The Cefn-coed Viaduct is the third-largest viaduct in Wales. This huge, curved structure once carried the Brecon and Merthyr Tydfil Junction Railway and is now part of the Taff Trail, which is Route 8 of the National Cycle Network that runs between Cardiff and Brecon. It offers walkers and cyclists a superb view of the Taf Fawr as it cascades over the many weirs in the valley

Cefn-coed Viaduct was built in 1866 and is 770 ft (235 m) long and 120 ft (36.6 m) high. It is a rusticated-limestone structure of fifteen arches, set on a curve. The tall, slender piers and parapets are constructed with coursed irregular sized rock-faced limestone blocks
