Part of the long distance Wye Valley Walk.
Walkers travel from around the world to enjoy this classic long-distance route, which follows the Wye for 136 miles of river and hill walking, from the rugged upland moorlands of the mountains of mid Wales to the Severn near Chepstow. No need for a passport as you criss-cross the border between Wales and England and ramble through the rolling fields and cider orchards of Herefordshire. The Wye Valley Area of Outstanding Natural Beauty, with its dramatic limestone gorges, stunning viewpoints and romantic ruins at Tintern Abbey, provides a spectacular 50 mile finale to the walk, which ends in the shadow of a clifftop medieval castle at Chepstow.
