Such a great experience. You go over some wrecks, and then one of the crew feeds the fish outside the windows. Then you get to go up on deck, get your snorkeling gear and jump in. The water was teeming with fish, and the crew gave us a good amount of time in the water. Brilliant!

This was part of a land sea tour. We enjoyed the sea tour. This tour was very touristy, but was still fun. Found the time went very quickly. The tour guide was entertaining. Sat on benches made for two, but was still uncomfortable. We wished it had lasted a little more.

I live in Grand Cayman and had visitors this past week. They were interested in going in the Nautilus undersea tour. I filled out an online reservation form and called two different phone numbers. No one ever got back to me. My guests have left island feeling very disappointed that they did not get to do the tour.

We went early and there was no line. The guide was very informative and called out interesting sites and fish as they presented. the ride was smooth and the view was good. The benches were not overly comfortable but then again my family and I moved about little bit to get better pictures.

Our one-hour tour featured reefs with many interesting varieties of coral. We saw a young stingray glide by. Two ship wrecks with timber, metal and debris had fish swimming throughout and sea life growing all over. When our diver fed the nearby fish we were surrounded with schools of tropical fish in bright colors. I know of no other way... More

Nice tour for those who do not want to dive or snorkel, but would still like to see the reef and the shipwrecks. Comfortable and air conditioned.

We had a great time going on this tour. The main reason was we wanted to take the kids snorkeling as well. They loved seeing underwater and then go swimming. It was their first time snorkeling and they did great. The staff were helpful to find them their equipment for their size.

We have toured the waters of Grand Cayman before on the Nautilus. This was a return trip for my wife and I - this time with our kids (two in college and one in high school). It is a very educational experience - and our kids were captivated by what they were seeing underwater for the entire duration (not always... More
