Discover The Three Castles Walk in Monmouthshire, a 19 mile circular route linking the medieval castles of Grosmont, Skenfrith & White Castle. It takes the walker through an undulating landscape of wooded hillsides and hidden valleys across north east Monmouthshire. The countryside in this area retains a strong local identity with its fine tapestry of hedgerows, copses and woods; its maze of narrow lanes, tracks, bridleways and paths; its distinctive old market towns, villages and hamlets; and its secluded historic farmhouses and churches.

This is the perfect training trail with an approachable distance but also a good amount of elevation gain to make it worth your effort. It has really good varied terrain from good flats, to steep trees, river crossings and rocky or rooted sections. It pretty straight forward if you pay attention and has an epic view of Vancouver at the top. The entire trail can be descended at a good running pace as well which is excellent. Starts and ends at the yellow gate just steps away from the parking.
