We took the 9-12 snorkeling trip. The crew was very professional and informative. The location was in pretty deep water near a reef. Unfortunately, the current was pretty strong that day and it was hard to get to the reef and stay there because we were constantly being swept back toward the boat. In those conditions, I would not recommend this activity for the elderly or unfit persons. Our older relatives did enjoy the boat trip but did not partake of the snorkeling. If you are not a very strong swimmer be very sure to take the offered pool noodle.
