We took the Rainbow Reef Snorkel, and it was better than expected. Obviously, the coral isn't vibrantly colored, but there was plenty of it to look at. They allowed you to go pretty far, but it was always safe. Life jackets were optional, but most people took them. The masks and gear worked very well and rarely fogged up or malfunctioned. The crew was friendly, but we were at the back of the boat and could rarely hear what they were saying. The crew also chummed the water so there were lots of fish. We were pleased with this, however, we enjoyed diving down to the rock formations the most. They were only 6ft-10ft below us, and it was fun to see the fish close up.
