Columbia County was one of the earliest settlements in the history of the Pacific Northwest. Many beautiful buildings and homes from the late 1800’s and early twentieth century still stand today and serve as a reminder of Columbia County’s prosperous history. Dayton is home to three national historic districts, including the oldest train depot and oldest working courthouse in the State of Washington and over 120 buildings on the National Historic Register.

Columbia County is geographically diverse, stretching from 500’ elevation at its northern Snake River border to 6,500’ at the top of Oregon Butte to the southern Blue Mountains border. The 868.8 square miles features a productive landscape with rolling hills, bountiful crops, pristine rivers and private and national forest lands.

Building on its original foundation of agriculture, Columbia County has encouraged economic diversification in order to remain vital and healthy yet has retained its rural charm. Dayton’s Main Street underwent a major revitalization in the early 1990’s, now home to essential business services as well as unique shops, Victorian lodging and some of the best restaurants in the state.
