Seattle to Depoe Bay Road Trip: Ultimate Guide

Did you know that US Route 101, which you'll follow much of the way, was originally part of the Oregon Trail and completed in 1926? This road trip from Seattle, WA to Depoe Bay, OR spans roughly 300 miles and takes 6–7 hours of pure driving, but you'll want at least two days to soak it all in.

The route takes you from the bustling Puget Sound metropolis down through Washington's Olympic Peninsula, across the Columbia River, and along Oregon's dramatic coastline. You'll traverse everything from rainforests to rocky shores, with Depoe Bay's tiny harbor and whale-watching fame awaiting at the end.

• Weather hazards: coastal fog, rain (especially November–March)
• Emergency services: limited, carry a roadside kit
