I extended one of my trips to the Caribbean to go to the Cayman Islands and snorkeled in the Coral Garden with Stingrays and also with Green turtles in a breeding pond. This was in June 2017. for information on snorkeling sites see; https://www.visitcaymanislands.com/en-us/things-to-do/watersports/snorkelling.
