Australia is awash with superb scenery but Blue Mountains National Park perhaps has the country's most dynamic offering. An area characterised by sheer cliffs, sweeping valleys, tranquil eucalyptus forests and dramatic waterfalls, this region of eastern Australia is well worth a visit. In the heart of the landscape, Hanging Rock is a huge sandstone ledge that became detached from the main cliff and now juts out over Grose Valley, 328 feet (100m) up.
