To answer you question, you will need to walk into the water from the beach and get in a small boat to be noticed out to the catamaran which is in deeper water. I don't know how you get into the catamaran because we got stood up! We arrived at the beach location at 12:30 as instructed. There was no Dolphin and we were told that our reservation didn't go well. We were assured that they were substituting us into a comparable catamaran. Nothing could be further from the truth! We got on a catamaran that was about 1 trip away from the salvage yard! It was awful! They did end up refunding our money but it was a disappointment. On the up side, we saw the Dolphin at the snorkeling site and she is beautiful! Hope that helps!
