Hartley Vale is a small village in the Blue Mountains area of New South Wales, Australia.

The area is largely open countryside with many substantial private properties, bounded by the River Lett to the north and Mount York to the south.

Parts of his original road can still be seen at Mount York, immediately south of Hartley Vale, and have been incorporated into a walking track.

[4] Hartley Vale Station was created on the Main Western Line, but closed in 1975 and no longer exists.

[6] Hartley Vale was the longest lived of the oil shale mining and refining sites in New South Wales, with operations occurring between 1865 and 1910.

In April 1906, the company and its operations at Hartley Vale and Torbane were acquired by the Commonwealth Oil Corporation.

Hartley Vale Road, where it descends into the valley, follows a part of the original Bell's Line route.
