Monnow Valley Walk
The Monnow Valley Walk is a long-distance trail in Wales that stretches from Monmouth and follows the River Monnow upstream for about 37 miles through diverse landscapes. It passes through small villages, woodlands, and open fields while passing near historic castles at settlements like Skenfrith and Grosmont, ending higher in the hills toward Charwel Ddu.
The trail begins in Monmouth, a town with medieval roots and ancient structures, passing through areas marked by defensive castles at settlements like Skenfrith and Grosmont that guarded this Wales-England border zone. In places, the route runs close to Offa's Dyke, an 8th-century earthwork that once marked the border between kingdoms.
The trail reflects how communities have shaped the Monnow valley over generations, with traditional farms and centuries-old stone bridges that still serve the villages they connect. Walking it, you notice how locals use the river and land, and how rural life differs subtly on either side of the Wales-England border.
The path is walkable for most people with gentle terrain and well-marked sections on most of the route, though it becomes steeper as it approaches the Black Mountains. Bring a map or GPS file and plan to rest in small villages along the way, as some stretches have few facilities or services.
Ancre Hill Vineyard sits along the route, offering a surprising chance to taste Welsh wine and learn about winemaking in a region not known for producing it. This stop creates an unexpected contrast to the surrounding castles and countryside, introducing visitors to a craft that few would anticipate discovering on this heritage trail.
