When coming off the mountain to go down towards the car park it’s quite a steep scramble and can be slippery

Area with nice views over the former reservoir, a couple of lost places and newly set up path and benches - an interesting mix of old and new and still in transformation.

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.

Lower Neuadd Reservoir is located in the Brecon Beacons, 5km north of Merthyr Tydfil in south Wales. The reservoir, which is an embankment dam, was constructed in 1884. It is the middle of a cascade of three reservoirs, with Upper Neuadd situated 3km upstream of the much larger Pontsticill Reservoir. Lower Neuadd Reservoir had a capacity of 195,454m3 with a top water level of 427.6mOD. Lower Neuadd Reservoir was no longer used for water supply and did not form part of Dŵr Cymru Welsh Water’s Water Resources Management Plan. Furthermore, there was concern regarding the age of the dam and the deteriorating spillway channel. Taking this into consideration along with the high cost to bring the dam back into safe operations and to comply with the Measures in the Interest Of Safety (MIOS), it was proposed to discontinue Lower Neuadd Reservoir.
