This is what the tunnel and cave is all about that you mentioned earlier x
The cave itself is located in the center of a large bluff that overlooks the river. The mouth of the cave opens widely but entrance to the cavern itself must be gained through a fairly long tunnel. The cave is not large compared to most commercial caves; however its true length is unknown because of narrow passages that go beyond the 500 or so feet accessible to visitors. Although geologically, this is a dry cave that has been carved from limestone, in wet weather, a stream gushes from the mouth of the cavern and tumbles over a cliff into the river below. This makes the cave nearly impossible to navigate and even shouted conversations become inaudible over the roar of the water.
In dry times, the cave has proven to be quite an attraction to curiosity-seekers and ghost hunters. Once you pass through the entrance passage, the visitor enters a large room that opens into yet another tunnel and an overhead passageway. Another large room can be found at the rear of the explored portion of the cave, but from that point on the tunnels become smaller, narrower and much more dangerous.
The Bell Witch Cave became an attraction thanks largely to a man named Bill Eden, who owned the property for a number of years. Eden was a wealth of information about the cave and about the fact that strange occurrences were continuing to take place on the land that once belonged to John Bell. Although he was mainly a farmer, Eden did make some early improvements to the cave by adding electrical lights, but that was about all.
Despite being undeveloped though, the cave managed to attract hundreds of visitors every year who wanted to be shown through it. Bill always obliged although was always puzzled about how they found the place. There were no signs to point the way at that time but somehow people tracked down directions to the site and they always asked to hear the stories of the witch, and the stories that Eden spun from his own weird experiences at the place.
Many of the strange experiences actually happened to Bill Eden himself, while others involved visitors to the cave. For instance, a woman came to visit one day and asked to go down and see the cave. She had brought a group of friends along and in all, about fifteen people followed Eden down the rather treacherous path to the cave’s entrance. All at once, the woman in charge of the group abruptly sat down in the middle of the path. One of the people who was with her asked why she was sitting there, and she answered that she wasn’t! She claimed that a heavy weight, which felt like a ton of lead, was pressing her down to the ground and she couldn’t get up. Several members of the group managed to get the lady to her feet and half carried her back up the hill to her car.
