Combine Mayan history at Tulum, the only archeological zone in the area overlooking the ocean and is believed to have been the largest port for the Mayans. Then the natural beauty of Xel-ha, a natural aquarium which is ideal for snorkeling.
With this tour, you'll have free food at any of Xel-Ha's five restaurants or ice cream parlor, and a full open bar. You'll also get free lockers, hammocks, life jackets, floats, river train, and snorkeling equipment. A great deal.
