Built primarily to regulate the flow of water in the River Severn, the Clywedog Dam is an impressive sight. It's the tallest concrete dam in Britain, at 236 feet (72 m) high, while it's also 750 feet (230 m) wide. There are two marked hiking trails on the reservoir.

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

Third highest summit in the Pumlumon range, Pen Pumlumon Llygad-bychan is perhaps most notable for its proximity to the source of the River Wye. To the north of the summit is the lovely pool of Llyn Llygad Rheidiol, while Pumlumon's principal summit is just a short walk along the Cambrian Way to the northeast. While the summit itself is not particularly distinguished and is known to be on the boggy side, it does offer lovely views across the Cambrian Mountains of Mid Wales.
