February 25, 2026, Taff Trail: Nantgarw to Pontypridd

Always a nice ride across this section. Great views, but can be mucky in the winter.

A remnant of Merthyr's past. This bridge carried a railway line that either took you through a tunnel to Aberdare or sent you north towards Cefn Coed and on to Brecon via Torpantau. Under the bridge was the Merthyr to Cardiff Glamorganshire canal which carried the produce of Cyfarthfa iron works to the ports of Cardiff which was then shipped all over the world.

The white noise from the crashing water makes this a perfect place to tune out of the world. Unique place!
