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.

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!
