For some reason the Duke of Devonshire feels the need to charge £6 to park in his carparks (and there's not really anywhere else to park if you have a youngster with you). You can use the ticket at any of the three carparks which makes a small difference but £6 is still daylight robbery. If I was doing a longer walk with the youngster in a carrier I would park out of the way somewhere and walk down instead.
