Bleak Llyn Llydaw lies to the side of Wales' highest mountain Mount Snowdon at 3,560' (1085m) , the long and narrow lake has formed in a cwm partway up the mountain, the steep rugged sides of Lliwedd overlook the lake to the south east with the long narrow ridge leading out to Yr Aran at 2,451' (747m) lying to the south. The name translates to English as Brittany Lake.
The lake can be reached via the Miners Track which leads up to Snowdon. The causeway across Llyn Llydaw was constructed in 1853 to facilitate the copper mining on this part of Snowdoni - prior to this horses and the extracted copper were carried across Llyn Llydaw by raft. The path skirting Llyn Llydaw and Llyn Glaslyn (now known as the Miner's Track) was constructed at the same time.
