Miller Cave is part of a cave complex in the bluffs above the Big Piney River, along the southern boundary of Ft. Leonard Wood. One of the largest caves on Fort Leonard Wood, it is the only one open to the public. A trail leads to the main entrance, in a bluff approximately 150 feet above the Big Piney River; two more openings face the river, affording a spectacular view of the river valley. Trail is steep, but a short walk.
