Clark County, Washington

Clark County sits just across the Columbia River from Portland, Oregon, making it one of the most populated counties in Washington State. Vancouver, the county’s largest city, is often confused with its Canadian namesake, but this Pacific Northwest city has a distinct character and plenty of its own charm.

The county has a rich history shaped by Native American communities and the arrival of the Hudson’s Bay Company. Today, visitors enjoy hiking in the Cascade Mountains, along with boating, fishing, and other water activities on the Columbia River. The combination of rivers, mountains, and accessible outdoor recreation makes Clark County popular with both residents and visitors.

Technology and business growth have also become important parts of the local economy, with several major companies establishing a presence in the area. At the same time, urban and rural living exist side by side, with farmland sometimes only a short drive from busy downtown districts. That mix of city amenities, agriculture, and outdoor recreation gives Clark County a character that continues to surprise.
