NCN43 follows old railways lines, riverbanks and canals from Swansea to Clydach. This section follows an old railway line, it's flat and gravelled, easy riding but pretty and no cars.

This road is a firm favourite with those who know it - which is surprisingly few. Enjoy the spectacular views across the Brecon Beacons and Carmarthenshire Fans, with good quality tarmac under your wheels and only occasional car traffic. The approach from Trecastle to the North is about a 7km climb, with an elevation gain of 259m, and an average gradient of 3.7%.
