Big wind farm development here on cycle way to S - best to approach from layby which has pretty much the same view as from the summit.twg2730/11/2017
1/5M From top of the pass wet path then good track to the top, wet and windy day.robertphillips11/11/2017

Continuation on from the Rhondda Cynon Taff summit, lots of incredibly bright green moss about! Maisie's 200th English / Welsh summit.DanMaisieBex14/10/2017
From viewpoint car park at SN927031. Path follows road, and then skirts top of cliffs (wet in places), and joins a stony track through the wood. At the second stone way mark head into the woods to find the most unimpressive 600m 'peak' in Wales (trig point is behind a tree, on the edge of a clearing). Views from the edge of the forest are good, but much the same as from the car park.jim.r28/09/2017
Standard route from the layby in rather damp, claggy weather. Very odd summit for a Simm - quite flat topped, surrounded by conifers and what looks like a small car park. Returned via the Rhonda top. With M and X.Herbert Anchovy04/09/2017
There and back from the lay by on the A4061 Hirwaun to Treherbert road, around an hour for the walk and theres a snack van still working in the lay by.WAYNE ROWLETT18/08/2017
With: hb; Walked from carpark on mountain road at SN927031. The path along edge is badly eroded by trail bikes. Trigpoint by open space amongst trees.Ian Baines28/08/2016
Craig y Llyn from SN 92689 03092ronaldo33304/06/2016
From the picnic site on the A4061. The construction of 63 wind turbines has taken over the cycle route to the top. The top itself appears to be in a security compound complete with automated scary message. The trig point is just outside. Glad we did it on a Sunday, probably very busy in the week.Newton Maximus08/05/2016
Started from viewing point layby on A4061 (SN92657 03094) following Coed Morgannwg Way east turning south at marker stone near Carn Fach. Trig and summit approx 100m on west side of track, but almost totally obscured from track by temporary works depot. Back tracked to fire break before marker stone and returned to layby picking up bonus bag of Rhondda Cynon Taff (C), Craig y Llyn (boundary)on way back to laybySteveSmith12/04/2016

First top on a Marilyn bagging day- straightforward route from top of pass car park via trackCas-gwent15/03/2016
From A4061 at 923027 followed national cycle route 47 west, which is currently a wind farm construction road, no fun at all. After the trig pillar, which has no views, returned on the Sky line path that runs parallel along the escarpment and has marvelous views. Don't cross the bog on the right of way back to the parking area, but continue to the bend in the main road, which is much drier.mindlessflogger13/03/2016
Will pick a better route next time - got knee deep in a bog.mike.hartley18/02/2016
Straightforward from the top of the pass.But the track marked with diamonds from the road is hardly visible and extremely wet through the bog. The footpath is the better option.jenx18/11/2015
With Jenx. Parked at the 923027 by the celebrated No Parking sign. The FP though across the moor is dreadfully overgrown and wetted out. Better to walk up the road to the trail at 922029and follow this to beginning of track at 916031. Followed all way to the right angle into forest and trig behind young spruce.nordicstar18/11/2015

Walked up from car park on A4061, a bit soggy at the start then a straightforward stroll up and along the path (great views to the North) before left turn into the clearing where the trig point was hiding behind a tree.mapple01/09/2015
Parked at car park on A4061 with easy walk to summit. Lots of construction work being undertaken for wind turbines.Ramblingpaul28/07/2015
from Maesteg with Mynydd Caerau, Mynydd Llangeinwr, Twyn Crugafon, Boundary, Mynydd Pen y cae, Moel y Hyrddod, Cefn mawr trig through Afan Argoed back to Maesteg, lots of turbine construction lorries on forest tracksunderhill26/06/2015
Would have been nice to have seen views. All cloudy. Forest path diverted. Trig point behind a �treeadriane20/06/2015
Spur of the moment decision to take in Craig y Llyn on the return from St Davids. Good decision. The car park on A4061 currently not in use, but we could still park on some waste ground further down. Easy walk to the summit where there are some wind turbines being constructed. Great views to the north.callumorr27/05/2015
Parked next to the No Parking sign one entry up and walked out and back on main track. Plenty signs saying no entry to unauthorised personnel and just as many indicating you are allowed to be there! Looks like 30 plus turbines being built.SS15/03/2015
Straightforward walk from the viewpoint. Area to west a building site as another wind farm starts to go in.MikeM27/02/2015
SOTA walk - operated ham radio from summit. Started out from wind farm access gate at SN 923027.G4OBK (Phil)21/01/2015

