The Palouse Falls lie on the Palouse River, about 4 mi upstream of the confluence with the Snake River in southeast Washington, United States. The falls are 198 ft in height.

The iconic Palouse Falls that has been deemed the official waterfall of Washington State is not to be missed. At the end of the last ice age, repeated glacial floods, known as the Missoula Floods, swept across eastern Washington carving out the unique scablands landscape we see today. Among the coulees, potholes, buttes, and plateaus, Palouse Falls remains as one of the magnificent and lasting remnants of these glacial floods. It is the only major waterfall left along this thousands of years old glacial flood path, and as of February 12, 2014, is Washington's official state waterfall. Standing at a height of 198 feet and surrounded by striking basalt cliffs, the powerful waterfall lies on the Palouse River upstream of the confluence with the Snake River.

Formerly known as Aput Aput, meaning “Falling Water,” so named by the Palouse Indians, Palouse Falls is located within Palouse Falls State Park. The park boasts a 105-acre camping area with 11 tent spaces, including one campsite that is ADA compliant. All sites are available on a first come, first served basis. You will also find other amenities including sheltered and unsheltered picnic tables, information kiosks, pit toilet restrooms, and wheelchair accessible paths. All visitors should be aware that this area is home to rattlesnakes, so be careful where you walk. You may also encounter the infamous yellow-bellied marmot during your visit. Many reside in the park and can be found grazing throughout the area.
