In 2009, I spent two weeks gallivanting around Australia where, among myriad attractions, the Great Barrier Reef fully seduced me. Off the coast of Queensland, the 1,400-mile-long ecosystem comprising 2,900 pristine, individual reefs is known to be the world’s largest coral reef system, an actual living, natural thing that can be seen entirely from outer space. Visitors to the Great Barrier Reef don’t hesitate exploring the waters, whether in glass-bottom and submersible boats or kayaks and scuba diving. At one point during my visit, I was asked if I wanted to hop on a helicopter to see the reef from above. I declined, believing the most practical way to see the destination was to actually immerse myself in it completely. After all, the whole point was being in the actual reef, right?
