Laura asks if anyone recognises where this is. The children are her brothers and sisters.
My guess is that it is the rock visible in the distance beyond house #29 on the left edge of this photo:
It would be somewhere near their house, so they'd know it well. And if you walk south from house #29 to the coastline and then look east, you should see the peninsula shown in the main photo above.
Can anyone confirm?
