The hardest part of this dive for us was the entry and the exit. We entered and exited on the rocky beach west of the Sheraton which would have been fine without any surf, however some surf was present and our hands got scraped up a little bit. I would recommend entering and exiting from the sandy beach in front of the Sheraton even though the swim is a little longer. We are in good shape, and so the 1/4 mile swim out and 1/4 mile swim back were relaxing. The dive is absolutely fantastic. Besides being named Sheraton Caverns, it should be named turtle city. I have never seen so many turtles. Turtles flying every which way, turtles eating, turtles fighting, turtles sleeping in rooms in caves. The most fascinating part was meeting and passing turtles as they would fly through the arches and lava tubes. Knowing this dive's location was only possible for us when a dive boat anchored there. Thanks to the dive boat operators and their customers for showing the location of this fantastic dive to us shore divers.
