The 2021 Blue Flag beach awards for Wales show very many of these in the North Wales area. In Llandudno the West Shore beach is included as are Rhos on Sea, Llanfairfechan, Penmaenmawr. It looks as though Wales has done very well to get so many Blue Flag beach awards this year. I hope it reaps rewards with tourism.
