Crickhowell Castle ruins

Highlight • Historical Site

Crickhowell Castle, also known as Alisby's castle, dominates the views from the delightful market town. The now Grade I-listed ruin began life as a motte and bailey castle in the 12th century and was rebuilt in stone in 1272.

Harlech Castle

Highlight • Viewpoint

Against stiff competition from Conwy, Caernarfon and Beaumaris, this is probably the most spectacular setting for an Edward I castle in North Wales. All four are recognized as World Heritage Sites.
Harlech was completed from ground to battlements in just seven years under the guidance of the gifted architect Master James of St. George. The classic 'walls within walls' design makes optimal use of the difficult natural defenses.
Even when the castle was completely cut off by Madog ap Llewelyn's rebellion, it held strong – thanks to the 'Way from the Sea'. Via this path of 108 steps, which climbed steeply up the rock face, the besieged defenders could be supplied with food and drink by ship.
Harlech is easier to conquer these days. You can enter this amazing castle via an incredible 'floating' walkway.

Nestled on the banks of the River Tawe, this 40-acre (16 ha) Victorian country park is managed by the Brecon Beacons National Park authority and contains the Grade II-listed Craig-y-Nos Castle. The Castle was once owned by legendary opera singer Andelina Patti, today this impressive building is a hotel.

There are a few other accommodation options in the surrounding area, making Craig-y-Nos an excellent base for exploring both the Black Mountain to the north and the Ogof Ffynnon Ddu Nature Reserve to the east. Closer by, the park’s gentle paths and picturesque lakes are a delight to explore.

Hay-on-Wye

Highlight • Historical Site

Hay-on-Wye is an attractive, traditional and vibrant small town set in a delightful location on the Wales-England border. It has narrow sloping streets, a notable 13th-century castle and a world reputation for books! With over 20 bookshops for a population of just 2,000, Hay-on-Wye is often described as the ‘town of books’.

The town makes a fine stopping point on any long-distance walk or hike. Offa’s Dyke Path and the Wye Valley Walk pass through Hay-on-Wye, and the town is overlooked by the glorious Black Mountains to the south and by the green rolling hills of Powys to the north.

As it is easy to spend time browsing and purchasing items from the Hay-on-Wye bookshops, please remember that if you are on a long-distance hike you may have to carry the books that you buy!

Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

Went up on a beautiful crisp late morning hike from car park but could be nice to go from town of Llangollen

City of old white people. The whole thing has little to do with a romantic book village, antique shops and cafes characterize the townscape together with congested streets

a great castle to explore with views over the se and the Llyn peninsula. It has an informative video that explains its history and then a walk across the bridge that leads you through the fortifications. you can then explore all the rooms that have exhibits of the castles history within them. to finish off you can climb the tower to see the view. Great for kids as there is a park next to it and a cafe across the bridge to keep everyone happy. Parking is available on site but it is a small carpark.
