Watch for more information about the car cruise to Palouse Falls. Palouse Falls may be a teeny, tiny state park, but in our opinion, it is still worth heading off the beaten path. Located in Washtucna, Washington, it is in the middle of nowhere, which means it does not bring in the crowds that many other Washington State Parks do. But for many, this is part of the appeal. At just under 100 acres, it’s not packed with things to do, but the landscape is unique and there is always the stunning namesake waterfall to enjoy.
