Llyn Llydaw (from the Welsh meaning Brittany lake) is a natural lake in Snowdonia National Park on the flanks of Snowdon, Wales' highest mountain. This long thin lake has formed in a cwm about one-third of the way up the mountain.
Its special significance is that it is one of the most visited lakes in the United Kingdom. Thousands of people every year visit Snowdon and many walk past this lake on the Miners' Track.
Llyn Llydaw is the largest of the three lakes on Snowdon's eastern flank. Higher up lies Glaslyn, and lower down lies Llyn Teyrn.
The lake featured in Robson Green's Wild Swimming Adventure (ITV December 2009), chosen because it is allegedly the coldest lake in Britain. Green's website states that the water was 7 degrees Celsius, but other Welsh lakes are often colder than this.
