I cannot recall the name of the place at the moment. You take the south coast road out of St John to the east. It used to be a dead end, but I think there was a though road being built inlands a bit onwards toward Sussex when I was there last a few years ago. The old road ended at an old fishing community, now abandon that mght have been a national park property.
I took lots of nice images of the hand built sea wall of stones, to enhance the protection of the delta area of the creek and the remains of the the stages (docks) and piers. Nice gravel and sand bars full of driftwood and logs to walk up the freshwater crekk inland as well.
Sorry for the vagness.
