Benton County, Washington

Benton County is right in the south-central part of Washington. The Tri-Cities area includes Kennewick, Pasco, and Richland. These places form the heart of the county.
Here, high-tech meets agriculture. Vineyards and orchards stretch across the landscape. The Hanford Site, once crucial for nuclear production, now focuses on environmental cleanup.
Locals flock to the Columbia River for water sports and fishing. This river forms a large chunk of its border. The county’s history runs deep, from Native American settlements to Lewis and Clark’s expedition. Today, it’s a blend of rural charm and urban amenities.
