This was given a rating of '1' because of the most amazing snorkel trip! There was a boat ride out to Buck Island where we were treated to an underwater marine trail. The crew on the boat divided our group of 23 into 3 so that we had a guide. It was great fun to snorkel along, looking down at the trail marked with tiles telling of various sea life (even an occasional tiled arrow so we wouldn't stray), Our guide would dive down and sweep the sand off the tiles as it collected rapidly). There was one final tile 'End of Trail'! Loved it. The water was crystal clear. I also scuba so have been to the Caribbean many times; I was so impressed with this marine sanctuary. The coral reefs are being protected and it shows. There was even a turtle, surprise! No one had to feed it for it to float by us :~) Lovely, memorable experience.
