Author Neil Humphreys had no idea what to expect when he visited Australia's Blue Mountains for the first time... and the view took his breath away. He stayed at Katoomba Falls, marvelled at the waterfalls and canyons and then hiked along the clifftops to Three Sisters and pretended to be Rocky Balboa from Rocky IV. He enjoyed starry nights and crossed a stream - where his wife swore at him - to visit an aboriginal cave.  Through it all, he marvelled at our planet's natural wonders, emphasising why we must visit, touch and share such places, so we learn why we must cherish and protect them.
