The Celtic Trail covers 377 miles, in its entirety of the most diverse scenery in Wales, taking you from the eastern 'Gateway to Wales' at the Severn Bridge, Chepstow, to Pembrokeshire Coast National Park in the West.

The Celtic Trail will take you on a scenic journey along largely traffic-free routes and offers the opportunity to experience the diversity of the Welsh culture, history and natural beauty. Travelling through the green valleys, once a famous industrial heartland, the Trail takes you along canal tow paths, disused railways, quiet country lanes, into forests, over mountains and through vales to Swansea, the city by the sea. There are many sites of historical and industrial importance along the route. This section also features the Taff Trail, linking Cardiff to the Brecon Beacons.

A Sustrans Celtic Trail East map is available to purchase which will include the full trail and its links into Merthyr Tydfil County Borough, this is available directly from Sustrans.
