Embalse de Negratín Naturist Beach - Cuevas del Campo- Spain

Hi!Embalse de Negratín Naturist Beach - Cuevas del Campo- SpainI wondered if anyone has been to this inland beach and could share any info. It seems the local mayor is actively promoting it but I cannot find any information on the internet as to the precise location or directions. Thanks to anyone who can help.PS:  Sorry I put this in the resort section I should have put it in the European Locations one!!
