Three Castles Walk (Monmouthshire)
Traces a challenging 19-mile circuit linking White, Skarrith and Grosmont castles through rolling Monmouthshire countryside. Expect moderate to steep climbs with significant elevation changes across farmland, woodland and quiet lanes. Not suitable for buggies or very young children due to length and terrain, but dogs welcome on leads near livestock. Rewards walkers with three medieval ruins, sweeping valley views and genuine rural solitude—best tackled over two days or as separate shorter sectio
