Sun Lakes-Dry Falls

Sun Lakes-Dry Falls State Park is a 4,027-acre camping park with 73,640 feet of freshwater shoreline at the foot of Dry Falls. Dry Falls is one of the great geological wonders of North America. Carved by Ice Age floods that long ago disappeared, the former waterfall is now a stark cliff, 400 feet high and 3.5 miles wide. In its heyday, the waterfall was four times the size of Niagara Falls. Today, it overlooks a desert oasis filled with lakes and abundant wildlife.

Interpretive Opportunities

The visitor center at Dry Falls tells the story of this amazing geological phenomenon. From lava flows to the Ice Age floods, and from the Native American legacy to the modern discovery of how Dry Falls was created, the Dry Falls story is revealed to tens of thousands of visitors each year. A gift shop in the visitor center has a wide selection of books, maps, guides, videos, postcards, film, and other merchandise about Dry Falls and the surrounding area. At the end of your visit you will want to spend time looking through the wall of windows over the precipice, as it is magnificent. Please note that a donation helps support the operation of the center.

Throughout the park, roads and trails will take you to other fantastic views of geologic features and bring you closer to the desert plants and animals. Take time to make your own discoveries and create your own explanations for what you see. If you had been J Harlen Bretz, would you have come up with such an "outlandish" theory as huge Ice Age floods? The Grand Coulee, of which Dry Falls is a central feature, has been designated as a National Natural Landmark by the National Park Service. As you drive or hike through the Grand Coulee, please do your part to help preserve this national treasure. Admission is by donation.
