February 25, 2026, Taff Trail: Nantgarw to Pontypridd

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

While on the Taff Trail the viaduct suddenly looms out of the trees, another fantastic example of the amazing construction skills of our industrial past, take a moment to stop and have a proper look.

This viaduct, near Treharris, to the southeast of Quakers Yard Station, runs over the River Taff. Constructed as part of Isambard Kingdom Brunel’s single-track Taff Vale Railway it connected Merthyr Tydfil to Cardiff docks. It and opened in 1841. This early railway bridge is 32.3m high, and has six arches of 15.2m span each with octagonal piers. Its westernmost arch passes over the former Merthyr Tramroad (completed 1802), now part of the Taff Trail (NCN cycle route 8). The structure is Graded II* listed ‘as one of the most remarkable bridges by Brunel to survive in Wales’.

The views around here are lovely on a clear day. The hills fold and bend, creating creases of patchwork farmland, meandering stone walls and some wonderful photo opportunities. You can see the bulk of Mynydd Eglwysilan as you hike south around the flank of Cefn Eglwysilan.

Part of Brunel's Taff Vale Railway, this viaduct spans the River Taff immediately south of Quaker's Yard station. The Taff Trail – a foot and cycle path – runs beneath, offering you a fantastic views of this historic bridge. It's still in use today, so if you're catching a train in the area, you might go over it too.
