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.

Stokesay is a moated, walled manor house near Craven Arms. Though it looks like a castle, it was really a lightly defended mansion, with work completed by 1291. The stone hall and solar block sit behind two stone towers, and the hall keeps its 13th-century wooden-beamed ceiling. The timber and plaster gatehouse at the entrance dates from the 17th century.

Tip: Book advance tickets online through English Heritage, and finish with a break in the tearoom, which is open to all and welcomes dogs.

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.

Croft Castle is a castellated 17th-century manor house that has been the home of the Croft family for many centuries. Inside, you can look round the castle rooms, while outside there are colourful herbaceous borders, a secret garden and a walled garden with a small working vineyard, historic apple trees and a glasshouse.

Tip: Dogs on leads are welcome in the garden and parkland but not in the house. Satnav users should enter HR6 0BL, as the National Trust recommends.
