Llyn y Fan Fawr (Welsh for '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 (Y 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.
