GPS Cycle and Walking Routes

Pontsticill Reservoir

7 miles (10.5 km)

This circular walk takes you around the beautiful Pontsticill Reservoir in the Brecon Beacons National Park. The reservoir is located a few miles north of Merthyr Tydfil on the Taff Trail. You can catch the splendid Brecon Mountain Railway to Pontsticill station next to the reservoir. The railway runs from Pant near Merthyr Tydfil along the full length of the Pontsticill Reservoir to Torpantau high in the Brecon Beacons.
The walk starts near the Dam and Pontsticill station and heads along the Taff Trail through a woodland area on the western side of the reservoir. You return on the eastern side, climbing towards Cwm Criban for splendid views of Pontsticill and the surrounding countryside. You then descend towards the dam and the finish point. The route runs for just under 7 miles and includes a moderate climb on the way.
You can extend the walk by continuing around Pentwyn Reservoir which lies just to the north.

At the southern end of the water you'll find the conveniently located Red CowInn. The limestone pub was traditionally constructed around 1840 and includes a cosy interior with a log fire. Outside there's a lovely beer garden to relax in if the weather is good. You can find the pub at a postcode of CF48 2UN for your sat navs.

Dog Walking

The reservoir and the surrounding woodland are ideal for a nice dog walk. The Red Cow Inn mentioned above is also very dog friendly.
