Note on the data: No whale-shark or sailfish sighting entity is created because both headline visitor encounters are surface snorkelling. Exact fees and site coordinates need periodic review. Water temperature: Rounded Caribbean surface planning bands. Access: CUN requires a road transfer and ferry; local dive boats leave from the island or Cancún.
