Once underground, you’ll encounter a treasure trove of formations: stalagmites rising from the ground, stalactites hanging from the ceiling, and flowstones draping the walls. Visitors have commented on the beauty and diversity of these features, noting that each new cavern section feels like stepping into a different world. One reviewer described the shapes as “so beautiful,” while others admired the “massive cave rooms” and “amazing formations” that have been forming over thousands of years.
