Sequim to Tillamook Road Trip: Best Stops, Costs & Scenic Views

Before you start the engine, know this: the route from Sequim, WA to Tillamook, OR crosses the mouth of the Columbia River via the Astoria-Megler Bridge, the longest continuous truss bridge in North America at 4.1 miles. With an anchor date of 1966, it's a signature crossing that sets the tone for the drive.

This guide covers everything from driving time to hidden stops, costs, climate, and family-friendly considerations—each fact appears exactly once. For a deeper strategy on finding under-the-radar attractions, see my guide on how to find the best stops and hidden gems between cities.

The fastest path uses US-101 south to Olympia, then I-5 to Portland, then US-26 west to the coast. Expect tolls on the Tacoma Narrows Bridge ($5.50 each way) and on I-5 through Portland (no toll, but congestion).

• Fuel economy: A typical car gets 30 mpg; gas prices around $4.50/gallon (mid-2025) put total fuel cost at roughly $36–$45.
• Road quality: Well-maintained; the Oregon coast section has occasional hairpins and narrow shoulders.
• UNESCO site: Fort Vancouver National Historic Site, a UNESCO World Heritage Site (since 2021), is a short detour near Vancouver, WA.
• Free ferry: The Wahkiakum County Ferry (no toll) operates across the Columbia River between Cathlamet, WA and Westport, OR—a scenic alternative.

From the rain shadow of the Olympic Peninsula (Sequim gets only 16 inches of rain annually) to the lush, rain-soaked Oregon coast, the climate shift is stark. The drive moves from alpine forests to sandy dunes and rugged headlands.

Key stops include the Columbia River Maritime Museum in Astoria (entry $16), Cannon Beach with its iconic Haystack Rock, and the Tillamook Creamery, where you can sample cheese and ice cream.

Hidden off-route spots include the Astoria Column (a 125-foot tower with murals, view of the river, and a model plane), and the quaint town of Chehalis, known for its historic depot. For a quirky stop, the World's Largest Frying Pan in Long Beach, WA is a photo op.

Infrastructure safety is high; the route is largely freeway and well-signed. Note that the Astoria-Megler Bridge has no emergency lanes—use pull-offs if needed. Winter driving can be tricky over the Coast Range, but the majority of the year is benign.

Rest areas are plentiful: one in Washington near Chehalis and several in Oregon along US-26. For fatigue management, take a break every 2 hours; recommended stops include the Cathlamet waterfront and the Sauvie Island Rest Area.

Family-friendly: The Children's Museum in Astoria and the Tillamook County Pioneer Museum offer kid-focused exhibits. For pets, most coastal beaches are leash-friendly, and both Fort Stevens State Park and Cape Lookout State Park allow dogs on trails.

Local commerce and culture: Sequim is known for its lavender farms (the Sequim Lavender Festival is every July), and Tillamook is home to the famous cheese factory. Along the way, you'll pass through towns like Aberdeen and Seaside, each with its own character.
