There are outstanding views and interesting history on this 12.5 mile circular walk, which links the Wye Valley Greenway path from Sedbury to Tintern with the Wye Valley walk between Tintern and Chepstow. Features along the way include Chepstow Castle, the old Chepstow town bridge and the 1km long Tidenham Tunnel, Tintern Abbey, an iron age, hill fort site, the Eagles nest viewpoint and 365 steps. Nearing Chepstow the route follows in the footsteps of 18th-century Wye tourists through the Piercefield estate, passing the Giants cave and a grotto created in the 1750s by Valentine Morris.
