My wife and I did an 11 day dive Safari around Bali early Dec 2012. From the start the communication with Werner was excellent, replies were prompt and answers to my questions very comprehensive. The whole trip ran like clockwork, the 14 dives we did were excellent and perfect for our level of experience. If you book through Nautilus make sure you dive Manta point at Nusa Penida, the Manta's we saw there were amazing and something we'll never forget. Our guide Gusti was fantastic and took really good care of us. He really went out of his way to find interesting marine life we would have otherwise missed. Highly recommend Nautilus if you are planning a dive trip to Bali.
