There is nothing like diving at the Great Barrier Reef. There are many places in tropical North Queensland you can snorkel or scuba dive to see the Great Barrier Reef. We chose to take an overnight boat from Cairns and did two intro dives (we aren’t yet certified but now definitely want to be!) and multiple times snorkelling. We saw a manta ray, cuttlefish and nemo (clown fish). There are parts of the reef that look like they are dying but if you go on a boat further out from the shore we found it to be a better experience. Also.. the sunset is absolutely magical!!
