The tallest single-structured sand dune in North America rises to 470 feet high 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, bird watching, 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 on the dunes. A visitor center offers information on birds of prey, insects, fossils, wildlife and sand dunes and gift items for purchase.
