Belfast Castle BT15 5GR for Cave Hill
Approaching Belfast on M1, continue on to the West Link and take the turn off signed Crumlin Road Gaol, City Centre (Clifton Street) and Mater Hospital. At the traffic lights at top of the slip road turn left and drive 100 metres to Carlisle Circus roundabout, taking the third exit on to Antrim Road. Drive approximately 3½ Km (about two miles) up Antrim Road; you will come to a Brown sign to Belfast Castle on your left - follow this sign into Innisfayle Park and towards the top of the Park, at the crossroads, you will see the gates to the castle immediately ahead. Continue through the gates, up the drive to the castle and park in one of the car parks - either just before the castle (on your left) or in front of the castle itself.
Other options are available if these are full - drive past the castle through the gates and pick a parking spot on the exit road..
