Children usually love the self-guided walk through the main cavern's Big Room, with its many bizarre and beautiful shapes, especially when they're encouraged to let their imaginations run wild. Younger children are often bored on the King's Palace Guided Tour because it has several stops and everyone must remain with the group. (Children under 4 are not permitted on the King's Palace tour.) Families with children at least 6 years old (and preferably a bit older) enjoy the Slaughter Canyon Cave tour, which has some spectacular formations and gives the feeling of exploring a wild cave.
