Palouse Falls State Park is a 105-acre (42 ha) Washington state park in the Palouse region of Eastern Washington, USA. It is named for the 200-foot (61 m) Palouse Falls on the Palouse River, which are part of the park. The park contains displays explaining the region's unique geology as well as its historical ties: the Palouse Indians and the Mullan Road both took advantage of the easy access to the plateau in the vicinity of the falls.
