The river flows east after Llanbradach through a flatter wider valley before turning south again after Machen to Cardiff. We walk this section from Machen to Llanbradach. Past the preserved Machen Iron Forge and riverside path to Waterloo and through the Riverside Park at Trethomas to the old bridge at Bedwas.
