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.

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).
