Palouse Falls; Palouse Falls State Park, Washington
Where to fly: Spokane International Airport
Calling all Ice Age floods fans (or any other fan of natural beauty): Palouse Falls is one of the last active waterfalls on the Ice Age floods path—and also one of the most beautiful places in the Pacific Northwest. The park offers three separate ways to experience the falls: either from the lower part of the falls, easily accessible through by the main day-use area adjacent to the parking lot; or the second, at the end of a paved path, for a more secluded canyon view; or you can head to the Fryxell Overlook for panoramic views of the falls and Palouse River Canyon.
Pro tip: For a taste of some of the best cheese in the country, head to Cameo Heights Mansion in Dayton, Washington.
