The Narrow Neck Plateau is an eroded remnant of a sandstone layer situated at an elevation of 1,000 metres (3,300 ft) above sea level and part of the Blue Mountains, a spur line of the Great Dividing Range immediately southwest of Katoomba in New South Wales, Australia, within the Blue Mountains National Park.

The neck juts southwards from Katoomba for a distance of some 10 kilometres (6.2 mi) and ends at Clear Hill, overlooking the Wild Dog Mountains.

[citation needed] On a day of high visibility it is possible to see from Mittagong in the south to Toronto in the north and a number of peak landforms in between.

A nineteen-year-old British backpacker Jamie Neale was found alive after twelve days lost in the Blue Mountains.

[2] Upland swamps on Narrow Neck Plateau have been identified as potential habitats for the rare Blue Mountain Water Skink.
