What? A road-trip to conquer a World Heritage Site — in north Wales

Where? Conwy, Gwynedd and Anglesey

Cadw sites to see: Castell Conwy, Castell Harlech, Castell Caernarfon and Beaumaris Castle

Most ‘Instagrammable’ spot: with four world-class castles in the mix, there are hundreds of picture-perfect locations to take advantage of on this itinerary. For starters, discover the hidden stairwells at Castell Caernarfon or take a seat on the drawbridge of Beaumaris Castle — both great options to accompany a thought-provoking caption.

Take a road-trip back in time to discover Castell Conwy and Town Walls, Castell Caernarfon and Town Walls, Beaumaris Castle and Castell Harlech.

Together, these four medieval masterpieces collectively form a UNESCO World Heritage Site — making them internationally recognisable, beautifully preserved and in no doubt worthy of an extended adventure.

Begin your journey in the Welsh market town of Mold and let the North Wales Way be your guide as it takes you on an epic 4-day driving route along the northern coastline into Anglesey.

Passing through the traditional seaside resorts of Colwyn Bay and Llandudno, the scenic route offers you the chance to experience an array of Welsh adventures — from experiencing the freedom of flight on the world’s fastest zipline at Zip World Velocity to watching the sun set over Llandudno Bay from the comfort of seafront restaurant Dylan’s, which is famed for its award-winning barbeque sauce.

Cross the Menai Strait on its 18th-century suspension bridge and you’re in castle territory, where you can seamlessly tick off three out of four world-famous monuments and their charming local towns: Conwy, Caernarfon and Beaumaris.

The historic walled town of Conwy is a haven for medieval adventures, with Castell Conwy, the renowned town walls and Tudor townhouse Plas Mawr situated right in the centre. And you can maximise your heritage-laden visit with a night at the unique Gwynfryn B&B, which is situated within a converted Welsh Methodist Chapel.

Meanwhile, Caernarfon is home to a stunning harbour which visitors can explore before taking in the medieval might of the town’s castle. Then, pay a visit to Segontium Roman Fort which — situated slightly further afield, on the outskirts of Caernarfon — was once used by Roman auxiliary troops as a base to defend the coastline from pirates and raiders from Ireland.

Situated on Anglesey, Beaumaris Castle is the most technically perfect (yet unfinished) medieval fortress in Britain and is a thriving hub of local wildlife. Pair your visit with a Seacoast Safaris cruise to Puffin Island — a bird sanctuary and nesting site for breeding seabirds. The island was once home to sixth century saint, St Seiriol, whose monastery is still visible.

To mark the end of your World Heritage Site road trip, join Wales’s Coastal Way to reach your final destination of Castell Harlech, before heading home with enough memories to last a lifetime. See the Sky High Itinerary or more ideas on things to do and see in Harlech.
