Spanning approximately 160 acres (65 ha), and reaching an elevation of 1,282 feet (391 m) at Crow Knowl, Crompton Moor is one of the largest open spaces run by Oldham Countryside Service.

The Friends of Crompton Moor[4] are an active conservation group, who work in partnership with Oldham Countryside Service to maintain and protect this locally unique environment.

[2] An early type of axe known as a palstave has been discovered on Crompton Moor, providing evidence of Bronze Age human activity.

[5] During the 18th century Crompton Moor had several farms; dry stone walls still exist from these times as evidence of field division for pasture.

A significant fire occurred in 1995, raging for over two weeks and burning a large proportion of the surface vegetation as well as the subsurface peat.
