The section of the earthwork that runs from the north of Kington to the sea at Prestatyn is considered by many scholars to be the true remains of the dyke built by King Offa. The sections of earthwork to the south of this in Herefordshire and to the coast near Brockweir are sometimes referred to as "Greater Offa's Dyke".
Just to the north of Kington in north-west Herefordshire the dyke can be seen quite clearly on Rushock Hill, which has good views of the Herefordshire plain to the River Wye. The dyke begins as quite a large bank with faint evidence of the ditch to the west. From Rushock Hill the dyke heads north before curving round to the west of Herrock Hill in Lower Harpton parish, then crossing the Hindwell Brook just below its confluence with other small brooks. From here the dyke continues out of the county.
