Exploring the Formations

Every turn reveals something different. As one reviewer put it, “The shapes of stalagmites and columns formed in the cavern were so beautiful. Each new area was different.” The formations are thousands of years in the making and continue to grow. Some areas look like ancient sculptures, while others resemble chandeliers hanging from the ceiling.
