Cycled up from the south side. Misty on the top and the din of wind turbines!brandybordeaux27/12/2019
From farm at 008806, parked there with permission. Easy tracks up to summit wind farm. Descended in twilight.Topographer5708/09/2019

From Chapel Car Park, SO0006780152, 4.5m circular, lovely weather and good views.Jephcote8319/04/2019
Windmill overload but still a very pleasant gradual walk up from Newtown.Alex C02/11/2018
From Y Foel. A steep climb up bracken to pt479 and the broad ridge, followed by the road to the top. Down to Cloesffynnon farm on nice farm track.Alan Moore10/10/2018
First of three Dewey’s from the entrance to a wood at 00557 77901 down the road from Glyndwr’s way, on a fourteen mile walk taking five hours. Route continued onto Crugyn Llywd and Brondre fawr hill.WAYNE ROWLETT25/08/2018
Parked at the Community Centre SO 001817 and went down the hill then up the hill via the ROW's up onto Graig then across to the cairn. Bagged the trig as well. Very Hot and steep. Returned same route with elizyanneGmacT19/07/2018
Oh the down before the long up is pretty but you know it will be an up on your return! It felt like a long slog probably because of the heat.elizyanne19/07/2018

A pleasant walk from Cloesffynnon farm, up the main track. The farmer very kindly offered me a parking place in the farmyard, and was very relaxed about the prospect of a trespass up the track. Great conversation with him when I got back, about sheep and wind farms.Gill15/02/2018
Parked at road end north of Cloesffynnon and walked to the highest point on the wind farm. Operated ham radio from summit for SOTA.G4OBK (Phil)12/01/2018
Easy parking on road corner by community centre to W. Up and down on good tracks.rhalstead29/05/2017
Drove along roads signposted Wind Farm to Bryn Dadlau then run to summit and back. Sunshine and cloud, light winds, views from Brecon Beacons to Cader Idris, as for the last 3 days. I took a map, but if you follow signs to high number L turbines, they take you to the summit which is obvious from over a mile away. Good surface on tracks all the way, some gates locked but easy to negotiate. Just over an hour made this hill surprisingly enjoyable but I think I would have got fed up with it if I'd done it at walking pace.pwheeler02/05/2017
Also parked at farm to SW there the sheep were in the midst of giving birth. Waled up to the windfarm along the footpaths and then along the plateau through the windfarm. It would have been fine except one of them needed oiling.Father Ted24/03/2017
with Alastair and Sarah. Asked permission at Cloesffynnon farm and parked at the end of the tarmac just to the side of the road. Easy ascent of the wind farm access track to trig point for SOTA activation in the fog.M0YDH17/12/2016
6/11 Sixth of eleven on sunny but cold day (Llechwedd Llwyd/Bryn Du/Bryn Mawr/Old Chappel Hill/Pant-Poeth Hill/Peginn Mawr/Graig Iar/Molefre/Pen-y-Ffynnon/Coed y Gaer/Bryn Gwyn)Fergalh05/11/2016
Parked at the windfarm HQ to the NE. Extremely still day, with low cloud. Atmospheric!huwthomas25/08/2016
#593 - 4th of the day. Parked at 00914 80906 and took track up to another windfarm.tim74709/06/2016
With Trefor. 4th Marilyn today. Caught in another heavy snow/hail shower, the story of today. Parked at fork in road above Felin Gythos. Followed wind farm access road to near summit. Great viewpoint and interesting to see the wind farm.mike.hoult29/04/2016
Easy ascent up wind farm track.Lionel Bidwell03/04/2016

Parked on side of road SO0032580387 followed farm tracks on right of ways until near summit which is large cairn with gnarled tree truck sticking out & a nearby trig point. Back at car had a chat with nice farmer who having seen maps was concerned more wind turbines were being planned. Spoils the scenery - he spoke with much wisdom.CodyleCoyote22/03/2016
Parked at 006805 and followed the track to the wind farm and trig point. Continued on and descended the bridleway back to road head, although this hasn't seen any use for a while. A pleasant evening stroll (assuming you don't get worked up about the wind farm) but recommended on a windless day, as the turbines are noisy.mindlessflogger19/06/2015
With: hb; Ascent from road end at SO009808 on access track to summit. Two Radio Hams were huddled around the summit in the persistant rain. We left them to it.Ian Baines12/03/2015

Final Marilyn of the tour w Jenx. Up the track from farm as described by others to the turbine cluster. Trig has a ghostly feel and is in the process of dis-assembling itself in the grim location, not helped by swirling mist and the turbine din. Bearings sound on the way out. Cairn still has the stump, like the hill in general.nordicstar14/12/2014
A steady climb from the west, making good use of the access track to the wind farm. (PM,CM)gerrybowes27/10/2014
Parked the car and headed east and up the track at dusk. With GB and CM.bolton27/10/2014
