About Llyn Geirionydd
Llyn Geirionnydd
A lake with power
Llyn Geirionnydd is a 3/4-mile long lake in Gwydyr Forest, and reputedly the home of the 6th century poet Taliesin.
Getting to Llyn Geirionnydd is not particularly easy, but this has not stopped the lake being the only one designated in Snowdonia to permit power boats and water skiing. Many visitors also walk to the lake from the village of Trefriw (it is on one of the Trefriw Trail routes) or from the neighbouring Llyn Crafnant (with Forestry Commission Wales car park), the two lakes being separated by Mynydd Deulyn – “mountain of the two lakes”.
Llyn Geirionnydd has a car park (toilets summer only) and is very popular in summer.
It is difficult to imagine that this was a derelict industrial landscape in the 1870s. In fact, the car park lies on a waste tip near an old lead mine entrance.
From here you can walk around the lake or if you are feeling fit, over to Llyn Crafnant and its great views, where you can opt to walk around that lake.
