Llyn y Fan Fawr (Welsh: 'great lake (near) the peak')[1] is a natural lake in the county of Powys, Wales. It lies at the foot of Fan Brycheiniog,[2] the highest peak of the Black Mountain (WelshY Mynydd Du) range within the Brecon Beacons National Park. Created as a result of glacial action,[3] it is one of the largest glacial lakes in southern Wales.[4] 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.[5][6] Its primary outflow is to the River Tawe.[7] Much of the land around the lake is peaty and thus wet underfoot.
