1/3 - from CP at 2018109 - in fine weather - headed down track then onto ridge - windy from SWwychwood19/02/2019
From the cp at the start of the Whistle Inn road. Good fp to the ridge and then tussocks but not desperate.Campbell Singer01/04/2018
Parked on wide verge beyond the Whistle Inn at 228100 – S. up RoW to col & then NW across tussock grass & bilberry to arbitrary high point in heather. Descended ENE to track & then back down RoW to car. (S)gerrybowes25/09/2017
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
Last of 6 this morning. Very peaceful. Nobody about today.Dusty30/08/2015
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
From pub to NW.destaylor10/03/2009

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
