There are a few other areas, some pretty large, around the coast of South and West Wales that have potential for links golf courses if the current inhabitants/owners weren't there - some examples -
Oxwich, just west of Pennard
Llangenith/Llanmadoc - at the western end of the Gower Peninsula
Pembrey - the area that extends north from Ashburnham to Kidwelly, currently a Country Park, race track/airfield/MoD
Pendine Sands - currently caravans and MoD
Freshwater Bay, west of Pembroke, MoD again
Llanbedr/Dyffryn south of Harlech, includes holiday camp and runways (MoD?)
Harlech North, stretching north from RStDGC
West of Caernarfon, large spit on south side of mouth of Menai Straights. Runways so ex (still?) MoD
Newborough Burrows, Angelsea - area opposite the above on the north side of Menai Straights. Nature Reserve
The MoD influence from prior years is strong though, what with training areas, firing ranges, airfields.
