The tour (relatively inexpensive) is about 50 minutes long down 220 some feet into the earth. Beautiful columns and caverns. Knowledgeable tour-guides. Highly recommend for families with elementary age school kids. There's a wildlife park on the complex which we didn't visit but the resort staff said it's pretty neat - you drive thru and the animals supposedly come right up to the car (depending on the heat).
