Marilyn 4 of 4 on a wet day with no views. Parked at 044884 and walked to the trig first then on to the festureless high point. Nice chat with the lady at the gate of Langton Farm walking her alsatian.NormanW07/10/2019
1/2 Parked on road corner and followed track up to Langton Court Farm and then footpaths/through fileds to the top, good views, lots of sheeppenbet26/07/2019
Mynydd y Glyn from Trehafod station, Cefn Eglwysilan from Treforest station, and Garth Hill and Craig yr Allt from Taffs Well station, all on the same day.Mark Jackson26/10/2018
From road bend south of Langton Court, up past the farm and into the fields. Like so many right of way paths in England and Wales, this one ends with a barbed fence where according to the map it should continue with a marked stile.Topographer5701/10/2018
From SE, as others. FP seemed to off piste, but route ahead was obvious. Large pole lodged in Trig point which I doubt will survive a healthy breeze. Also went to HP but concur that trig looked higher. Good view all round and across the Bristol Channel.PeterD05/08/2018
Trig point definitely looks higher!elizyanne15/07/2018
From bend in road to SE, as many. Parked at start of track to Cefn-Coed, walked past Langton Court, fp then direct to gate and trig point. This far, a Vale of Glamorgan hill but from the HP the view is classic right into the Rhondda. Pleasant 75 mins return walk from this side, glad I didn't try and do it from public transport as I thought I would. You do get a view of another trailbike trashed area above the forest but all was quiet on this sunny Friday afternoon.pwheeler20/04/2018
From SE. Parked at start of track to Cefn-Coed and Langton Court farms. More horsey places - gone hill-walking to escape the beasts! Up track and across fields to Trig and summit (further on!)Minto10/04/2018
Third hill of a train bagging day, after Garth Hill and Craig yr Allt (from Taff's Well station). Onto the train to Trehafod, then up various bits of road and steps to join the bridleway heading steeply through the forestry. The BW is a bit wrecked at first, thanks to the attention of motorbikers, but it improves higher up. Across the first forest road, then right along the second road to exit the forest. The sun in my eyes made me think that the remediated slag heap was a nasty bog, so I followed the road to where it hits the forest fence. Through a hole, then various tracks around the side of the slag heap, through a gate and onto the hill. Not as boggy as it looks, then easy grass to the trig. Strolled along to pt 377, from which the trig looks much higher. Back easily across the slag heap, and down through the forest. The return train turned up 2 minutes after I arrived back at the station.Gill19/01/2018
8/8M last of the day parked bend in road track past farm then through fields to trig and summit further on.robertphillips09/11/2017
Started at Barry Sidings Country Park, walked up through the forest, lots of unmarked paths and extra trees since our map was made so it was a bit of a navigational challenge but figured if we kept heading uphill we were on track! Eventually worked out exactly where we were, left the forest and crossed the field to bag the trig point and the high point. Really lovely walk on a beautiful sunny dayWackywelshy23/09/2017
With: hb; From sharp corner in road, met owners of Cefn Coed on horseback. Walked past this then Langton Court FM then followed track for 300m before striking off direct to trigpoint. Went past this to real top then returned back over Trig again and down to car.Ian Baines19/08/2017

With TJB. Used FP past Cefn-Coed farmtrimarc227/07/2017
As others have, we parked at the end of the entrance to Cefn Coed farm. We followed the lane and then RoWs some of which are blocked, but there are easy diversions. Went to the trig, then the summit. Beautiful day with extensive views. With Keith and baby Ross.islamidget08/05/2017
Parked at bend in lane near Cefn Coed farm. Spoke with lady on horse about potential wind farm development planned. Lets hope not Track leads to open fields though dubious line as this seems to be barb wired. At the point where the fp goes diagonally across the fields I headed for the obvious top. Passwd by the trig point and over to unmarked grassy summit. Young lad with dog talking to someone on his phone seemed happy with the view too. Returned via trigpoint. Blister developed which cut my weekend short (but not before popping out to Pembs county top.)stig_nest16/09/2016
From Langton Court Farm. Good views from top.twg2701/07/2016
From E end of Trebanog estate. Plentiful parking. Followed tracks NNE for 1000m before taking summit beeline.jimbloomer28/05/2016
Fed up of driving, we parked on a wide verge under the pylons 048882. Walked up lanes to Langton Court farm 044889. Jumping gates we followed the typically blocked Welsh right of way to the final grassy summit lump. Fine views in the spring sunshine but had the feel of a forgotten unloved hill. Strange alien bleeping thing near the top!mindlessflogger11/03/2016
From Cymmer- a pleasant enough walk to top via the trig point.Cas-gwent07/03/2016
Pouring rain and mist again. From track up to Langton Court Farm.jenx19/11/2015
With Jenx as she says. Park at road end of lane, room for a car or two. Mindless flog up the hill in wind and rain. 1/7 today but was on verge of giving up! Trig point and then across the 'moor' to open fell top - no cairn just wet grass. Dull as they get.nordicstar19/11/2015
Parked on bend below Langton Court Farm. Followed track to summitRamblingpaul25/10/2015
Parked at end of private road at ST 043883. A 27 minute walk to the top for a SOTA session on VHF.G4OBK (Phil)14/08/2015
Ample parking on the bend at 044884. A surprisingly easy walk of 55 minutes via Langton court with GB.bolton14/07/2015

With Iain Brown from Langton Court Fram where a builder questioned our sanity. We nearly prooved his point by going over from the trig only wg=hen we realised the highest point. I really must cease chattering!Eddie10/07/2013
From Cymmer. Up the track which begins at the roadside just beyond Hillcrest Drive. Took in trig first, quite a few people on scramblers near the top.bowlesy09/06/2013

Parked in the estate to the west to visit summit and trig on sunny afternoon.Dugswell230/06/2011
Much easier than anticipated; much of the hill is beautifully cropped short turf and is superb walking country. I made the top from Porth railway station in just 45 minutes.johnabutler220/10/2010
From nr Heritage Centre in Porth. Various trail bike tracks up old tips until upper fields reached. Trig first then further summit.Aye Jimmy04/09/2010
Up from the road, past Langton Court Farm. Nice views all round. Can't believe the spot height the the NW is higher than the trig, but went there anyway!huwthomas27/02/2010
