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

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 Lots of good paths and tracks to summit, although felling and replanting means even current OS map is out of date.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

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

Forest tracks from main road to trig; tried to find other Craig y Llyn (CT Mid Glamorgan) first.Aye Jimmy04/09/2010
Rain cleared as we started walking. Trig is fairly boring, but the escarpment to the north gives a view of the entire Brecon Beacons. Pretty stunning.huwthomas10/07/2010
From car at 923028 (13:00) near top of pass, followed LDP across boggy ground to edge of forest and along top of scarp till track led S to trig pt in clearing. Back more or less by same route; finish 14:15. dbb27/03/2010
With Pat & 2 dogs. Forest closed due to Rally of GB, but parked at Forest access Rd, walked NW on path round boundary then in. Trig, painted with "hand" sign, surrounded by portable lights and tape for rally. 40 min stroll.martin & storm21/10/2009

Detour from Beacons Way to gain this county top. A bit of a detour but the mass of the hill dominates southern part of Brecon Beacons National Park. Trig point disappointing but ridge walk to and from good views north.peter23/06/2009
Trig point, Route: Pontwalby - Cwm Gwrelych - Opencast - Llyn Fach - Craig Y Llyn. Path on OS no longer exists across opencast, very difficult terrain until Llyn Fach. Not recommended.Chris Williams22/02/2009
From the east and main parking area.Dusty29/01/2009
From E. Most of forest gone so good views. Still cutting. Tracks on map bear little resemblance to ground. Trig in a wide dead end track.destaylor21/10/2008

Parked at SN 923030. Scenery looks better on map than on the ground! White trig (S2045)and small mast but no views 'cos of trees. Not only is it highest point in W. Glamorgan, a little to E on faint track is highest point in Mid Glamorgan too!signyred18/07/2006

Stupidly wet day - we nearly drowned! If you're coming up from the nearest point on the A4061 as we did, it's easiest to use the cycle trail through the woods. The long distance trail slightly further north runs through a very boggy field.wheresthepath02/10/2004
