Having a look at the map No9 should be the `Port Dooker' and not `Cooker' and should be up from the new bypass bridge, just down from the Rays.
In case you don't know what a Dooker is, it is somewhere you went for a Dook, hope this helps.
As Sandy has said above the car park is above the Rays Hut and there is also one above from the Boat pool, but as they are passing places (they have been extended though) I am never 100% sure that we should be parking in them. Latterly I used to leave my car in Upperboat Road, beside the bridge, and just walked up the beat.
There should be a new car park built for walkers & fishers beside the new houses, at the other side of the bypass from the Hospital, but I have never been down there this season to see if it is there yet.
Regards,
Bri.
