Discover Dol-y-gaer

Located in the south of the Brecon Beacons, this stunning landscape amongst the rolling hills frames both Pen-twyn (Dol-y-gaer) and Taf Fechan (Pontsticill) Reservoirs. 

It’s steeped in history with an Iron Age hillfort and Bronze Age barrow amongst just some of the sites still visible in the landscape.

There was once a working station (1863 – 1964) serving the hamlet of Dol-y-gaer which is now part of Plas Dolygaer Scouts Centre and Campsite, next door to Parkwood Dolyager Activity Centre adjacent to the Taff Trail (NCN Route 8).

The Merthyr Tydfil Boating Club regatta came off at Dolygaer Lake on Thursday, last week. The weather was very auspicious, it being bright, sunny, and warm, and convenient arrangements having been made for the running of trains on the Brecon and Merthyr Railway, there was a vast concourse of people at the lake early in the day. Trains were also run from Brecon, Cardiff, and Newport, and altogether it was calculated that there were about 8000 present.
