An interesting, easy walk through the Lledr Valley from Roman Bridge to Betws – as the crow flies – and one which is full of ancient history. Begin with a train ride from the busy town of Betws-y-Coed to the request stop at Roman Bridge. If the train isn’t running along the Conwy Valley – which was the case at the time of walking and writing, due to the track being swept away in the floods of early 2019 – it’s easy to take the replacement bus.
The route of this walk incorporates much of Sarn Helen, the Roman road local to the area. Sarn Helen actually refers to several stretches of Roman road throughout Wales. The full 160 mile route follows a meandering course through central Wales, and connects Aberconwy in the north with Carmarthen in the west, although debate continues as to its precise course. Many sections are now used by the modern road network and there are sizeable stretches that have been lost and are unidentifiable.
It’s worth allowing time to take a look at Dolwyddelan Castle along the way, reputed to be the birthplace of Llywelyn the Great. Built in the early 13th century, the castle functioned as a guard post along the main route through North Wales. This straightforward, direct route – the Romans loved straight lines – gradually descends to the spectacular River Llugwy, and continues over the steep and striking Miners Bridge. This is likely the same spot the Romans used to cross the river many centuries ago on their way to invade Anglesey and conquer the Druid stronghold there. The name evolved during the nineteenth century when local quarrymen used the bridge to reach the lead and tin mines of Gwydir Forest.
- From Roman Bridge station turn right and follow the single-track road as it winds downhill, and then sweeps to the right. Good views of Moel Siabod. Cross the stone bridge and continue up to a farmyard.
- Walk through the yard and turn right at the finger-post to join the Sarn Helen road. Where the track forks, keep right and continue walking until the castle comes into view. The track skirts the castle and continues to a metal gate. Go through the gate and walk to the end of the track to the main road.
- Turn left here, and walk a short distance along the road towards Dolwyddelan village. Turn right in the centre, along Church Street. Take the first left towards the station, passing the school to your left. Take the single-track road ahead.
- Follow the road to the end and pass through a metal gate into grazing land. Follow the track as it winds to the right beneath the railway line and then turn left to go through a gate. Continue along the driveway and turn left at the end onto a single-track road. Pass Pont-y-Pant station, then continue to cross the bridge onto the main road. Take the footpath opposite and turn left.
- Take the stile at the end to exit the path, and turn right along the single-track lane. The lane climbs steadily towards a metal gate – go through here and continue forwards along the rough track. At the fork bear right, then the way divides into three options. Ignore the righthand path, and ignore the lefthand path as it heads up towards a fir plantation. Take the less obvious middle path through the copse.
- Follow this route for about a mile until it passes through a gate at the end. Cross over the road at the junction to pick up a stony path as it heads downhill. Again, at the next junction go straight ahead on the track and continue downhill to a wooden bridge.
- Pass some large properties to the left and at the main road, cross over to take the footpath opposite through woodland down to the River Llugwy and the Miner’s Bridge. Turn right after crossing the bridge, and continue along the river bank into Betws-y-Coed.
