You can enjoy lovely views of the town and Afon Valley from this high up viewpoint on Pontrhydyfen Viaduct. The viaduct itself was build in 1898 by the Port Talbot Railway.

January 24, 2024, Herbert's Quarry

Herbert’s Quarry is part of the Black Mountain and Mynydd Myddfai Registered Landscape of Outstanding Historic Interest in Wales. Unlike in other lime producing areas where canals and tramroads could be built, the industry at Herbert’s Quarry was served solely by road transport. The lime trade was a factor in the development of Turnpike roads, and the network of tracks and roads over the mountain is closely associated with the activity at Herbert’s Quarry. As you walk through the site you are taking a journey through time, and walking in the footsteps of many hundreds and thousands of people before you, people whose hard work, sweat and drudgery shaped this landscape and left a rich industrial legacy.

Nestled along one of the finest driving routes in Great Britain, this spot is perfect for a leisurely picnic at the available benches or simply admiring the stunning views. Keep an eye out for the occasional ice cream van to add a sweet touch to your visit

Check out the Afan Valley Bike Shed - great helpful staff and they sell a selection of souvenirs - tees, hoodies, mud guards & stem caps (always good to support the local shop).
