Llyn Stwlan

Llyn Stwlan

Stwlan Dam, at an elevation of 502m (1,650ft) above the sea level, located in the Snowdonia National Park, North Wales is the Power station at Blaenau Ffestiniog.

Starting in the city of Tanygrisiau, Llyn Stwlan is reached by a narrow 4,5 km winding road with six hairpins bends. At the top, the views of the Moelwyn range and the Vale of Ffestiniog are outstanding. Footpaths and a road (closed to cars) lead to Llyn Stwlan from Tanygrisiau, where there are car parks. 
The surface of the road is asphalt, and chains or snow tyres can be required anytime. Llyn Stwlan was a small, corrie lake until the late 1950s when the dam was built as part of the Ffestiniog Hydro-Electric pumped storage scheme. Lying 1500 feet above sea level in the Moelwyn mountains, Stwlan is the top reservoir from which the water drops 1000 feet to turn turbines at the Ffestiniog Power Station.
