Lluest-wen Reservoir was constructed in 1898, but came to national attention in 1969 when a major leak caused an evacuation of residents down-valley while emergency repair work was carried out. Back in 1929 the place set a maximum daily rainfall record for Wales, with 211mm of rain recorded. You have been warned!

Cwm Clydach Countryside Park is an oasis of calm for wildlife with stunning views that has been created from the blackened scar of a coal mine. Walking alongside the lakes offers the chance to spot Kingfishers, herons, butterflies, newts and more.
