Llyn y Fan Fawr (Welsh: 'lake of the big peak') is a natural lake in the county of Powys, Wales. It lies at the foot of Fan Brycheiniog,[1] the highest peak of the Black Mountain (WelshY Mynydd Du) range within the Brecon Beacons National Park. Created as a result of glacial action,[2] it is one of the largest glacial lakes in southern Wales.[3] The lake is roughly rectangular in shape with its long axis oriented roughly north-south.[citation needed]

The surface of Llyn y Fan Fawr lies at about 1815 feet or 605m above sea level,[4][5] its primary outflow is to the River Tawe.[6] Much of the land around the lake is peaty and thus wet underfoot.
