Our best Cadw locations in Wales
Conwy Castle
Rising majestically above the River Conwy, this 700-year-old fortress is widely considered one of the most magnificent medieval strongholds in Europe. Built by King Edward I in a remarkably short period between 1283 and 1287, Conwy Castle is now a UNESCO World Heritage Site.
Visitors can climb restored spiral staircases to walk a complete circuit around the battlements, offering breathtaking views that stretch from the bustling harbour to the craggy mountains of Eryri (Snowdonia). The castle's eight massive towers and the exceptionally well-preserved suite of private royal chambers provide a unique glimpse into the domestic and military life of the Middle Ages.
How to get there: The town of Conwy is easily accessible by train, with the station located only a 5-minute walk from the castle entrance.
Kidwelly Castle
Perched on a prominent ridge above the River Gwendraeth, Kidwelly Castle is a stunning example of concentric "castle within a castle" design. Originally established as a wooden Norman ringwork in the 12th century, it was later transformed by the Chaworth family into the formidable stone monument seen today.
The castle is famous for its massive gatehouse, designed to be a "killing zone" for any would-be attackers, and its beautifully-preserved chapel tower overlooking the water. Cinema fans may recognise its iconic silhouette from the opening scenes of Monty Python and the Holy Grail.
How to get there: Kidwelly station is situated on the Swansea-Milford Haven route. The castle is located approximately one mile (about a 20-minute walk) from the station.
Caerphilly Castle
Caerphilly Castle is a true marvel of medieval engineering. It’s the largest castle in Wales and the second largest in the UK. Spanning an immense 30 acres, this fortress is famous for its massive gatehouses and iconic "leaning tower," famously tilting more than the one in Pisa.
It was one of the first castles in the world to use a sophisticated water-defensive system of lakes and moats, creating a formidable stronghold that remains awe-inspiring today. It’s a perfect spot for families to explore and discover the stories of the powerful lords who once ruled here.
How to get there: Caerphilly station is a major hub on our network. The castle is a straightforward 10-minute walk away.
Harlech Castle
Harlech Castle boasts what is arguably the most spectacular setting of all the Edwardian fortresses in North Wales. Perched high on a rocky crag overlooking the dunes of Cardigan Bay, it was designed to be nearly impregnable, with the sea once reaching the very foot of the cliffs.
Harlech is famous for its massive gatehouse and its role in the longest siege in British history. On a clear day, the battlements offer breathtaking panoramic views that stretch across the sparkling blue waters of the bay to the distant peaks.
How to get there: Take the scenic Cambrian Coastal line to Harlech station. From there, it’s a short (11 minutes approximately) but steep uphill walk to the castle gates.
Caernarfon Castle
Recognised globally as one of the greatest buildings of the Middle Ages, Caernarfon Castle was built to be a royal palace and an administrative centre for the North. Its unique polygonal towers and bands of coloured stone were inspired by the walls of Constantinople, intended to mirror the grandeur of the Roman Empire.
Another UNESCO World Heritage Site, its sheer scale and architectural drama are unmatched. It has a complex maze of wall walks and tunnels that are a delight to explore. It sits majestically on the banks of the River Seiont, where you can still watch the boats bobbing in the harbour beneath the castle's shadow.
How to get there: Travel to Bangor station and take a short connecting bus journey (such as the T2 or T3 services) directly to Caernarfon, where the castle is just a few minutes' walk from the bus station.
Chepstow Castle
Stretching out along a limestone cliff overlooking the River Wye, Chepstow Castle is one of the oldest surviving post-Roman stone castles in Britain. Construction began just a year after the Battle of Hastings in 1067, making it a vital Norman stronghold for centuries.
You can marvel at the beautifully preserved Great Tower and the oldest castle doors in Europe, over 800 years old. The castle’s long, narrow design follows the ridge of the cliff, offering dramatic views of the river below and the ancient Port Walls. They still stand as testament to the town's defensive past.
How to get there: Chepstow station is located on the line between Newport and Gloucester, with the castle entrance just a pleasant 7-minute walk away.
