Just two hours north of Seattle, this colourful little city has a population of around 10,000, and a whole lot of history. Standout attractions include Fort Worden Historical State Park, which protects an old US artillery base dating back to 1898, and the Northwest Maritime Center, which offers a deep dive into working life on the water. It's a lovely place to wander too, taking in views of the Victorian-era buildings and looking across the impossibly blue Port Townsend Bay.
