In our area Lincoln Caverns hosts a Ghosts and Goblins tour each year. Costumed guides explain the wonders and highlights of a haunted Lincoln Caverns while supporting characters provide humor and horror along the way. The caverns are wonders of nature. This is a great fun activity for children and adults. I think that the cave it a little eerie anyway with so many bats and the unusual rock formations. During the Halloween season, it can be very frightening.
