Washington County Maps

There are 39 counties in the Evergreen State, all placed in a diverse landscape. You’ve got rainforests on the Olympic Peninsula, volcanoes like Mount Rainier, dry scrublands in the east, and the Puget Sound cutting into the western part. This mix means each county has its own unique look and feel.

Washington Counties

King County is the most populous county. It’s home to Seattle, the state’s largest city and a major tech hub. People flock there for jobs at places like Amazon and Microsoft. Meanwhile, there’s Garfield County. It’s in the southeast, mostly wheat fields and rolling hills. In the last census count, it had fewer than 2,500 people.

Okanogan County is the biggest, covering over 5,300 square miles. This county stretches from the Cascade Mountains to the Canadian border. It’s a mix of forests, farmland, and some pretty rugged terrain.

The smallest county is San Juan County, which is basically just a bunch of islands in Puget Sound. It’s only about 174 square miles, but it’s packed with scenic views and whale-watching spots.

The oldest county, Lewis County, was set up back in 1845 when Washington was still just a territory. The state’s counties also have some quirks. Pierce County got its name from the 14th U.S. President. Finally, Pend Oreille County is named after a Native American tribe but everyone pronounces it wrong.
