A route devised to highlight geology, landscape and associated heritage by linking geological sites in the Abberley and Malvern Hills Geopark, it makes a sinuous north-south traverse from the Severn in Shropshire through Wyre Forest coalfield to the windblown sands of Hartlebury Common near Stourport, crossing to the Abberley Hills and then along the crests of the ancient Malvern Hills. In Gloucestershire it traverses the Leadon valley and visits May Hill and Huntley Quarry Geological Reserve before crossing the Vale of Gloucester and Severn as the Cotswold Hills come into full view.
