Llyn Cwm Llwch is a small lake that lies below the highest peak in South Wales called Pen y Fan, which is situated in the Brecon Beacons of Powys and is the setting for some rather strange legends which are briefly presented here. The first tells how an old woman who lived in the lake used music to lure those of a weak or impressionable mind into the water to be drowned. Tradition says that when she has claimed nine hundred victims she will regain her youth and beauty and gain immortality.
The Door to the Invisible Island
Another legend tells that there is an invisible island in the lake that could only be reached by a door that was set in a rock. Every May Day the door would open and some of the bolder local people would enter and pass down a passage that opened up in a garden that was set upon the island. Although the shores of the lake could clearly be seen from the island, the island remained invisible to those on the shore.
The Enchanted Garden of the Tylwyth Teg
Those who entered the door and visited the invisible island found themselves in an enchanted garden. This garden was filled with the most beautiful flowers of the most wonderful colours and trees hanging with luscious fruit ripe for eating grew all around. Beautiful birds sang happy songs in the trees and butterflies flitted between the flowers. It really was a most enchanted place.
