We snorkeled in Kealakekua Bay in 2002 from a Royal Caribbean cruise. It's probably the same one. At any rate, we loved it. The bay is very popular scuba divers as well as the underwater life is unsurpassed. We' re planning on going back in 2006 and I will scuba this time. It's a gorgeous setting with calm water and lots of underwater life. Don't miss this one if you like snorkeling.
