Snorkeling at Sandals Royal Caribbean
The Royal Caribbean Private Island
You have a couple of easy options if you want to go snorkeling. The first of course is the private island off the resort. This is a great place to see lionfish, lobsters, stingrays, and scores of other small fish. While not as sophisticated as an off site snorkeling location, this is close to the resort, the pool, the swim up bar, so you can come and go as you please
Dive Center Trips
The dive center can transport you to spots away from the resort. In these places the number of aquatic species you can see greatly increases. There is no guarantee you will get the National Geographic underwater experience, but you will some sea life.
