River Seiont and Caeathro from Caernarfon

An easy walk, or off path run from Caernarfon WHR station. As I’m training for a trail half, any opportunity to get off road is welcome.  Apologies for the images as it seems my mobile is useless at taking images in these conditions.

The Route

Starting from the WHR station in Caernarfon, you follow the Lon Eifion Cycletrack for about 800m.  When you pass under a road bridge and there’s a pedestrian crossing of the railway, take it and follow the path downhill.

You pass under another road bridge and walk along the riverside and through an arhced passage in the much older road bridge of Pont Saint.

You can only follow this for a short distance, before you have to walk on the quiet tarmac lane towards a cul de sac of unexpected houses.

Follow these to the very end and there’s a footpath sign to the left past the houses and along a tarmacked path. Just beyond you’ll pass under another bridge and on average, you’ll have to duck as the passage is very low!

The route is easy to follow as you’re on the riverbank, initially on a man made track to the side, then a muddy footpath for most of the remainder. The walk is much more pleasant in the summer than the bleak photos below suggest!

The low point of the walk is passing a disused brickworks along a concrete path which leads to the Caernarfon-Beddgelert road. You follow the road on a good pavement for a couple 100m and turn right down a green lane like footpath at the sign. It was rather muddy today.

At the end of the lane, the footpath crosses a couple of fields. The first is at about 45 degrees to the field boundary towards a clear gate in the wall (it’s clear once you see it!!). The corner of the field was particularly wet today, though no mud was apparent, my trainers tell another story.

Continue in roughly the same direction across the field, there’s no path, to another gate. This one seems to be flooded, so not a walk to do in the wet unless you wear boots. Finally, across the last field takes you to a minor road on which you turn right. If you feel thirsty, then you can always turn left into Caeathro where there’s a pub (check opening hours) and a large garage.

Keep on the lane and take the first right along a narrower lane and keep on that for a 1.5km, bringing you out on the A487. Turn right along the wide foopath and again right where the path now crosses the Afon Seiont via Pont Saint.

Just over the bridge, there’s a left hand turning down a slaty track and you’r back on the route you followed out. You soon cross the railway and arrive back at the start via Lon Eifion.
