Dol y Mynach’s foundations were built during Phase One of the scheme, and were to be completed in Phase Two, along with two more dams in the Claerwen valley at Ciloerwynt and Pant y Beddau. After World War II, technology had advanced to build one much larger dam, the Claerwen.
You can walk down to the dam and see the large stones used inside the structure (known as plums) or visit the bird hide. Ospreys have been seen, along with other birds such as Crested Grebe. The reservoir itself is a Site of Special Scientific Interest (SSSI).
A tunnel runs from Dol y Mynach to Garreg Ddu reservoir to fill up Garreg Ddu if needed. Dol y Mynach is the only dam without hydroelectric turbines.
Enjoy the tranquillity of Dol y Mynach reservoir and see if you can spot any of our feathered visitors, from blue tits on the feeder, to Great Crested Grebe.
A short (15km), moderate route that takes you around Caban Coch reservoir which should take about an hour to complete.
