Llwyn-on Reservoir

Highlight • Forest

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.

Lluest-wen Reservoir Dam Wall

Highlight • Structure

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!

Pontsarn Blue Pool

Highlight • Natural

Blue Pool.
At the bridge, head downstream on the right bank, following the path, to reach the Pontsarn Blue Pool. The path can be followed as far as desired beyond here, through the nature reserve. After some distance, there are a couple of paths leading up to the Taff Trail (such as one just before a weir in the river, 2 km downstream of the waterfall), which runs along the remains of a dismantled railway line.

The Taff Trail can be followed to the right, eventually crossing over the impressive Pontsarn Viaduct. 350 metres beyond there, a path on the left drops down to a footbridge over the river. On the other side, a path beside the river can be followed to the left, passing under the viaduct again, all the way back to the start of the walk.

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.

The Pontsticill Reservoir is filled by the Taf Fechan via the Pentwyn Reservoir directly upstream. It was built by damming the valley and completed in 1927. The aim was to supply drinking water for the increasingly populated area to the south. You can loop the reservoir for a nice gentle run or follow the longer Taff Trail up the western shore.
