    Hiking

    Zoe has given out a lot of the history of the dam. Let's just add a bit of local information to say that this is a hidden gem of a reservoir. Though well known by locals, it is still an under-visited location. There are lovely walks to be had either around it or through the adjacent forests, there is a cafe and a roadside service van with refreshments on the way around; and the trails are great. The forest views, quaint foot bridges, and views out over the water make it a very scenic area.

    Hiking

    Llwyn-on Reservoir (or Llwyn Onn Reservoir) is the largest and southernmost of the three reservoirs in the Taf Fawr valley in South Wales. Cardiff Corporation Waterworks obtained an Act of Parliament in 1884 to authorise construction of the reservoirs, to increase the water supply for Cardiff, but construction of Llwyn-on Reservoir did not start until 1911 and was completed in the 1920s.
