Houseboat rentals in Washington
Washington's flagship houseboat destination is Lake Roosevelt, the 150-mile Columbia River reservoir behind Grand Coulee Dam in the northeastern part of the state. Managed as Lake Roosevelt National Recreation Area by the National Park Service, the lake threads through basalt canyons, ponderosa pine ridges, and open sagebrush country of the Columbia Plateau. Two full-service concessioner marinas — Seven Bays and Keller Ferry — rent houseboats. Spokane is the natural gateway for most guests, with a major airport 90 minutes to two hours from the primary rental docks. The lake is far enough from major cities that it stays quiet outside peak summer weekends and preserves a genuine wilderness feel.
Each destination below has a verified rental relationship as of 2026-07-16. Rental availability, pricing, and marina operations still change — confirm current details with the operator.
Washington requires a Washington State Boater Education Card for operators of motorized vessels 15 HP or greater — confirm current rules with the Washington State Parks and Recreation Commission. Marinas provide their own hands-on orientation before every rental.
The primary rental season is late May through September. July and early September often provide the year's best weather.
