Llyn Y Fan Fach, Brecon Beacons National Park, Wales
Surrounded by rugged peaks, the Brecon Beacons make for a memorable wild swimming experience. If you are looking for an awe-inspiring place to cool down on a hot summer’s day, make for Llyn Y Fan Fach or one of the glacier lakes located on the slopes of the imposing Pen Y Fan. The whole area is crisscrossed with hiking trails, and the 7km Ystradfellte Four Waterfalls Walk is the ideal route if you are looking to combine a stroll with a swim. Enter wooded gorges as you follow the path of the Hepste and Mellte rivers and stop off along the way to swim in crystal-clear pools.
