Wentworth Falls is a town in the Blue Mountains, New South Wales located 100 kilometres west of Sydney, and about 8 kilometres east of Katoomba, Australia on the Great Western Highway, with a Wentworth Falls railway station on the Main Western line. The town is situated at an elevation of 867 metres (2,844 ft). At the 2006 census, Wentworth Falls had a population of 5,650.
Originally called The Weatherboard after the ‘Weatherboard Inn’ built in 1814, a year later the town was named Jamison’s Valley by Governor Lachlan Macquarie in honour of the colony's leading private citizen, Sir John Jamison. In July 1867, the first railway journey to the Blue Mountains left Penrith and traveled through to Weatherboard Station, where the train terminated. In 1879, the village took its name from a nearby system of waterfalls, which in turn were named for William Charles Wentworth, one of the men that headed the exploration to cross the mountains in 1813 and a friend of John Jamison.
