Summary
The Monnow Valley Walk is a walking route in the Welsh border counties of Monmouthshire, Herefordshire, and Powys. The walk follows the River Monnow upstream from its confluence with the River Wye in Monmouth to its source on the east side of Hay Bluff in the Black Mountains, close to Offa’s Dyke Path. The river forms a section of the Wales–England border as well as much of the boundary between Herefordshire and Monmouthshire.
Taking the course of the river upstream from Monmouth, the walk visits Rockfield, Tregate Bridge, Clppers Wood, Skenfrith, Grosmont, Monmouth Cap, Llancillo, Walterstone, Oldcastle, Clodock, Longtown, Craswall, and Hay-on-Wye. The route links with several other long-distance paths, including the Three Castles Walk, Three Rivers Ride, and Offa’s Dyke Path.
