Second of three Deweys from the free car park at the start of the road leading to the Whistle Inn 23004 10312. Ten mile done in four hours, route was Cefn Coch, Coity Mountain and Gwastad.WAYNE ROWLETT19/01/2020
Struggling to find anything good to say about this hill. However in the 50 minutes it took me , my wife really enjoyed her visit Underground at the Big Pit.NormanW06/10/2019

From NE. Looked for path along RoW from south corner of Big Pit compound but found only long grass. Animal tracks up shorter grass higher up but featureless summit is defended by tussocks on all sides.Topographer5704/09/2019
With E. Parked at Big Pit Mining Museum. There is a small area on access road marked for walkers as Museum car parks close at 17:30 with locked barriers. Walked around S side of museum buildings along access road then footpath onto open land. Once past path and stile beside museum, waist high in bracken up to access track from largest of the old quarries along hillside. Impossible to locate track up hillside nor smaller path further N. Hillside covered in man (and woman) eating bracken. Continued along access track N until reached track crossroads running N - S. Turned S up steeply rising track above quarry until ground levels out just before lone wind turbine. Then a slog over tussocky grass to summit which is a grassy rise clearly visible from surrounding terrain. Continued N to bag Coety Mountain Boundary another 200 metres further on. No feature only more tussocky grass. Rather than retrace steps, continued N to unmarked path which meandered down to Forge Side.Beeliner14/07/2019
1/7 Parked on lane to east, first county top of the day walking through slightly damp tussocks, mostly easy. Hill summed up by burnt out car on way up.penbet15/06/2019

2/3 - from CP at 2018109 - in fine weather - headed down track then onto ridge - windy from SWwychwood19/02/2019
Brilliant clear cold snowy day. Couldn't find the obvious paths marked on the OS 1:25k map, so spent some time traversing very boggy ground - lucky it was frozen!Speleoprez30/01/2019
Used Gill's route - as she says, a bit boggy lower down. Ponies were very friendly.SteveG10/01/2019
From Big Pit - wet windy low visibilityabbo000115/12/2018
From Big pit walkers CP which is further up the road on the left past the bus CP. ROW then up past the quarry and onto summit with elizyanne.GmacT16/07/2018
Finding the initial path through the tussocks was challenging and then used what would have been the tram line. Chatted to a biker that cycles everyday and wants to reach the top of the track in one go. Not today!Headed straight up the side of the quarry to the top.elizyanne16/07/2018
Coety Mountain, Coety Boundary Top and Gwastard ( careful how you say that one), with Scout from Big Pit car park; hard walking underfoot at times. Dry weather.Lou12/05/2018
From SO238089 - the walkers CP at Big Pit. Not the most inspired choice of ascent for hip replacement rehab. Also visited the nearby poss HP alternative to make sure.summitsup06/04/2018
A nice walk, once above the bogs. Choose a dry frosty day for this one. I parked at Forge Side; just follow the signs to FS, and you come to a surprising car park below some sheds, right by the start of the footpath up the hill. FP heads SE across pony fields, very wet near the feeders, then joins a bridleway heading W. Very wet in places, but the worst can be dodged easily. Improves to very good path by the ruin. When it crosses the high track which contours the hillside, just go straight up the hill, easy going until the summit plateau, which is a bit rough. The top is obvious, though best to wander along the hill top just to make sure of the bag.Gill23/02/2018
From Whistle Inn via wind farm. Very straightforward.lenman31/12/2017

4/5M From big pit cp up left hand side over couple stiles through reeds to better ground to the top.robertphillips11/11/2017
Followed Fp from the 'Big Pit' & then over open moor between the air shaft & disused level. HP quite obvious. Lots of caterpillars about.DanMaisieBex14/10/2017
From Big Pit parking spaces just outside car park reserved for walkers. On the down side, the stiles and footpaths are in terrible conditionmaknipe13/10/2017
Ascended from the Big Pit car park, very boggy in places but enjoyed the colour on top with all the heather in bloom. Got a great view of a Fox who was so engrossed with hunting that he didn't notice that I was only 15 feet away. Enjoyed some juicy bilberries and also walked to Trig Point S2193. Enjoyable couple of hours!Gerry the Ranger21/08/2017
With: hb; Parked just beyond Whistle Inn. Followed excellent path as far as new wind turbines, then track on SW side before cutting across to summit Heather mound and boundary top. Returned by same route. Very easy paths.Ian Baines20/08/2017

From the Big Pit museum in Blaenavon. No trace of a path on the ground after leaving the museum's fence. It was rough going but not the swamp that has been mentioned. Then a pleasant circuitous descent round Mynydd James to Blaina.Alan Moore16/06/2017
Circular route from Cwmtillery taking in Gwastad, Coety Mountain (and boundary 'top') Cefn Coach and Mynydd James. Slight heathery mound just about discernible as top, but no real path from main track to the W. Lovely sunny spring day, dry underfoot and skylarks above.milimana25/03/2017
From Big pit. Free parking can be found on adjacent wasteground. The footpath that heads to the upper track starts ok but then disappears into a swamp. The path clearly follows an incline however there is a drainage ditch which needs crossing first.. the walking pole put this at least a metre deep. Once on the incline its straightforward to the upper mines. What a mess when you get there. Beyond the compound a path leads up onto the open moor. From there its sheep tracks and then pathless to the top. Its suprisingly quiet and the distant views are decent.stig_nest15/09/2016
Circular route from Llanhilleth taking in Gwastad as well.liljonb29/08/2016
From Big Pit car park. Overcast, warm, calm and good views.iangalbraith06/07/2016

Walked up from and parked near a pub to the north.Neolith19/03/2016
From Big Pit, nr Forge side. There's a walkers CP signed that isn't pay and display for the Pit. The OS map is incorrect, in that the FP shown from South side of Pit area doesn't exist on teh ground. Instead walk West along the Northern fence and then head for the raised dyke area through the swamp heading to old disused mine. Up the north edge of this and across plateau are to the mound. Unexciting.nordicstar20/02/2016
We got a soaking which didn't help. Industrial history of the area could make it all more interesting.jenx20/02/2016
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
After Mulfran & Mynydd James. Found TP19304 Block and left it uncovered.Dusty30/08/2015
Near the mine. Got horribly wet. Boring flat toptallblond05/08/2015

Parked at 227098. An easy and pleasant climb to the summit with GB.bolton15/07/2015
Parked at side of wide track beyond the Whistle Inn at 228100 – South up track to boundary & then SE to summit & Torfaen UA Top. (PM)gerrybowes15/07/2015
Waited for the thunderstorm to pass! Then as per GB in ten days time.tim74705/07/2015
Continued on track from Cefn Goch. The boys and their bikes seem to spend a lot of time up here. Summit obvious, a low mound sticking up out of a flat top.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
From the Whistle Inn. On to Coety Mountain (boundary)Newton Maximus27/02/2015
Started at the Cumtillery duck pond, then up the valley south of the highest point. Wondered about trying to decide which was the highest clump of heather until Mrs Mindless flogger had had enough. (about 10mins). Returned via a track to the north but there where lots of motor bikes using the hill as race track. A nice day (snowy and clear) but a hill so uninteresting that no one can be bothered to build anything on the top, which makes it a bit different.mindlessflogger08/02/2015
SOTA walk - operated ham radio from summit. Started out from overflow car park above Pit Museum SO 240086.G4OBK (Phil)21/01/2015
5/8 This was the third part of major circuit of the 5 peaks on 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.
