Highland View

Clun Castle is a ruined Welsh border castle on a rocky mound beside the River Clun, on the edge of the small, picturesque town of Clun. Founded shortly after the Norman Conquest, it still has its tall 13th century keep, which unusually sits on the side of the mound, along with extensive earthworks to wander around.

Tip: Wear sturdy footwear as the grounds have steep slopes and uneven ground; there is a free car park next to the castle, with toilets, reached by a footbridge with steps.

Hay Castle is a medieval fortification with a 17th-century mansion alongside, right in the centre of the book town of Hay-on-Wye. Founded by the Normans and rebuilt in stone around 1200, it has been attacked and burnt several times over the centuries.

Tip: Use the large public car park off Oxford Road, which has free electric vehicle charging points. Dogs must stay on a lead, and are welcome on the ground floor, in the café and in the grounds.

Aberystwyth Castle is a Grade I listed fortress on the Ceredigion coast, begun by Edward I in 1277 during the first Welsh war. It was built as a diamond-shaped concentric castle, with a twin-towered gatehouse and towers at each corner, and was finished in 1289.

Tip: Bring a windproof layer, as the castle sits right by the sea and the Welsh coast can be breezy and wet.
