Tree-shaded Pasco, a college town and the Franklin County seat, is an oasis of green on the Columbia River near a site where the Lewis and Clark expedition made camp in 1805. The city began as a railroad switchyard and now has a busy container port. The neoclassical Franklin County Courthouse (1907) is worth a visit for its fine marble interior.
The Pasco Basin has first-rate vineyards and wineries and some of the state's most fertile land. You can purchase the regional bounty at the farmers' market, held downtown every Wednesday and Saturday morning during the growing season.
