From early April through early November, a few cruise lines offer excursions focused specifically on the Pacific Northwest, usually along the Columbia River, leaving from Portland. Un-Cruise Adventures (formerly America Safari Cruises) offers seven-day excursions (some of them wine themed) along the Columbia and Snake Rivers, calling at Richland, Clarkston–Hells Canyon, Walla Walla, The Dalles, Hood River, Bonneville Dam, Portland, and Astoria.
American Cruise Lines runs seven-day excursions along the Columbia and Snake Rivers, departing either from Portland or Clarkston (WA), on a Victorian-style stern-wheeler, the Queen of the West.
