Oregon’s Pacific Coast Highway 101, road-tested for the Astoria–Tillamook stretch

Between the Columbia River and Tillamook Bay, US 101 flips from quick coastal straights to tight headlands and town main streets that can eat an hour if you mistime lights and viewpoints. If you’re plotting a Portland-to-coast loop or threading a weekend north or south along the Oregon Coast, the direction you choose matters more than it does inland. Ocean-side pullouts, parking angles, and left-turn hassles change your day’s rhythm, and so do the places where the highway narrows and everyone slows to look at the water. This page exists to point you straight at the guidance that helps you pick a direction, set a realistic clock, and make your stops without turning a short hop into an all-day crawl.

You’ll find one focused piece here, written for this exact corridor. It compares the experience of running northbound versus southbound and shows how that choice affects where you can easily pull off, how long you should expect to linger, and where momentum slips away. Use it to decide which way to run before you lock in lodging or lunch times.
