The main focus for rock climbing in New South Wales is the Blue Mountains, where hundreds of kilometers of escarpments offer almost unlimited potential. Overuse led to the closure of the famous Three Sisters formation, but dozens of other cliffs, particularly those around Mount Victoria and Blackheath, provide some of the toughest ascents in the country. Perhaps the most challenging climbs in New South Wales, however, are those on 1000-foot limestone cliffs of Bungonia Gorge near Goulburn, south-west of Sydney. Ascents equally long and arduous, if not as difficult from a technical point of view, can also be made on the volcanic plugs in Warrumbungle National Park and in Mount Kaputar National Park near Narrabri. Areas suitable for winter climbing include the cliffs at Thomsons Point near Nowra, and Point Perpendicular, which rises, as the name suggests, sheer from the waters of Jervis Bay. The sea cliffs of Sydney are also popular, although their rock is friable. A less strenuous form of climbing can be enjoyed on the vast granite slabs of Booroomba Rocks, 12.5 miles south of Canberra in the Australian Capital Territory. Although they lie back from the vertical, the slabs offer a challenge because the holds are so tiny. Other granite climbing areas can be found in the New England area in the state’s north.
