Another plan for the future . . . we want to extend the route west to the first home of the monks who eventually settled in the Conwy valley. They first lived at a place called Rhedynog-felen, somewhere near Clynnog-fawr at the top of the Lleyn Peninsula.
It should be possible to walk from Trawsfynydd along the line of the Roman road and down to Blaenau Ffestiniog and Tanygrisiau. Follow the road up hill through Tanygrisiau. At about SH 68410 45338 it becomes a stony track up Cwm Orthin. Cross to the west bank of the stream when you can. Cwm Orthin was a little slate quarrying settlement, now completely deserted but with somespectacular ruins of quarry buildings. Cwmorthin had not one but two chapels - in Wales we always need a chapel we don't go to. More on all this at http://www.cwmorthin.com/ .
Follow the track up the incline to the quarry buildings and turn right across the big paved area. After the main buildings, at SH 66440 46245 a footpath goes left, over the ridge and down to Croesor. The path becomes a metalled road. At SH 63197 44618 turn right. This minor road becomes a track over the shoulder of Cnicht. Bear left at SH 63197 44618 and walk down to the road. Take the minor road opposite and follow it across the linke of the restored Highland Railway. Turn right on the main road, bear right again on a lane at SH 59676 46177, rejoin the road at SH 59461 46255 and take the footpath to the right before the bridge. This follows the railway line up to Beddgelert.
From here a footpath goes over Bwlch Meillionen to Cwm Pennant and Garn Dolbenmaen. Walk through the lanes to the possible site of Rhedynog-felen, a farm called Mynachdy Gwyn, the White Monastery, at SH 44115 45737.
Here the Cistercian Way links with the Edge of Wales pilgrim path to Aberdaron and the holy island of Bardsey. Or you can walk along Lon Eifion, a cycle and pedestrian track along an old railway line to Caernarfon and the coast path.
