Returning to the WVW it descends to a lane where we turned R and took the bridleway track L that winds uphill to the ridge and peters out at 964634. A short climb through bracken leads to an easy grassy ridge that ascends gently to the trig point on Y Gamriw, accompanied by a windshelter complete with doorway and lintel. We walked W then SW to the remote Llyn y Ferlen and climbed gently to Gorllwyn. The next section was familiar from our previous visit to this area and the going gets a little rougher. Picking our way SW then NW we continued on easier ground to Carreg yr Ast and Drygarn Fawr where we pitched early and relaxed.

Descending S to the head of the Afon Gwesyn a good path develops down the E side of the river with its delightful tumbling waterfalls and rocky outcrops. A farm track is reached which ascends a little to Trysgol, drops R to the trees and leads out to the minor road. Turning R a short way there is a public toilet with hot water and litter bin standing by a solitary building.

Continuing on the road to 849518 a bridleway leads off R which heads SW along the R side of the valley to the minor road above Llyn Brianne. This undulates SW above the reservoir arriving first at the dam (public toilets marked on the map but we didn't check them out) and then the car park (788470) at the entrance to the RSPB reserve of Dinas, the conical hill ahead. The reserve building was closed but from the car park we took the path through the wood to the beautiful Tywi river which it follows round the base of Dinas then diverges E back to the road. Walking W on the road we crossed the river to Gallt y Bere and took the lane which flanks the Afon Doethie to Troed-rhiw-ruddwen 772479. From here a good path heads up the wild Doethie valley and we collected very good water at a side stream on the R, of which there are several. The valley sides are steep but we found a good flat pitch spot in a loop of the river.

Continuing up the valley we followed the obvious path which descends a little to the river but the map shows the bridleway ascending through the trees. After some head scratching we found our way to the correct line NE steeply up the R side of the Nant Lluest-fach, which gave good views back down the valley. The path becomes a track that later descends to Soar y Mynydd along the top of an embankment (the line on the map goes beneath the embankment and is basically an enclosed bog). From here a pleasant minor road meanders NNW along the Camddwr valley to 762576 and a waterfall.

A bridleway track sets off to Nantymaen farm and leads NW then N to Garn Gron where the trig point and large cairn lie to the L. The track gives up at this point and we descended N to the forest edge to locate the entrance point of the bridleway at 741628. This leads N without problems until the R turn just before Talwrn at 744648, where the line E did not fit the map. However it was fairly easy to locate an access track that led to the minor road, where we turned L to Strata Florida. The public toilets marked here are not quite public, they are accessed by key obtained when you pay the entrance fee to the Abbey ruins. The lane E is the start of the Teifi Pools Walk marked on the map which we followed to Llyn Teifi, collecting water at a stream in the cwm part way up. Flat grassy ground made a good pitch just below the lake .

Dawn brought a magnificent sunrise over the lake. Taking the metalled byway around the N end of Llyn Teifi and Llyn Hir we turned back S on a side branch along the W shore of Llyn Egnant to arrive at the dam and the start of the bridleway ENE.

The initial direction through this somewhat confusing terrain is not obvious but in about a quarter mile, having skirted Bryn Llyn Egnant, the line can be seen ahead contouring the R side of the shallow valley. The bridleway arrives at the river and there is no bridge. The river is wide and slow here but after hunting around a little while we found a way across by island hopping. From here it is an easy and pleasant walk along the Claerwen reservoir track to the SE end. A short way down the road a bridleway track branches L to climb E to Llanerchi Wood and descends to the road bridge between Garreg-ddu and Caban-coch reservoirs.

Crossing this and turning L, we saw the track by the shore marked on the map that terminates after a short distance, so we took the road. Arriving at the start of the bridleway E (914658) we noticed that the track actually went all the way along the shore and there was an access point here!. A good path climbs steeply E by the ravine of the Nant Dolfolau to a broad saddle then descends down another attractive cleft of the Nant Madog to arrive at the minor road head. Taking this to the B4518 and crossing it, we found that a path had been opened that joins the dismantled railway a short way E. This passes over the old Rhayader tunnel which has an information board showing the bats recorded there. The path leads back to the road in Rhayader.
