Xcaret Mexico, Playa Del Carmen, Mexico

Of the three theme parks that start with the letter "X" in the Riviera Maya, Xcaret is the most cultural. Authentic archaeological sites share space with a recreated Mayan village, so visitors can learn what life was like for the ancient people (the colorful Mexican cemetery is quite a sight). An excellent evening stage show traces the history of Mexico through song and dance. Visitors can view jaguars and manatees; check out a butterfly pavilion; and swim and snorkel in an underground river.
