The diving excursion on the Nautilus Explorer to Islas Revillagigedos was an unforgettable adventure. The boat ride was very comfortable, considering the long journey to the dive site.Β Despite rough seas on the return trip, the boat ride was stable. I was very impressed with the crew and the way the boat was operated; everyone was courteous and attentive. The food was exemplary and water and juice were always offered before and after diving. The boat is designed for maximum safety, and is a top priority for the crew. In addition to the high quality experience on the boat, the diving was beautiful. I was exciting to see mantas rays, sharks and other marine life. As an underwater photographer, it was great to visit areas that offered a variety of subjects, including juvenile white tip sharks, cuddling up to moray eels as if they were mom.Larry
