The tallest sand dune rises 470 feet above small lakes in the high desert south of Mountain Home. The state park includes desert, dune, prairie, lake and marsh habitat with opportunities to observe nocturnal species. Activities include fishing, birdwatching, camping, hiking, swimming and viewing the stars at one of only two public observatories in Idaho. Feel free to climb but no vehicles are allowed off-road or on the dunes. A visitor center offers information on birds of prey, insects, fossils, wildlife and the sand dunes. A variety of gift items are available for purchase, and we also rent sand boards. Two cabins are available for rent, and there are 82 serviced campsites with W/E and 31 standard sites. The Equestrian Area provides facilities for visitors to camp with their horses and there is a 9-mile riding trail around the park.
