St. Anthony Sand Dunes are a striking landscape north of Rexburg, where pale quartz sand forms rolling dunes against a big Idaho sky. The area is especially known for off-highway vehicle riding, but parts of the dunes also appeal to photographers and walkers looking for open desert scenery.
Conditions matter here: summer heat, wind, seasonal closures, and vehicle rules can shape the visit. Treat it as an outdoor excursion rather than a casual roadside stop, and check Bureau of Land Management guidance before heading out.
