Llyn Llydaw is a beautiful natural lake located in Snowdonia National Park in Wales. Its name comes from the Welsh language, meaning 'Brittany lake'. This long, narrow lake sits on the side of Snowdon, which is the tallest mountain in Wales. It formed in a special type of valley called a cwm, about a third of the way up the mountain. Llyn Llydaw is very popular, attracting thousands of visitors each year. Many people walking the famous Miners' Track to Snowdon's summit pass right by this stunning lake.
Discovering Llyn Llydaw
Llyn Llydaw is the biggest of three lakes found on the eastern side of Snowdon. If you travel higher up the mountain, you will find Glaslyn. Below Llyn Llydaw, closer to the valley, is Llyn Teyrn. These lakes are all part of the amazing landscape of Snowdonia.
Power from the Lake: A Look at its History
In 1905, something very important was built at Llyn Llydaw. Engineers created a pipeline that stretched for about 2 kilometers (1.2 miles) from the lake. This pipeline carries water down into the valley below.
The water from Llyn Llydaw powers the Cwm Dyli hydro-electric power station. This power station is located 320 meters (1,050 feet) below the lake. Hydro-electric power uses the force of falling water to create electricity. It's a clean and renewable way to generate power. Both the pipeline and the power station are still working today, more than a hundred years later!
