Can you reach any castle in Ayrshire by train?
2 of the 10 sit within 1.5 miles of a railway station, namely Dean Castle (Kilmarnock, 0.8 miles) and Kelburn Castle (Fairlie, 1.2 miles). Those are straight-line distances from the station to the castle, so the walk on the ground is longer than the figure.
Can you go inside every castle in Ayrshire?
Not all of them on the same terms. 2 of the 10 restrict what a visitor can see. Glenapp Castle is a hotel, so there is no way in without booking a room or a table. At Portencross Castle you get the grounds or a booked tour rather than free run of the building.
