Can you reach any castle within 40 miles of Cardiff by train?
14 of the 36 sit within 1.5 miles of a railway station, the closest being Newport Castle (Newport (S Wales), 0.3 miles), Chepstow Castle (Chepstow, 0.3 miles), Caerphilly Castle (Caerphilly, 0.3 miles) and Swansea Castle (Swansea, 0.3 miles).

Can you go inside every castle within 40 miles of Cardiff?
Not all of them on the same terms. 8 of the 36 restrict what a visitor can see. Thornbury Castle and Craig-y-Nos Castle are hotels, so there is no way in without booking a room or a table. At Hensol Castle, Newport Castle, St Donat's Castle and Cyfarthfa Castle you get the grounds or a booked tour rather than free run of the building.
