While on the Taff Trail the viaduct suddenly looms out of the trees, another fantastic example of the amazing construction skills of our industrial past, take a moment to stop and have a proper look.

A very pretty and accessible dam, the spillover makes it a lovely scenic addition to your loop of the reservoir or the nearby forest. There are lovely picnic areas on the way around the dam, some eating spots by way of a roadside 'scoff' van in a nearby lay-by on the eastern shore, and the cafe at Garwnant Visitor Centre on the north side of the reservoir.

This viaduct, near Treharris, to the southeast of Quakers Yard Station, runs over the River Taff.

This is a section of the Taff Trail NCR8 that is unpaved and muddy. Long may this last as the trail has important industrial archeological history. You can still see the stone seats that held the wooden rails of the old tramway in place. For more on the significance, Google Richard "Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive.[1] The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.[2][3] Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day. During the prime of his career he was a well-known and highly respected figure in mining and engineering, but near the end of his life he fell out of the public eye." - from wikipedia. - https://en.wikipedia.org/wiki/Richard_Trevithick
