Kayaking on the back Lagoon is just wonderful. Lots of Birds and mangrove areas back there. I believe that the dock at Rubies Hotel is the outfit that does the Lagoon Kayaking. I have seen people kayak out toward the reef, but I'm not sure if I've seen anyone snorkel from them there. I would say that I've seen lots of power boats running along inside the reef, causing some good size wakes.
