Pontsticill Reservoir

From Pontsarn to Ponsticill Reservoir

From Pontsarn, travelling North, we cross a narrow gorge on the the Pontsarn Viaduct then continue along the side of an interesting tree lined valley. A blocked tunnel entrance to the right shows where the railway track previously connected to Dowlais.

This section becomes progressively more rural as we notice the transition to the Brecon Beacons. It ends abruptly turning onto a tarmac lane under a bridge, then climb past water treatment works to the Ponsticill Reservoir.

Pontsticill Reservoir

This point on the Taff Trail is the eastern end of the Pontsticill Reservoir and dam.

It is also the point where a short lane will take you to one of the stations of the Brecon Mountain Railway. This is a narrow gauge railway however bicycles can be carried on request.

See for more information.
The Taff Trail runs across the dam, then north onto forest tracks of the Brecon Beacons. Some of these are very stony and cycling at speed is not an option.

The route to the south (after the first mile of road) is along the former Taf Fechan mineral railway, a well maintained traffic-free path.

The inscription says
When the 6-05 came through on The Brecon and Merthyr,
We knew it was time for tea.
