Route Description

1. Swansea to Clydach

Following a mixture of riverside paths, new purpose build sections and old railway lines, this route provides a green strip through the industrial heart of the Swansea Valley. From the route it is possible to see some of the valley’s industrial past, while at the same time the route showcase its regenerated present. The ride begins in the re-developed marina, running alongside the Tawe and taking you up past the Morfa Retail Park and the Liberty Stadium.

2. Clydach to Ystalyfera

This is a very gentle 6.5 mile ride along canal towpath and old railway, following the valley floor from between two of the major Swansea Valley towns. Starting from Coed Gwilwm Park, the route picks up the canal towpath and takes you into the heart of Pontardawe. Moving away from the Canal and following the river bank, you find your way onto the old railway line. This takes you through woodland alongside the river before emerging on the edge of Ystalyfera. The ride can be halved in length if you stop in Pontardawe, while it can also be extended by riding in the opposite direction. If you are feeling particularly energetic it is possible to ride from Ystalyfera to Mumbles almost entirely on traffic free paths.
3. Ystradgynlais to Caehopkin
There is a short gap in the route after Ystalyfera but then the route continues to Caehopkin.
4. Llanwrtyd Wells to Builth Wells
National Route 42 is also open between Llanwrtyd Wells and Builth Wells.  This section is entirely on road
