5,043-acre Banks Lake park with 144 full-hookup RV sites in poplar-shaded loops, named for an iconic 800-foot basalt formation rising from the water.
Steamboat Rock State Park is one of Washington's largest and most dramatic parks, built around a 800-foot columnar basalt formation jutting dramatically from Banks Lake in the Grand Coulee. One hundred forty-four full-hookup RV sites in three loops (Sage, Dune, and Bay) are sheltered by rows of protective poplar trees planted to buffer the area's legendary wind. Facilities include ADA-accessible restrooms with showers, a dump station, boat launch, basketball courts, and a seasonal marina store. The trail to the summit plateau of Steamboat Rock rewards with 360-degree views.
Steamboat Rock State Park is anchored by the 700-foot mesa of Steamboat Rock, a remnant of the Columbia Plateau that survived the Ice Age Missoula Floods intact while the surrounding terrain was scoured into the dramatic basalt coulee of Banks Lake. Banks Lake is a 27-mile-long irrigation reservoir in the Grand Coulee — one of the world's greatest natural canyons, carved not by a river but by catastrophic floods that occurred repeatedly over 15,000 years during the last ice age. The surrounding landscape is part of the Channeled Scablands, a UNESCO-recognized geological heritage landscape found only in eastern Washington, where the Ice Age flood evidence is so dramatic it was initially rejected by mainstream geologists for decades.

Waterfront hookup sites overlooking Banks Lake are among the most coveted in all of eastern WA — book these the day the 6-month window opens. Sites near the boat launch fill next. Upper loop sites (70+) are away from the water but more private. The Steamboat Rock summit hike departs from the campground and offers 360° views of the Grand Coulee. Morning boat fishing for walleye on the lake is exceptional.
