One of the most fascinating and unique geological attraction in the United States. During a one hour guided tour visitors will witness a waterfall, nearly 60 feet of high stalactites both delicate and massive, calcite flowstone, fossils that have been dated to over 400 million years old and a wedding chapel in which over 400 weddings have performed. The cave is a constant 48 degrees year round, so a light jacket or sweatshirt is suggested. Walking shoes are also recommended.
