This is a great section of NCN 4 which crosses over the River Neath parallel to the elevated M4 motorway. It's quite an industrial stretch but the views are great, and the cycle path is segregated from the road.

The northernmost and highest of the three reservoirs in the Taff Fawr valley.

Riding the Sarn Helen from the start at Ynysygerwn is a technical climb. I would say probably not ride-able on an analogue bike but completely possible by EMTB.

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%.
