Snowdon horseshoe from Llyn Llydaw by kronpano

Llyn Llydaw (welsh for lake Brittany) is one of the lakes you pass if you go from Pen-y-pas via the Miners track to the foot of Snowdon. This location makes it to one of the most visited lakes in the UK. It is up to 200 feet deep but it contains no fish; it is also considered to be one of the coldest lakes in the UK with 7°C and it is a candidate for an Excalibur lake (a lake from which Excalibur came and eventually returned on the mortal wounding of King Arthur - there are about 10 candidates but due to the location Llyn Llydaw is a quite unlikely one).

The causeway in the foreground was built in 1853 to replace the horse drawn rafts which transported the extracted copper from the copper works further up the shore. You can still see the remains of the old copper works if you follow the Miners track further towards Snowdon.
