A river-and-waterfall road up into the Fforest Fawr geopark.
The A4067 runs up the Tawe valley from Ystradgynlais towards Sennybridge, through the waterfall country of Fforest Fawr past Craig-y-nos. It is a flowing valley road that climbs onto open moor at the top; mind the villages, the cyclists and the cavers' parked cars near Dan-yr-Ogof.
