Llyn Clywedog was the Tallest in the British Isle built purposely to control the level of water to help prevent any future flooding from the source of the River Seven. By Building this absolutely incredible huge 6 mile long dam, one that was the tallest in the British isles, which is amazingly huge in actual size all around! This mammoth body of water is solely to take the huge pressure off the constant mass of floods which would fill up and submerge the surrounding valleys! At the foot of the dam there is a remains of a old lead mine! All structures you can see standing still today. HIGHLY RECOMMEND

The red kite is seen in the area, along with many other birds, plants and animals. There are numerous footpaths, and many bridleways that are popular for mountain biking and horse riding.
