Monmouthshire and Brecon Canal Towpath

Highlight • River

This flat and easy tow path runs along the Monmouthshire and Brecon canal, perfect for gravel cyclists, mountain bikers, walkers and runners.

Especially lovely in autumn with the changing colours of the trees, but really a great year-round trail.
