The team were awesome and made sure we had all the gear and some idea of what we were doing. We got to see so much wildlife at all three spots which were all completely different from each other. A great day out, would 100% recommend

I acknowledge that this tour is expensive, but it was completely worth the investment. This was a once-in-a-lifetime adventure, and none of our family of four will ever forget it. The boat was a very comfortable spot to spend the day (when we weren’t in the water) and the food was tasty (albeit not fancy — but we didn’t sign up for the food!) The places they took us to snorkel were absolutely amazing. We went to three different spots, and each on was more amazing that the last. At two different locations, the guides gave us tours of the reef, to point out interesting featured (like a GIANT giant clam). They also had free wet suits available for everyone, which we happily used to keep warm during the slightly cooler winter season. We spent over three hours in the water, which was more than enough. (In fact, I came back a bit early on the final dive as I was getting a bit tired and chilly — but others stayed out the whole time, including the rest of my family). We saw whales and a sea turtle from the boat too, which really added to the experience. The only aspect of the tour that wasn’t quite as polished as the rest was the talk that one of our guides gave between dive sights. Her facts seemed a bit muddled, and she contradicted herself with dates and ages. That was more amusing than anything else to us, as we were there for the sights — which we got in spades. But if you are seeking an educational tour, this one may not be for you.
