Bruneau Dunes State Park
Mountain Home, ID
Home to the tallest single-structured sand dune in North America, about 140 m high, beside small lakes. The park has a campground and a public observatory that opens on weekend evenings in the warmer months.
Bruneau Dunes State Park lies in southwestern Idaho, about 25 km (15 miles) south of Mountain Home. It is home to what is described as the tallest single-structured sand dune in North America, around 470 feet (140 m) high, with small lakes nearby.
The dunes sit near the center of a natural basin that has trapped sand for more than 12,000 years. Because the winds blow alternately from the southeast and the northwest, the dunes barely migrate. Motorized vehicles are banned on the dunes, while climbing and sliding are allowed; sandboarding is also among the activities. Horse trails of 7 and 9 miles (11 and 14 km) circle the dunes.
For road-trippers: camping is available in the park. The Bruneau Dunes Observatory offers stargazing, usually on Friday and Saturday evenings from mid-March to mid-October; the current schedule is posted by Idaho Parks & Recreation (as of October 2026, check in advance).
