  • This was an extremely disappointing tour. Coral World is in a remote area of St. Thomas, accessed by taxi from the cruise pier and takes about an hour to get there, especially if Coral World is not the only destination. When we arrived we were told to go to a location to board the semi sub at 2:15. There were 2 other couples waiting. It was very hot and they did not have fans on. After a very long wait--far longer than the 2:15, the tour guide showed up, bringing a larger group of people. He took us on a very treacherous path of loose stones, up and down stairs to the dock, telling us how wonderful their new construction was going to make Coral World The boat itself was old and run down as is most of Coral World and the view of undersea very cloudy. Had not a diver appeared to disperse food, no fish would have been seen. We saw a few tropical fish, some small sharks and the sea bottom corals. Nothing beautiful as the video on the boat shows in vivid color!

    For the price it was not at all worth it and I think Viator should rethink dealing with this location. I have seen way more beautiful aquariums and tropical fish elsewhere and for less money. They advertise and glory in their opportunities for human interaction with wildlife which is scientifically known to be damaging to the wildlife.
    My photos did not come out due to the murky water.

  • Water was a bit murky due to rain, but the trip itself was very enjoyable.

  • kids loved it.

  • My kids enjoyed the submarine cruise, and it was very informative.

  • Coral World, like most things on the island, is hard to find without proper street signs. The park is small, especially if you don't know to bring your bathing suit so you can buy the water experiences. The sub ride was good, but it's short and pretty crowded. Glad we did it, but we peobably won't do the sub again.

  • Loved it. Wonderful tour and guides were very informative.

  • Great fun and wonderful tour guide
