North Wales is one of the best places in the UK to explore historic castles. With dramatic mountain backdrops, rugged coastlines and centuries of history, the region is home to some of the most impressive medieval fortresses in Europe. Many of these castles were built by Edward I during the 13th century and are now UNESCO World Heritage Sites, making North Wales a must visit destination for history lovers.

Below are the top castles to explore in North Wales, each offering a unique glimpse into the past.

Caernarfon Castle

Caernarfon Castle is one of the most famous castles in Wales and a key landmark in North Wales. Overlooking the Menai Strait, this vast fortress is known for its distinctive polygonal towers and immense stone walls. It played a major role in Welsh and British history and remains the site of royal investitures.

Visitors can walk along the battlements, explore the towers and enjoy views across the water to Anglesey. Caernarfon Castle is ideal for families, photographers and anyone interested in medieval architecture.

Conwy Castle

Conwy Castle dominates the walled town of Conwy and is widely considered one of the finest medieval castles in Europe. Built in just four years, the castle is remarkably well preserved and offers spectacular views over Conwy Estuary and Snowdonia.

A visit to Conwy Castle pairs perfectly with a walk around the town walls and a stroll through the charming streets below. This is one of the best castles in North Wales for combining history with scenery.

Harlech Castle

Perched dramatically on a rocky outcrop, Harlech Castle is one of the most striking sights in North Wales. With sweeping views of Cardigan Bay and the Rhinogydd mountains, it is easy to see why this castle played such a strong defensive role.

Harlech Castle is closely associated with Welsh resistance and legend, including the famous song Men of Harlech. It is a powerful and atmospheric place to visit, particularly on a clear day.

Beaumaris Castle

Located on the Isle of Anglesey, Beaumaris Castle is often described as the most technically perfect castle of its time. Although never fully completed, its concentric design and symmetrical layout are considered a masterpiece of medieval military engineering.

Beaumaris Castle is flat and accessible, making it a great option for visitors of all ages. The nearby town and waterfront add to the appeal, creating an easy and enjoyable day out.

Criccieth Castle

Criccieth Castle sits high above the Llŷn Peninsula coastline and offers breathtaking sea views. Though smaller than some of the other castles in North Wales, its dramatic position and rich history make it well worth a visit.

The castle ruins overlook the popular seaside town of Criccieth, making it easy to combine history with a beach walk, café stop or coastal exploration.

Dolwyddelan Castle

Hidden in the heart of Snowdonia, Dolwyddelan Castle offers a quieter and more intimate castle experience. Linked to Llywelyn the Great, this native Welsh castle provides insight into Welsh princes rather than English rule.

Surrounded by mountains and woodland, Dolwyddelan Castle is ideal for visitors who enjoy peaceful locations and scenic walks alongside historical exploration.

Why North Wales Is Perfect for Castle Exploring

North Wales castles are unique because they combine history, landscape and accessibility. Many are close to each other, making it easy to visit several in one trip. Whether you are staying in Snowdonia, along the coast or on Anglesey, you are never far from a remarkable historic site.

Castles in North Wales are also open year round, offering a different experience in every season. Winter visits are quieter and atmospheric, while summer brings events, guided tours and family activities.

Planning Your Castle Visit

Most major castles in North Wales are managed by Cadw, the Welsh Government historic environment service. Buying a Cadw Explorer Pass can be a cost effective way to see multiple castles during your stay.

Comfortable footwear is recommended, as many castles involve climbing towers and walking on uneven surfaces. Always check opening times in advance, especially during winter months.
