Great photo opportunity, but the area can be busy depending on the weather and it’s likely any progress on a bike would be very slow. Early mornings and evenings are good.

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.
