Plynlimon and Wye Source Via

How To Get There

The mountain and source of the Wye is remote but accessible from anywhere in the UK. You can use public transport, which some of us have done. Again, see Vaga Story and these links to public transport.




Llandrindod to Rhayader & Llangurig Bus

This service is through to Llanidloes but stops at Rhayader and Llangurig. We have walked through to the source from here. It's a good walk and or hike that lends you an appreciation for the upper Wye. Buses back are from Llangurig or Rhayader.


Llandrindod to Aberystwyth X47

This service is through to Aberystwyth but is not as frequent. It will though take you closer to the source. A series of camps nearer to your hike into the Massif might be a good idea. It will introduce the area to you and be a great night out also.



Of course, bus rides back the other way depart from Aberystwyth. You need to be looking at the X47

Head for Eisteddfa Gurig either via Llangurig or Ponterwyd. Turn into car park run by the farm. Look for a good sign on the left if coming from Llangurig and the same if heading East from Ponterwyd.

Own Route Map & Description

Walk Guide  

There is a service track from the outset that runs adjacent to the Afon Tarennig, which is the route we take here although there is a second from here also that passes the Blaen Peithnant plantation (see Link). Again OS Explorer 213. It starts as you pass through the farm bearing right through a gate. Follow the Afon Tarennig for 200 meters until you get to a bend in the track at a junction between a feeder stream of the Afron Tarennig. Head right up the track adjacent to the mountain river. Stay on this track for 1700 meters then bear left off the track North - North West up a trail that steadily becomes indistinct. The turn left off the track is at a spoil dump and former lead mine. Easy to identify!

Once onto the mountain trail heading upward NNW almost diagonal admire the views around you. The trail will lead you up to Pen Pumlumon Fawr. To the right and front NNE as you walk up you'll see the sweeping space of the range that obscures the Wye. Like a big bowl it's punctuated by deep peat bogs that appear like black cakes in the distance.


As described in the Nant Y Moch walk the journey to the source is a short but invigorating one atop the Plynlimon mountain. From the summit trig or rock shelter there look East to the fence in your midst about 15 meters away. Follow it left until you reach the corner about 125 meters. (Grid Ref SN 791871). The remaining fence line that spans the top of the Plateau will lead you directly above the source of the Wye, which is approximately 1KM away along this fence line that actually runs slighty North East. Walking for the length of the fence you will pass a pool to your right and then another 280 meters further on just inside the fence corner (Grid SN 798872). This fence line heads right South East just before a standing stone with the date 1865 inscribed into it. This is a marker. It’s erect and you cannot miss it a few yards straight ahead of the fenced line and indeed worn trail you’ve been following.  From here trek alongside the fence until you hit a gate. Climb it, look North-North East along the fence that adjoins it and walk for approximately 150 meters away from it slightly. You’ll discover 3 gullies but you're heading for the furthest gully and longest, which is the official Wye source (Grid SN 803873) see link. Look for a depression in the ground that Robert Gibbins said was 'no bigger than a bowler hat.' Ahead of you is the wide-open space that signifies the embryonic Wye.

Every trip up is different. On the previous page and or route up from Nat Y Moch we were greeted by sweeping views West towards the sea and North towards Snowdonia and a glacial feature now filled with a Reservoir at Llyn Llygad. Here though were greeted by old Lead mines and views that look South and West as we ascend. It's all grand as we see Plynlimon or Pumlumon from different angles thus appreciating its extent.

Gear To Pack

Firstly, weather up here is unpredicatable in the latter part of the year specifically. It's the largest watershed in Wales and so it gets wet.  So, Pack a good water proof set. That's a jacket and trousers - if in summer a shell. Make sure also you have a good rain cover for your ruck sack (they're not totally waterproof and the lids have been known to drown). Inside pack a good map of the area and a warm insulating layer depending on the time of year.
