Why the Welsh Coast Is Made for Castle Hunting

Few places on earth pack so much fortified history into so few miles. Along the Welsh coastline you can stand on a battlement watching fishing boats bob in a harbour one minute, then be eating an ice cream beneath a 700-year-old gatehouse the next. The castles here were not built as romantic follies — they were hard-edged instruments of conquest and defence, and the landscape that made them necessary is the same landscape that makes them such a pleasure to visit today.

Much of the drama dates from the late thirteenth century, when Edward I ringed North Wales with a chain of fortresses so ambitious that parts of the group now hold World Heritage status. Add earlier Norman earthworks, native Welsh strongholds and Tudor-era additions further west, and you have a coastline that rewards a long weekend as much as a fortnight.

Conwy: The Complete Coastal Package

Conwy is the easiest place to fall in love with this stretch of coast, because the castle and the town were built together as a single statement. The fortress has eight enormous round towers and walls that still enclose the old streets almost entirely. Walk the town walls first — they run for roughly three-quarters of a mile and give you the best free view in North Wales — then pay to climb the castle towers themselves.

Practical notes: the castle sits right beside the quayside, and parking fills fast in summer, so aim to arrive before 10am or use the park-and-ride. The smallest house in Britain is a short stroll away, and the quayside is the spot for a plate of mussels or a bag of chips. Telford's elegant suspension bridge crosses the estuary just beyond the castle walls and makes a lovely ten-minute wander.

Caernarfon and the Menai Strait

Caernarfon Castle is the showpiece, and rightly so. Its polygonal towers, banded stonework and carved eagles were designed to look unmistakably imperial, and the sheer scale still surprises first-time visitors. Allow two hours minimum — the ramps and towers are extensive, and there is plenty of family-friendly interpretation inside.

The walled town is a delight to wander, with narrow lanes, independent shops and a waterfront that catches the evening light beautifully. Cross the Menai Strait to Anglesey and you reach Beaumaris, my pick for younger children. It was never finished, which means no dizzying spiral staircases to worry about, and it sits beside a wide grassy area perfect for running about and picnicking.

Pembrokeshire's Coastal Fortresses

Head south-west and the character changes. Pembroke Castle is a genuine giant, birthplace of Henry VII and built over a cave that you can actually walk into. The great round keep is one of the finest in Britain, and a full circuit of the walls takes a good hour.

Nearby highlights worth building into a day:

• Carew Castle and Tidal Mill — a tidal mill, a ruined mansion, a Celtic cross and a picnic area all on one site. Check tide times before you go, as the mill pond fills and empties dramatically.
• Manorbier — often described as the most romantic ruin in Wales, above a sandy beach and a short walk from the village pub.
• Cilgerran — a quieter, wilder ruin perched above the Teifi gorge, excellent for a walk and a look at the birdlife.

Practical Tips for a Castle Day Out

A little planning turns a good day into a great one. Most of these sites are outdoors, and coastal weather changes quickly, so layers and waterproofs are essential even in July.

• Wear sturdy shoes with grip. Grass ramparts, worn spiral stairs and cobbles are unforgiving in trainers or sandals.
• Buy a joint heritage pass if you plan to visit three or more sites — it pays for itself quickly and covers many of the castles above.
• Check seasonal opening hours online before travelling, as several places close or run shorter days from November to March.
• Ask about family tickets and activity trails at the ticket desk; most sites run free quizzes or brass-rubbing sheets for children.
• Dogs are usually welcome in the grounds but rarely inside the towers — check ahead if you are travelling with a dog.

Picnic Spots and Harbour Views

Some of the best moments on this coast cost nothing at all. The grassy banks below Conwy's walls overlook the estuary and the mountains of Snowdonia beyond. In Beaumaris, the green beside the castle is made for rugs and a cold drink. Manorbier's beach, reached by a short path from the castle, is a fine place to swim if you are brave and to build sandcastles if you are sensible.

For something more substantial, the towns attached to these castles do proper food well: bara brith and Welsh cakes from a bakery in Caernarfon, a pub lunch in Pembroke's main street, or a crab sandwich on a harbour wall almost anywhere. Finish the day with a slow walk along the water, castle silhouetted behind you, and you will understand why this coast has been fought over for centuries — and why it is so easy to keep coming back.
