McCall to Friday Harbor Road Trip Guide

The route from McCall, Idaho to Friday Harbor, Washington crosses the longest floating bridge in the world—the Lacey V. Murrow Memorial Bridge on I-90 across Lake Washington. This 21-mile lake crossing sits at the tail end of a 620-mile journey that starts at 5,020 feet elevation in the Payette National Forest and ends at sea level in the San Juan Islands. The drive typically takes 10-11 hours without stops, but the best stops McCall, ID to Friday Harbor, WA demand at least three days to absorb the Columbia River Gorge, the Cascades, and the Olympic Peninsula ferry ride.

How long to drive McCall, ID to Friday Harbor, WA? The shortest route via US-95, I-90, and WA-20 covers 620 miles and takes about 11 hours of pure driving, but factoring in the Anacortes ferry (up to 1.5 hours wait) and must-see detours, budget a full day for the ferry crossing and two days on the road. Is it worth driving McCall, ID to Friday Harbor, WA? Absolutely—this route passes through eight distinct biomes, from high desert pine forest to temperate rainforest to saltwater archipelago.

Use how to find the best stops and hidden gems between cities to plan spontaneous detours and avoid tourist traps.

I-90 has excellent safety standards (wide shoulders, guardrails, and emergency phones every mile). However, US-95 north of McCall is a two-lane highway with limited lighting—drive with headlights on, even at dusk. Deer and elk crossings are common at dawn and dusk near the Cascade crest.

Fatigue management: Plan rest stops every 2 hours. The Wild Horses Monument in Vantage, WA (mile 440) offers a free pull-off with 18 life-sized horse sculptures and a panoramic view of the Columbia River. Another great stop is the Gingko Petrified Forest Interpretive Trail near Vantage (mile 445)—a 1-mile loop through petrified wood.

Family and child suitability: The route is highly family-friendly. The Children’s Museum in Yakima (mile 330) has interactive exhibits on agriculture. At the Anacortes Ferry Terminal, kids can watch sea lions from the dock while waiting for boarding. Pet-friendly framework: Most state parks (like Bridle Trails near Seattle) allow leashed dogs on trails. The ferry allows pets in vehicles and on outer decks (must be leashed). Some hotels in Friday Harbor welcome pets, such as the Earthbox Inn.

Hidden off-route spots: 30 minutes south of I-90 near Ellensburg, the Olmstead Place State Park preserves a 1875 homestead with original log cabins. Another gem: the Leavenworth Nutcracker Museum (US-2 detour) houses 7,000 nutcrackers from 60 countries.

Fuel economy varies dramatically: from McCall (elev. 5,020 ft) to the Columbia River (elev. 400 ft), expect 20-22 mpg in a sedan climbing passes. Once on I-90, flat cruising yields 27-30 mpg. Gas stations cluster every 20-30 miles on I-90 but thin out on US-95 north of McCall—fill up in Grangeville, ID (mile 80). Toll roads? None. But the Washington State Ferry from Anacortes to Friday Harbor charges $55 round trip for a standard vehicle (reservations recommended).

• Road conditions: I-90 is well-maintained year-round; US-95 has winter ice. Ferry cancellations occur in high winds (October–March).
