Babylon is a swim but it is SO worth it! There are a myriad of shore diving sites on Grand Cayman, however, few are as spectacular as Babylon. The winds must be right for you to think about doing it..ie: no surf! The wall is so spectacular here. If you have good swimming ability and don't mind the snorkel out, take the plunge when you hit the wall and then scuba back in following one of the fingers back to shore. This makes for a great profile and takes care of your safety stop too. Enjoy!
