Caerphilly Castle

Caerphilly Castle is the largest castle in Wales and one of the most impressive medieval fortresses in Britain, managed by Cadw in the town of Caerphilly, a short distance from Cardiff. Dogs on leads are welcome to explore the ground floor throughout the site — including the vast courtyard, the north dam platform and the great hall, which has recently reopened following a major regeneration project and now features new digital exhibits. Upper floors, towers and staircases are for assistance dogs only, owing to steep and narrow medieval stonework.

The castle is a genuinely immersive visit at ground level: atmospheric halls, concentric defensive walls and a moat-ringed setting make for a substantial outing. A pay-and-display car park is available on site, with dedicated accessible parking.

Opening hours vary seasonally; the castle is closed on 24–26 December and 1 January. Admission charges apply, though Cadw members enter free. Geese nest around the moat in spring and may be aggressive — keep dogs close during that period.
