Diamond Caverns
A privately run show cave opened in 1859, with dense, colorful stalactites and flowstone that make it the most ornate 'decorated cave' around Mammoth Cave.
Diamond Caverns is located in Park City, just outside the park's south entrance. Its dripstone decorations are far richer than those in the main Mammoth Cave passages. Stalactites, stalagmites, curtains and sparkling calcite crystals cover the walls and glitter under the lights like diamonds. The tour takes about 1 hour and covers less than 1 km on foot. There are many stairs, but the paths are level, making it suitable for visitors with limited time or children. Tickets are sold separately and are not part of the national park. It pairs well with the Frozen Niagara tour at Mammoth Cave for a comparison of two very different cave landscapes.
