Please gather in Llan Ffestiniog at the Pengwern Arms (NGR SH 700419) at about 12.30 – 45pm.  Please have walking poles with you.

We have booked a light lunch (£13.00) at this community pub.  Please tell us of any dietary requirements.  Depending on numbers we might re-organise passengers and leave some cars in Llan Ffestiniog.

We will leave on the Dolgellau road, but turn onto the B4391 (Bala road) immediately after going under the railway bridge.  We will drive up to the car park overlooking the Cynfal waterfalls.   From there we can walk a short distance to the viewing platform and perhaps further, to view the area threatened for a fourth time by a hydro scheme.  This is not a very busy road, but please take care walking up and down it.

Return to the car park and drive to the Waterworks (SH 724426) and park cars off the track.

At the waterworks we will be met by Cathy Laws of the National Trust and will look at a copy of the Cantiorix Stone, found at Beddau Gwyr Ardudwy, a legendary site nearby.

We will then walk up the Roman Road to the base of Bryn y Castell.  Here we will look at a round building (Site A) used for iron manufacture in two phases, first Late Iron Age (c. 50 AD); the second in the 2^nd century AD, probably after the abandonment of Tomen y Mur by the Romans.  Access to Bryn y Castell is very steep so we will discuss the history of the fort from Site A, so that those who don’t want to climb can know what they are missing.
