"A tremendous feat of Victorian engineering, and it's a marvel to view. However, the views from above are just ok.
It connects well to the Taff Trail"
Joe Macpherson
"The viaduct is part of a disused railway, and forms part of NCN8 / The Taff Trail. It is breaktaking to travel on top of. It is well-paved and very wide. The views over Merthyr Tydfil are great in both directions."

"I walked this once in the snow as you can park up in a layby on the A470 which is normally fairly passable in snow. The snow transformed the views and it felt you could be in an Alpine scene, not looking over various parts of Merthyr Tydfil.
An impressive structure and part of a much larger part of trails and cycle paths this is definitely one of the high points - literally and figuratively - of the Taff Trail. If you get the chance to visit in the snow then take it."
