I haven't found much snorkeling in St Kitts personally but if you go to Aruba, go to Boca Catalina or Baby Beach for snorkeling. We love Aruba and just came back from a 10 day stay there. Also, if you want to book DePalm Island, we found snorkeling there pretty awesome too and you could make a day of it there with a lot of other things to do (like ziplining, beach, waterpark)
