The second day in Cairns we went out on a large boat and went snorkeling at the Great Barrier Reef. I can swim but I really hate being in water when I can’t touch the bottom, so I was very nervous. I used a couple floatation devices but eventually got really into snorkeling and enjoyed seeing all the creatures living on the reef. I was extremely excited to have a sea turtle swim near me and I watched it for awhile. I also went on a semi-submarine tour, which was a boat with a bottom that goes down and has windows lining the walls so you can look out underwater. This was a great experience and I loved seeing how beautiful the Great Barrier Reef was.
