It's really easy to find. Park up in the side streets and walk through the park up the hill towards the lighthouse.
There are bolts at the top for setting up a belay, bring some long slings or rigging rope to extend them over the edge if you wish to set up a toprope (bottom rope).
As this is near a built up area, there was a small amount of broken glass on/around the crag, keep an eye out for it if you are taking your young children.
