Idaho Extreme Adventures / Idaho Dunes Holding
Idaho Extreme Adventures offers a private option for guided passenger tours in its decommissioned Humvee and troop-transport vehicles. The outing follows paved and unimproved roads from the St. Anthony area toward the Civil Defense Cave landmark. Private arrangements require the specified booking configuration or add-on rather than an ordinary shared seat.
