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.

Fellow hiking friends have said that this lake has a lot of leeches! 😳

I have been coming up here now for about forty years. There are a variety of routes to here, but each one brings you to this one spot. These lumps of stone and the views are drop-dead gorgeous. Top it off with a visit to the pub afterwards, and it's a good day out. It's also a good run—before you get to the pub, of course!

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.

A fantastic long, slightly downhill gravel stretch high above Talybont Reservoir, this trail delivers both in terms of adrenaline and views! The track is wide and mostly quiet, though the gravel can be loose and a bit chunky in sections, so a gravel bike, sturdy tourer or mountain bike is best.
