The Great Barrier Reef is the world's largest coral reef system and it can be found off the coast of Australia. A huge underwater system of thousands upon thousands of reefs which cover 344,400 square kilometres.
It has been said that under this vast marine ecosystem lies about 10% of all marine species on our planet combined. And with an average depth of 45 metres (and at some parts reaching more than 2000 metres), the choice of activities is pretty much endless for anyone interested in exploring it.
It is the largest living thing on earth – so big in fact, that you could fit Tokyo's Shinjuku district inside it five times over. To give you some perspective of how big this actually is – if you were to scuba dive your way along the entire length of the Great Barrier Reef (which I highly recommend), it would take roughly six months to complete!
You can still see plenty of the Great Barrier Reef without having to scuba dive. You'll be able to witness first-hand the beautiful, vibrant colours and all of the wildlife on offer – it's just a matter of finding your perfect vantage point!
