Garrafón sits at the southern end of the island near Punta Sur. Once a public national underwater park, Garrafón is now operated by Dolphin Discovery.  Myriad water activities include snorkeling, kayaking, a dive platform, and swimming. Although there are some tropical fish in the snorkeling area, most of the reef has died. The pricey park also offers a swimming pool, zip line, bicycle tour, restaurant and bar, beach chairs, shaded hammocks, changing rooms with showers and lockers, and gift shop and is only worth the cost if you spend the day here and take advantage of all the facilities. Admission costs $79 ($54 for children under 12); the all-inclusive package includes buffet lunch, domestic open bar, and use of snorkeling equipment and kayaks. Swimming with dolphin packages are also available, as are VIP packages that include a private, air-conditioned gourmet restaurant and bar. Round-trip transportation between Cancún and Isla Mujeres is also available if you’re staying in Cancún.
