RV camping at San Juan Islands

The peak Anacortes to Friday Harbor fare for a vehicle under 30 ft over 7'2" is $256.75 one way. The median Seattle rental is $199.95 per night.

Price the crossing before the rental on any San Juans trip, and stay longer to amortise it. A two-night San Juans trip spends more on the ferry than on the vehicle.
