Dove it last Sunday. One of the best dives I've been on. The light is incredible, the clarity is incredible. Beautiful fan corals, a giant clam, and myriads of sea life set against amazing limestone structures. Did I mention that light? The incredible aqua-blue light that enters through the openings in this large underwater cavern is incredible. The 100 steps back to the top will blow untrained calves for a day, but it is well worth it. Take the return slow. Loved it!
