The next section of our Cambrian Way walk started from the Upper Blaen-y-glyn car park, above Talybont reservoir.  The first task was to complete the short CW link from the Pontsticill road to the path heading north to Craig y Fan Ddu. This was to avoid having to do it on the next CW walk. We headed eastwards on the Taff Trail – hearing our first cuckoo of the spring – before cutting off towards Pen Rhiw-calch and then up to the tramway, where Ceridwen pointed out the remains of an old Roman bridge. Down into the Dyffryn Crawnon valley and up Cwm Pyrgad to the Nye Bevan memorial, where we joined the CW. This section of the CW crosses the rough upland to the Pant y Creigiau trig and then down to the cars.  Excellent weather with light cloud and sunshine – but not too warm.
