Why dive in a crowd? If you want to experience the best of Grand Cayman scuba diving, experience it with Neptune’s Divers! Although our boats can hold 12 divers or more, we chose to keep the groups small with no more than 8 divers per trip. Experience Cayman diving in a more relaxed and personal way. You’ll see why such a large amount of our divers are repeat customers coming back time and time again.
