this was worked out
WSF fare detail for Anacortes to Friday Harbor on seven travel dates between 20 September and 15 October 2026.
Queried the fare page date by date and narrowed until the price moved, isolating the change to the single overnight step between 30 September and 1 October. WSF does not publish this boundary as a date anywhere.
What to do
Move a shoulder-season San Juans departure to 1 October or later. The sailing, the vessel and the crossing are unchanged.
$132.70 round trip for leaving one day too early, on top of the rental.
