After pickup in an air-conditioned van at your hotel in Riviera Maya, head to the Tulum ruins, which sit on 39-foot-tall (12 meter) cliffs along the coast of the Yucatan Peninsula. There, explore during a guided tour that covers the historical significance of the Maya archaeological site.
Following Tulum, hop on an ATV and drive through the Maya jungle on your way to a snorkeling site, where you swim in a cenote, a type of underwater cave that's found all around this region of Mexico. A traditional Mexican lunch with grilled meats, salad, beans and rice, and chips, along with nonalcoholic beverages, is included. At the end of the tour, get dropped off at your hotel.
