Large Banks Lake park with 280 developed and primitive vehicle campsites, including 166 full-hookup and 18 partial-hookup sites, plus showers and a trailer dump.
Steamboat Rock State Park is a large year-round recreation park at the north end of Banks Lake. The official brochure lists 26 standard, 166 full-hookup, 18 partial-hookup, and 70 primitive campsites at Jones Bay and Osborn Bay, for 280 vehicle campsites, plus five separate equestrian sites. Washington State Parks lists showers, a trailer dump, and limited availability for equipment up to 50 feet. Primitive areas have fewer services and require separate suitability checks.
The park surrounds the basalt Steamboat Rock formation at the north end of Banks Lake. Trails reach the rock plateau and Northrup Canyon, while Grand Coulee Dam is a separate nearby destination with its own seasonal programs.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
Choose among developed full-hookup, partial-hookup, standard, and primitive areas. Sage, Dune, Cove, and Bay have different winter schedules; Jones Bay and Osborn Bay are primitive and less suitable for some rigs.