County top no. 59. By car from holiday cottage in Brecon to lay-by on A4061. Short out and back walk from lay-by to trig point on Craig y Llyn.Distance 3.4 miles; time 1:37; climb 604 feet. A warm sunny afternoon although with haze spoiling the views (temp 20 deg C).alan.65to7021/09/2014

Large parking area at 927031 W. on path alongside road for 400m and then continued W. along track to forest Forest tracks to trig pillar. (PM)gerrybowes10/03/2014
Craig y llyn, Boundary and Hirwaun Common from main road layby.rhalstead11/01/2014
Originally intended to do Chwarel y fan, but when I got tot the top of Gospel Pass I was in low cloud so consulted the list to see the nearest County top hopefully lower than the cloud base on the day. Glamorgan looked favourite. Parked in viewpoint lay-by on the A4061, easy path to the West above Llyn Fawr resevoir, a little deviation to the South before continuing West on a forestry track. Eventually track borders forest to the south, shortly a track branches off to the South, trig point soon visible at another path junction no views from top surrounded by trees.Malbow12/10/2013
A short walk on a rainy day from the layby at the top of the escarpment with Keith and Cai.islamidget08/09/2013

Plenty of parking options to east along A4061. We parked at entrance to the new wind farm site at SN921025. Kind chap at site security office let Jacqdaw use his loo. Lots of good paths and tracks to summit, although felling and replanting means even current OS map is out of date. Fantastic views to north of large number of major Beacon's peaks from viewpoint just north of trig.Hillsidenick26/07/2013
Hot walk up from Treherbert, via Iron Age village. Some clearance to the north has opened out wonderful views of Y Mynydd Du, Fforest Fawr and the Central Beacons. Trig point in clearing - Bronze Age cairns to north and south.thesweetcheat31/05/2013
13 mile walk from Cwmdare, bagging Mynydd Bwlfa trig then walking along edge to summit of Hirwaun Common, down to A4061, up to Craig-Y-Llyn summit, then walked back along Coed Morgannwg Way back to Cwmdare. The summit isn't quite what you would expect from such a good shaped hill.DanTrig31/05/2013
last of the snow. from burger-van-rhigos-viewing area.dicky06/04/2013
Start ~ Car park at 923026steve hudson18/02/2013
Parked at the viewpoint car park on the A4061 approx 2km to the east. Good views north during most of the walk.jonglew16/02/2013
Would be better on a clear, fine day with views toward the Beacons and over Hirwaun, etc.rypj8315/12/2012
From Toncaerau with Iain Brown. Followed way marked path to the last break in the trees with a feint trod.Eddie09/12/2012
Started from the viewpoint. Easy ascent.bowlesy10/11/2012
Pleasant walk up from the Picnic Site at the cliff edge. Quite a bit of snow on the North Side of the Forest. Good views to all the main ranges of the Brecon Beacons. Snow line was over 800metres by the looks of it on the main Beacons.isabelle05/11/2012
From the car park at the cliff edge, we followed the fence up. Family walk with the children (though 3 year-old sometimes wanted to be carried)AlexanderHoward11/08/2012
Didn't get the ascent quite right- parked 250 m N of pt482 (SN922025) near the summit of the A4061. In cloudy wet weather I hurried up the cycle route, a very good track used by trucks, so bailed out to a firebreak- soggy but direct. As the cloud lifted a bit I walked to the escarpment over which the views to glacial lakes were impressive.Here there was a good path near to the escarpment which I used to get back- much better than the way up.pwheeler25/04/2012
