Wales - Llyn y Fan Fach, Brecon Beacons

A high lake in the shadow of the Black Mountain, Llyn y Fan Fach sits in a sheltered bowl with stony, gently shelving sides. Reaching up to 18 meters in depth, it's the perfect spot for diving and practicing your underwater swimming technique. Located in the Brecon Beacons National Park, Llyn y Fan Fach is breathtakingly beautiful and according to legend, the home of a lake nymph.
