Taking In the Source of the river LLynfi

 

Starting at LLangasty Village Hall beside LLangorse Lake, the Lynfi Trail is a varied walk that takes in the source of the River Lynfi, a Wye tributary that flows through LLangorse Lake and enters the Wye at Glasbury. The walk is packed with views from the top of Alt-Y-Esgair and Cefn Moel. The source of the Llynfi is a fairly enchanting marsh at the foot of Blaenllynfi Castle, which is maybe why it was built there in the 12th Century to guard the pass/Bwlch. There are some good remains.

 

Missing out the summit of Mynydd LLangorse on Cefn Moel, down below the route passes St Gastyn church at Llangasty Talyllyn, the first church of which was built in the Dark Ages. A short distance away, we hit the southern shores of LLangorse Lake, formed 10,000 years ago during the last ice age. The route is in and out like a concertina. You're not likely to get bored on this one.

​

Section 1

​

Start at the LLangesty Village Hall south of LLangorse Lake. The infant Llyfi is already flowing to the east into the lake. Stepping onto the Alt-Y-Esgair path next to the village hall it's a steep start onto the ridge. The path is fairly easy to follow as you're soon handrailing a boundary to your left. Views of the lake open up very quickly as do views of Mynydd Troed, Mynydd LLangorse and the central Brecon Beacons. At the summit the tops of the Black Mountains can be viewed over the top of Mynydd LLangorse and  Cefn Moel to the east. 

​

Section 2

 

Keep handrailing the boundary on the ridge and descend heading for the Roman Road further south marked on the map. As you descend the landscape shifts opening up the Usk valley to the south. Clearing the ridge and crossing open ground with Middlewood Fm below left, you're soon walking the Roman Road - now a path resembling a drovers route. Meeting with the lane the route bears left for Castell Blaenllynfi. As you come to the T-Junction towards the castle note the stream in front. This is the Embryonic Llynfi.

 

Turning at the Junction we bend around until we reach the 12th Century fortification - a wooden gate to your right marks the entrance. There's a picnic table in the woods surrounding the castle. As you enter look left - there the marsh is wet running beneath a culvert. This is the source of the river. 

​​​

Section 3

 

Leaving the castle and the source turn left back the same way you came and turn right at the corner of the road down an old bridleway/path. This cuts out most of the road section. Emerging out on the road bear left and then almost immediately turn right heading through Heol-las Fm. Follow the route through the plantation and onto Cefn Moel. Bear left on the eastern side as if walking towards Mynydd Llangorse.

Summary

​

With well laid out tracks initially locating the pools later can get tricky - it's fairly featureless. Mind you with pacing, observing your grid ref and possible use of a compass it's fairly easy. The whole area is remote and not your tourist hot spot. Views of Beacon Hill ac company you and when you hit the ravine it gets even more interesting. As a landscape feature it's spectacular.

Hiking Into The Range

The route in from Knighton is a full 13 miles. You need to be fit and used to hiking them distances with a wild camp and exploration of the source/range in addition. The best way is to pick up the Glyndwr's Way from Knighton - see full map on LDWA link. It will take you right passed the source and a plantation with some reasonable pitches inside if not pitching on the hills.

​

If wild camping always treat the space with respect. Be kind-leave no trace. For more on Wild Camping click here.

 

From Llanbister Road station, which you can pick up from the South West at Llandrindod Wells, Builth Rd (ETC) or from the East  at Craven Arms or Knighton on the Heart of Wales Line it's less than a 2 mile walk to Llugwy Farm at the base of the range. A good option!

Conservation

Throughout the range that feeds both the Lugg and Teme Heather has been lost to Bracken. To combat this the Powys Moorlands Partnership is undertaking works to weed wipe the area whilst brash marks aim to manage the heather. This is to help wildlife and the resurgence in heather. Dew ponds and other initiatives are also being undertaken. For more click here

We mention Radnor Forest but there is also Beacon Hill a watershed of the Teme in the range to alongside Stanky Hill, which feeds the river Aran then the Ithon another main tributary of the Wye. There are tumuli in the area on the summits of Rhos Crug and a nature reserve owned and managed by  Radnorshire Wild Life Trust on Cnwch Bank, which the Heart of Wales line passes through.

Towns In The Area

 

Knighton is the only town on the river Arrow. It's a Shropshire/Powys market town that was built upon Wool. You'll find it 12 KM as the crow flies from the source of the river. It's a decent start point if hiking in on the Glyndwr's Way. Other towns in the area are Rhayader further West at the foot of the Cambrian Mountains, Kington on the Powys/Herefordshire border and Llandrindod Wells South West from Llangunlo. All offer refreshment, shopping and great walks.
