Diamond Park and Ystradgynlais Railway Line

This is a pleasant and gentle trail taking you from Ystradgynlais, through Diamond Park, and along the disused railway line turned foot and cycle path beside Ystradfawr Nature Reserve.

This nature reserve is on the site of an old coal mine which has now become home to a variety of fauna and flora.

The trail is largely gentle and well-surfaced, but care is needed along the roads if out with children.
