5 Best Castles In Monmouthshire and Gwent
Five castles, and what separates them is how much is still standing. Caerphilly Castle and Chepstow Castle are big enough to lose a child in, with towers, curtain walls and water to look at. Raglan Castle is grand and roofless. Caldicot Castle, recorded with free entry, sits in grounds you can put a blanket down on. Abergavenny Castle & Museum is the shortest visit of the five and pairs its remains with a museum, which is often the better shape for a short attention span.

Steps are the thing to settle before you set off. Any castle worth climbing comes with spiral stairs, uneven ground and a few drops, so bring a carrier and save yourself the shepherding. If you want one castle to serve the whole family, the larger sites give older children room to explore while there is still level grass for the youngest. The small ones ask everybody to be interested in the same thing at the same moment.
Castles in Monmouthshire and Gwent: FAQs
Which of the five suits young children best?
Caldicot Castle makes the gentlest introduction. Its grounds count for as much as its walls, so the youngest get grass to run on instead of gravel and stairs. Abergavenny Castle & Museum can be finished before anyone melts down, and its museum room is a useful bolt-hole once the weather or the mood turns. Caerphilly Castle and Chepstow Castle are more rewarding and more work.
Is one castle enough for a day out?
For most families, yes, and stacking two into an afternoon is the classic way to ruin both. A large site like Caerphilly Castle will take a good chunk of a day if children are allowed to explore it at their own pace rather than being walked round it. A smaller one like Abergavenny Castle & Museum genuinely is a shorter visit, and pairs better with something unrelated afterwards than with a second lot of walls and interpretation boards.
Do these work in bad weather?
Only partly, and the records here need reading carefully: all five are marked as having both indoor and outdoor space, but at a ruined castle the indoor part may be a gatehouse, a shop or a single vaulted room rather than a wet-day plan. Abergavenny Castle & Museum is the one with a proper indoor element in the museum. For the others, assume you are outside for most of the visit and take waterproofs rather than an umbrella, because castle walls funnel wind.
How do you choose between two big ruined castles?
By what a child can physically do there. Some sites are about the footprint, where the pleasure is in crossing a huge site and seeing how far the walls go, and others are about height, where the pleasure is climbing a tower and looking out. Caerphilly Castle and Chepstow Castle offer different versions of that. Where a child dislikes heights, the better day is at whichever one lets them stay on the ground and still feel they saw the lot.
