Cefn Coch-Coety Mountain-Coety Mountain Boundary-Gwastad-Mynydd James-Mulfran from north. Couldn't say much about first 3 as visibility down to about 30m which made things interesting. Happily cleared for middle part of day.TK09/03/2024

With KeithByTheC. 12.8 mile circuit from Abertillary. Abertillary, Coety Mountain, Cefn Goch (Tump), Cwm Celyn, Mynydd Carn-y-cefn all the way along the ridge to entrance of wood at 203048, then down through wood to Abertillary.JulieB25/03/2022
From Coety Mountain. Mostly good tracks until very near summit where more tussocky, heathery ground has to be crossed. KeithByTheC25/03/2022
Circular walk from Blaenavon, fine weather, good walking on paths but off paths is very slow in heather and long grass. Lovely taste of the Welsh countryside.JazDisney16/01/2022

Solo Blaenavon loop on the hot Bank Holiday. Up from Forge Side to Mynydd Coety, then dropped down to the thankfully dry col. Up to the tussocky, heathery Cefn Coch summit, then dropped steeply down to Waun Afon. The causeway with crashed car was just about passable in relatively dry conditions, although it was a bit of a squelch! Up to Carreg Maen Taro standing stone then on to Pen Rhiw Ifor tip, Cefn y Galchen and the Carnedd y Defaid cairns before returning down to Blaenavon.thesweetcheat31/05/2021
Parked in Whistle Road car park. Tracks to old mine, then straight up to Coety Mountain. Onward to Gwastad and back to Cefn Coch. Direct return from Cefn Coch.PGCE30/03/2021

Then along rough off road vehicle track along west side of Coity Mountain and up to near summit of Gwastad. Short navigation through heather. Back track to due west of Coity Mtn summit, then short cross country to the top. Descent to mine road and back to Whistle Halt. (S)silveracorn_alan21/07/2020

Circular route from Cwmtillery taking in Gwastad, Coety Mountain (and boundary 'top') Cefn Coach and Mynydd James. Another disappointingly flat heathery top. Lovely sunny spring day, dry underfoot and skylarks above.milimana25/03/2017
From Blaina, circular walk inc. Mulfran and Mynydd James. Mixture of muddy quad bike tracks and off-piste over rough tussocky ground. Snowed quite hard at one point, but nothing settling.jonglew09/04/2016
Circular route from Cwmtillery. Useful car park at 21781 06091: Mynydd James, Mulfran, Cefn Coch, Coity Mountain & Gwastad. All round topped hills. Route via various quad tracks with a fair bit of yomping across heather thrown in.Cas-gwent02/02/2016
Coety Mountain, Gwastad, Mynydd James, Cefn Coch and Mulfran. Parked at the Whistle Inn - 12.93 miles. On my own and went pretty fast 3h 54m.clivevilla07/10/2015

From near the Whistle Inn with A. Glad ground was dry. Good viewsPeterD18/07/2015
Started at a carpark in Cwmtyleri. Followed Afon Tyleri but high above. Walked round head of valley an upto Cefn Coch. Wind, rain and cloud made the walk 'interesting'.MikeM28/03/2015
Along mine road to the end then up to the rather flat tussocky plateau where GPS found the summit. From there on along the ‘ridge’ to Cefn Coch before returning to take the excellent ROW back to the mine road.SS17/03/2015
4/8 This was the second part of major circuit of the 5 peaks on plateau....like all of the peaks here no trig pillar summit was a short journey to left from track around 400 metres or so.Fergalh13/12/2014
Starting from the bottom of the Cwmtillery resevoirs. We made our way up through the fields east of Cwmtillery and up onto Gwastad. We found that a lot of the rights of way shown on the map or nonexistent now. We did manage to find tracks most of the way along the ridge to take in Gwastad, Coity Mountain, Cefn Coch and Mynydd James. We had to fight across heather, tussock and blaeberry to reach the first three summits which was very tough walking. Trying to find our way back off Mynydd James was incredibly difficult. We ended up going very steeply downhill through 7ft bracken before eventually finding a path much further down. Wouldn't bother doing this again, but it was a fun day out. With Keith.islamidget09/08/2014
As for Coity Mountain. Summit on this one not overly clear either.isabelle29/12/2013
With Val From Whistle. Tussocky unclear summitmike.hoult02/12/2013
Springy heather, no paths, doesn't matter. Lots to do in Blaenavon and walk to Myn James via Cefn Coch and deep valley 218 089 makes good day.dicky19/05/2013
Very boggy walk approaching from Big Pit. Featureless summit, but great being the only person up there.Tracey11/03/2012
Walk from the Big Pit Museum, doing a round of Cefn Coch, Coity Mountain and Gwastad. Lots of yomping accross open moor, didn't see another soul all day.rhalstead24/01/2010

lovely valley altho hills a little ordinary. cwm tyleri, track junction by forest @ 223078 RHW16/05/1998
Took in this Dewey as on the route of a big linear 30K+ day run on a very hot day with Rob Small between our two distant cars linking 4 marilyns N to S above the Valleys. Flagging well before the end in the heat, but enjoying the unusual contrasting mix of urban/ rural landscape; even the strongly smelling brown source factory near the end!Chris Pearson05/07/1997
