This is a belated review for the most memorable trip that my girlfriend and I did in November 2019. As someone who has been to Hawaii many times, I was very interested in seeing the Great Barrier Reef and we decided to do the all-day snorkeling trip and we enjoyed it so much that we did it a second day. The first day was on the catamaran to snorkel and then visit Whitehaven beach. The boat was just gorgeous and we enjoyed setting off while lounging on the front of the boat. The snorkeling itself was to a rather crowded spot with a lot of other snorkelers just offshore of another island. The sea life was very similar to Hawaii and visibility was amazing. Explore offered a nice lunch onboard and later we went to the pristine Whitehaven beach for a few hours. The best was that the Explore crew dropped us off with a big cooler of drinks to enjoy at our leisure. Second trip was just a day trip to snorkel for a longer period of time -- this one was on a larger boat and the snorkeling was much better, in deeper water, and with fewer people around. Much more enjoyable. And again, a great lunch. My only complaint is that this boat did not have a lot of outside space and I much prefer the catamaran. Some may prefer being in an enclosed area in the shade but I loved soaking in the sun. We were fortunate to have skipper Anthony both times. He was entertaining, with his Australian humor and he was very great about guiding us through our day and we enjoyed getting to know him -- a good mate! Highly recommend this tour group and the experience. It's a day you'll remember.
