Llangorse Lake

Llyn Syfaddan

The largest natural lake in South Wales, with a medieval artificial island site in the middle, good for rowing, fishing and stargazing.

The lake is about 6 km around. On its north shore is Crannog, a rare artificial island built in the 10th century as the royal residence of the Kingdom of Brycheiniog, and a reconstructed hut stands by the lakeshore. You can hire rowing boats, kayaks or paddleboards, and there are climbing and horse-riding centres by the lake. The area is a dark-sky reserve, so clear nights offer excellent stargazing. It is about 10 km from Brecon.
