People have reported being touched by something in their sleep. In a separate incident a young girl saw a man standing in the corner of her hotel room near the window, wearing a top hat as well as a suit and tie. Also, the chambers and passageways of Crystal Cave were once used as a camp for Native Americans and Civilian Conservation Corps workers in the 1940s. Some say their spirits still linger beneath the surface the park. You can go on a tour to explore the rooms and meet the ghosts.
