A beautiful but freezing cold lake high in the mountains has been named the best place for in the UK.

Llyn Cau, in the foothills of has been ranked number one in a list of the best places to take a dip, free from the tyranny of chlorine and screaming children. Hidden high in the rugged peaks of Eryri National Park, Llyn Cau is a breathtaking glacial lake nestled in the crater of Cadair Idris, surrounded by 400-meter mountain walls.

"An epic place to swim, I recommend it to everyone! The initial walk is up some quite steep steps, but the scenery makes it worthwhile.

Another recalled: "With the sun on the lake it is wonderfully blue and clear. There are lots of places where you can walk straight in via the rocky beach, but three of us went for a more dramatic dive from a rock. A glacial lake and the mountain gives a stunning backdrop to a blissful swim on a hot day."
