    We decided to do Low Isle after the outer Great Barrier Reef (we had rough weather conditions). The coral was not as vibrant in color or as diverse and the water was slightly less clear. The coral was shallower at Low isle and the water was much calmer which provided more pleasant relaxed snorkeling. We saw 3 sea turtles and were able to swim alongside them which was amazing. The fish species at low isle are also very colorful and varied. We definitely were able to snorkel longer in the calmer water. Plus you can always retreat to the island if feeling slightly unwell. Only complaint is equipment could use a little upgrading.

    Excellent half day, crew very knowledgeable and everything felt very safe. I enjoyed the snorkelling and my husband, who doesn’t swim, took great photos on the glass bottom boat and the bird life on the isle. Pouring rain didn’t spoil our experience at all and in fact it was rather nice to feel so cool! We were there in the rainy season so couldn’t complain about that. Thank you Imogen for great snorkel tour and Gus and was the third member Mark?

    We had the most amazing time, so happy we did this! The group was small and we were well looked after. The conditions were incredible, very clear, and we swam inches away from turtles! The guides told us loads about the reef and were there to help in any way needed. Best snorkeling trip we've ever been on, will defo go again :)
