The Brinore Tramroad runs for 8 miles (13 km) from Talybont-on-Usk to Trefil.  It was operational between 1815 and 1865 and linked the Tredegar iron works and Trefil limestone quarries to the Monmouth & Brecon canal at Talybont. Its route passes through the dramatic and scenic valleys of Talybont and Dyffryn Crawnon
​ before reaching the uplands of Trefil mountain.The Tramroad carried a variety of materials, primarily coal from the Rhymney Valley into mid-Wales, and limestone from the southern quarries for agricultural improvement. Its importance today is not only as an example of industrial archæology but also as a well used public right of way. Its hedgerows form a valuable wildlife corridor and it is frequently used by walking groups and lovers of the countryside because of the quality of its natural environment.
In Talybont, you can visit the Tramroad's canal wharf, where there is an information board and replica tram opposite the fine limekilns. The tramroad leaves the canal behind the White Hart Inn public house and is signposted.
