Club information needed

Hi,does anyone know of a naturist club or say monthly meet/swim etc.,within a reasonable distance to the Llanelli/Burryport, Carmarthenshire area U K.I regulary use the unofficial nudist part of the beach inside Pembrey Country Park during the nicer weather but of course the U K weather being as it is I need an indoor area for mixed naturism during the colder unsettled weather,please see my profile and hopefully reply with the much sought after information,best wishes.
