Steamboat Rock State Park

Steamboat Rock State Park is a nature reserve near Banks Lake featuring a distinctive columnar basalt rock formation and extensive waterfront access. The site provides campsites, hiking trails, and multiple boat launch areas for water recreation.

The region was home to Native American peoples for thousands of years before the construction of Banks Lake reshaped the landscape as part of the Columbia Basin Project. These changes created the geological foundation and water features that define the park today.

The columnar basalt formations have long drawn people to study and experience the landscape shaped by ancient geological forces. Visitors can observe how the rock formations influence where people gather and what activities the place supports.

The park is most accessible in spring and fall when temperatures are mild and the area feels less crowded. Visitors should know that snow in winter can limit access to some areas.

The tall basalt cliff is shaped like a steamboat paddle wheel, which is how the park got its name. This makes it a visually distinctive landmark in the otherwise flat region.
