A Short Walking Holiday Break

The Three Castles Walk links the Trilateral Castles, a triangle of Norman castles built by Hugh de Burgh, to maintain a grip and a line of defence along the turbulent Welsh Marches. Walking through the quiet Welsh border countryside of sheep pastures and patchwork fields, it is hard to imagine the peaceful countryside as the backdrop of fierce medieval conflicts.

You will walk old monks path, along quiet riverbanks and an energetic ascent over Graig Syfyrddin descending to the sleepy little village of Grosmont to its castle, fine church, old market hall and narrow main street, scene of dramatic encounters between Henry III and Llewellyn’s fierce Welshmen in 1233.

From Grosmont, you follow the trail through the Monnow valley to the tiny hamlet of Skenfrith on the meandering river Monnow. Time appears to have stood still, as you find yourself amongst the picturesque rows of cottages that have sprung up around Skenfrith Castle and its gem of a C13 church and wooden belfry.

Your walk then takes you to White Castle (Castell Gwyn), which remains well preserved within the fortifications and moat encompassing. The castle looms over the peaceful, surrounding farmland, with views across to the Black Mountains, the Skirrid (called Holy Mountain) and the Brecon Beacons.

Path Walkthrough

Our Three Castles walking route links the famous castles of the Monmouthshire area

Walkers can expect a landscape very typical of rural Wales, with farmland, fields and wooded hills, and the going underfoot fairly wild outside of the country lanes and winding market town streets. The path is generally easy, but there are some undulating sections, as well as untamed parts of the path - which can make progress harder. The areas quiet nature, with farm and storehouses being the most developed use of the land, may account for some of the more unruly and less beaten parts of the path.

The part of South Wales is renowned for its scenic walks, and traveling from White Castle to Grosmont over Graig Syfyrddin (aka Edmund's Tump), you'll find picturesque views over the Marches and the Black Mountains of South Wales. From Grosmont, you'll be able to stop at the pretty village surrounding the castle before heading over to Skenfrith, on the banks of the river Monnow.

  • Best Time to Travel

    Weather conditions in Wales are not too dissimilar from the rest of UK, albeit when travelling through Wales we advise carrying a waterproof jacket as you can never rule out the possibility of showers.

    Please note that some sections can be particularly muddy after prolonged wet spells across the area.

    That being said, in the summer months these wet spells are a lot less prolonged than the winter months, ideal for getting outdoors and spending the day walking through the countryside in the sunshine.
