We took our only ship excursion here. It was the Rainbow Reef snorkel. There was quite a long walk to get to the boat for the trip. They really should have transportation. There were 50-60 passengers and 3 crew members. That's not a good ratio for a beginner. We received virtually no assistance. My husband nearly drowned. Rainbow reef is dead from a rise in water temperature so everything was gray and we only saw three or four varieties of fish. Having said that, it only cost $22.00. We enjoyed the narrated tour of the waterway and enjoyed a spectacular sunset on the trip back to the ship. The tour took all of our time in Nassau. It was only supposed to be 2 1/2 hours. We wished we would have had some time to tour Nassau.
