Carmarthen Fans - the long mountain route
Llyn y Fan Fach sits beneath the precipitous ridgeline of Bannau Sir Gaer. It’s an epic scene, the remnants of the landscape’s glacial past clearly visible in all directions.
This must be a strong contender as one of the UK’s most dramatic walks, overlooking the glacial cirque of Llyn y Fan Fach on the western flank of the Brecon Beacons.
Often described as one of the most magical and breathtaking sights in all of Wales, Llyn y Fan Fach (Lake of the small Beacon hill), is a dammed lake in the western border of the Black Mountain – part of the Brecon Beacons National Park. To reach the lake, you need to prepare yourself for a bit of a hike uphill alongside a river, where the water continuously ducks and dips, forming sweet mini cascading waterfalls along the way. The rolling hills and nonchalant sheep are your landmarks, until you climb over the final ridge and become face to face with the lake. It's a truly awe-inspiring sight, with unspoilt panoramic views of the surrounding Brecon Beacons. It's yours to do what you want – have lunch, take a dip or just soak up the peace and quiet. As with most enchanting lakes, there's a certain legend connected to it.
Lady of the Lake...
A folklore legend connected with Llyn y Fan Fach is the myth of ‘The lady of the lake’.
In the folktale, a young farmer of the 13th century spotted the most beautiful girl he’d ever seen emerge from the lake, she was a princess from the kingdom of fairies. He courted the fairy princess by baking her bread and after 3 attempts he succeeded in winning her hand in marriage on the condition that if he hit her three times she would leave him.
He complied easily because she was so beautiful and they were happy for years bringing up a family at his farm near Myddfai, with her magic dowry of farm animals. In time the inevitable happened he hit his wife and she disappeared back into the lake taking her prized animals with her , leaving the farmer with her sons.
The sons once grown became known as the “Physicians of Myddfai” who became physicians to the English royal court.
