Located in Owyhee County, Bruneau Dunes State Park is famed for its tall active sand dunes, which rise up to 470 feet (143 meters) — the tallest in North America outside of and beyond Death Valley. Visitors come to climb, sled, and photograph the shifting sands; nearby facilities include a small reservoir lake for fishing and paddleboarding, a planetarium and observatory that hosts regular programs, and a campground with basic RV hookups and tent sites. The park lies along State Highway 51, roughly an hour southwest of Boise; beyond the dunes are open sagebrush plains, burrowing prairie dogs, and seasonal wildflowers. Active geology, rural Idaho scenery, and amateur astronomy are central to the visit — check local sources for seasonal events and access details.
