Before Hurricane Wilma, Chankanaab was one of the best places for off-shore snorkeling and diving, as groves of purple sea fans, large coral heads and schools of tropical fish were within a yards of land. The snorkeling’s not what it used to be, although the sea fans and other formations are slowly regenerating, and the number of fish is increasing. Because of the strong current, it’s best to go snorkeling with a guide. A better reason to visit the park is to mingle with the dolphins. Dolphin Discovery offers three dolphin encounter programs, ranging from kiss and hand shake encounters to Dolphin Swims that add belly rides to the Royal Swim, which includes a foot push – as you float face down, dolphins propel you through the water by pushing you along by the soles of your feet. Reserve ahead. Also, to avoid crowds, try to visit when the cruise ships are not in port.
