Britain's second-largest castle after Windsor, its concentric water defences and famously leaning south-east tower still dominating the town centre. The moat is now shared with resident swans and geese.
Worth the trip
The water defences and leaning tower, alongside the reconstructed siege catapults reviewers call the most impressive exhibits on site.
Before you go
There's a paid car park opposite the castle that fills up quickly, and the self-guided route is wheelchair and pushchair accessible.
Visitors are consistently struck by Caerphilly's scale and its dramatic water defences, with several calling out the views and atmosphere as highlights, and staff are repeatedly praised as friendly and helpful. A few reviewers note the ground floor is accessible but the upper levels involve a lot of steep, winding stairs, and one visitor felt the castle could use more artifacts on display inside. Overall the consensus is a rewarding day out, with some saying a few hours barely covers everything there is to see.
Britain's second-largest castle; famous leaning tower and water defences
“Nice castle with stunning views. I would expect to see more artifacts in the castle. The catapults were the most impressive exhibits.”— Georgios Adamakos, visitor review
