Steamboat Rock State Park - Washington

US National Parks and Monuments Travel Guide:

Park Overview

Steamboat Rock State Park is a 3,522-acre camping park with 50,000 feet of freshwater shoreline at the north end of Banks Lake. Dominating the landscape is a columnar, basaltic rock with a surface area of 600 acres. Two campground areas and a large day-use area are on sweeping green lawns, protected from winds by tall dramatic poplars. The surrounding areas are carpeted with wildflowers, adding to the gray-green brush of the Scablands. A sandy swimming area and boat launches make the area a favorite for visitors who enjoy water-play and want respite from the hot, summer sun.


Steamboat Rock is a long-established area landmark, first used by nomadic Native American tribes and then by early settlers. The military currently uses the area for aircraft flying training missions. The basalt butte rises 800 feet above Banks Lake. It was once an island in the Columbia River bed. When the Columbia returned to its natural course, after centuries of being dammed by ice, the massive rock remained.

There is also a well-engineered road, built in the late 1800s, that winds through and up the south side of Northrop canyon. Once used by stage coaches and freight wagons, it was named after one of the original homesteaders.
