Last Known StatusOpen

Eastern Idaho is home to this 10,600 acre playground of white quartz dunes ranging from 10 feet to 300 feet high. The firm rolling dunes to the east are smaller and better for beginners, while the dunes in the western portion are huge and as steep as they come. The three main campgrounds along the southeastern perimeter offer many full hookup sites, but are sometimes a bit cramped.

RV travelers should make reservations well in advance for hookup sites, but there are some dry camp areas as well with chem toilets and no shade. Nearby tourist attractions Yellowstone Park and Grand Teton National Park sit a mere 100 miles to the east.
