Seattle to Friday Harbor Road Trip Guide: Ferries and Fjords

This route to Friday Harbor is unique because you drive onto a ferry that becomes part of the highway. The Washington State Ferries system treats SR 20 as a marine highway, with scheduled sailings from Anacortes to Friday Harbor.

The drive from Seattle to the Anacortes ferry terminal is about 80 miles north on I-5, then west on SR 20. Including ferry time (roughly 1.5 hours to Friday Harbor), the total journey takes 3.5 to 4.5 hours depending on waits.

A lesser-known fact: the ferry route passes through the Wasp Islands, a cluster of rocky islets that belong to the San Juan Islands National Monument. Keep an eye out for harbor seals basking on the rocks.

Infrastructure Safety and Road Quality

I-5 and SR 20 are well-maintained. The Deception Pass Bridge has a 30 mph curve and no shoulder. Ferry queuing is safe but requires patience.

• Check WSDOT alerts for construction or delays.
• Watch for deer on San Juan Island, especially at dawn/dusk.
• Cell service is intermittent on the ferry and some island roads; download offline maps.

Family and Child Suitability

The ferry ride is a highlight for kids; they can watch for whales and seals. Many parks have playgrounds.

• Recommended: Deception Pass State Park (nature center, hiking trails).
• Lime Kiln Point: Family-friendly picnic area with ranger talks.
• Friday Harbor's marina: Ice cream shops, playground, and a free carousel.

Pet-Friendly Framework

Pets are allowed on ferries (inside vehicle or on deck on leash). Many accommodations and restaurants welcome dogs.
