9/9/18 - Headline co-ordinates have moved a little and the question has changed to reflect the new times on the new noticeboard. The co-ordinates are for both free parking and an information board that will give you the answers you need. Please take note of the closing times as your car WILL be locked in overnight. There is alternative parking in the nearby roads but please be considerate to the residents.
The information board lists the opening times of the car park in the following format:-
Summer 1 APR - 30 OCT
8.30am - A.BCpm
Winter 1 NOV - 31 MAR
D.BCam - E.BCpm
Final can be found at N50 54.CBA W001 03.AD(E+2)
