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.

A walk on St David's Day, even if there was hail. Nice flattish walk ending with lovely sea views. Got a little lost in the estate coming back, and stopped recording at a point where I'll be retracing footsteps.

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).
