I have mostly visited AC during high season and often see people snorkeling (tourists) off the docks by Ramons or Casa Verde and they go way far out from the docks - and I have often thought about how dangerous that is and I tried yelling at a couple once and I think they thought I was crazy. Maybe because its low season and there are not as many boats out - or maybe they did not realize how far from the beach/dock they were - its a terrible and tragic story.
