With E. Parked on forestry road at foot of hill opposite minor road junction. Walked up road (surprisingly busy) than onto grass and flat summit. Went to both SN6647009482 and SN6650109537 to ensure highest points covered. Also had a wander around the nearby ancient earthworks marked as Penlle'r Castell on OS map which are slightly higher but man made. Good views on a sunny afternoon. Area surrounded by wind turbines.Beeliner16/07/2019
Final county top of the weekend with Pete and Joe, parked up as close as possible on road and walked over, wandered to hill fort too.penbet16/06/2019
Quick visit to summit and ancient earthworks from road to the west.Winterfloodian30/04/2019
GPS coordinates downloaded in 2016 clearly wrong, checked and found they had been corrected in 2017. Not quite a roadside bag, it takes a minute or two to walk from the road HP across rough heather to the summit.Topographer5729/09/2018

I thought this was going to be exciting when I saw the signpost to Mynydd y Betws on the A474. Must be a top tourist attraction that it deserves a signpost? Sadly, not.Gill22/02/2018

5/8M another drive up got out wandered about.robertphillips10/11/2017
We drove to the top on our way from Mynydd Uchaf to the beach. I got out of the car and walked around a bit to make sure I got it. With Keith and Ross (although Ross didn't get out of the car).islamidget19/06/2017
Drove past point on road. Stopped in layby to have picnic and look back at point.Hippy7713/02/2017
Drove up did a 10 point turn. Got out with my daughter Isabelle we wandered to the point 374 hard to distinguish. Visited castle and drove back down. Not the best and the wind farm makes it worse.isabelle07/08/2016
Short distance from road to HP, between heavy showers.PeterD03/08/2016
Not far to walk to this one in the mist.Neolith09/07/2016
Drive-thru Marylin on minor roads - walked to castle remains and back. Decent views amongst wind farm.twg2727/06/2016
No walking involved although I needed the GPS to tell me which side of the road I should stand on.Newton Maximus20/05/2016
Drive on summit. Wandered the few metres to the actual summit. Horrid weather, not much better summit. Ho hum.geralddavison01/05/2016
From Warwick in 3 h.... by car. Walked from layby to tumulus and back, crossing the highest ground.pwheeler26/04/2016
A drive thru Marilyn, though I did park up to walk the few yards to the very top!Cas-gwent15/03/2016
Parked on east side of road near 371m spot height, SN 66416 09393. Just a drive past bag. Got out of van walking towards high ground to the east and ended up at castle with high ground behind me. Headed back and plumped for spot at SN 66461 09465. Easy bag, 0.29 miles walked with 5.45m of ascentSteveSmith15/01/2016
Given the ickiness of the weather im a tad suprised i made it up here even in the car Roads like rivers in places. Top is instantly forgettable on a day like this with no views. Why am i here?stig_nest14/11/2015
With Chrismagirob13/10/2015
Unashamedly parked at the road highpoint and had a little wander around the grassy, tussocky top which must have looked odd to the passers by... Didn't bother with castle as was pressed for time. Not the best.bowlesy10/10/2015
Appears to be a tuft of grass very close to the road where we parked. With GB.bolton28/07/2015
Parked on minor road to west at SN664094 A short walk to the summit which appears to be at or close to a large clump of moorland grass. (PM)gerrybowes28/07/2015
4th of 5 today. Parked on road near summit and short walk to top. Walked on to look at hill fort. Very interesting, which is more than can be said for the summit! On my ownmike.hoult18/05/2015
Followed rough grass path from track/road junction.rhalstead05/04/2015

4/4 easy top to bag short walk from car. nice views on awful dayFergalh15/01/2015
Dash to top from car after work. Not a great spot to stop in the fog...MattM29/10/2014
Car to nearly top...dicky31/05/2014
A very easy peak, on a stunning day. Could just about make out Pen y Fan to the east.huwthomas18/04/2014
Plenty of parking here. Walked over the trig first then headed S to Penlle'r Castell and hill top - broad flat top with nothing to mark it so couldn't say exactly where it was. Could hear wind turbines (not marked on my 1:25k), but see nothing. Then they suddenly loomed out of the mist - surreal!jonglew25/01/2014
Parked on grass verge (limited spaces) at high point on road to west and walked to castle. Being a bit lazy as lots of hills to fit in today. Good views, but spoilt (in my opinion) by the wind turbinesHillsidenick26/07/2013
Short distance from road junction. Old fort worth a lookshirley pbgv17/05/2012
A bit misty so no views. Finding the route up from Betws was harder than it looked. The plaque says the "hill forty" is medieval not Iron Age.clivevilla16/11/2011
Windy, mild, pouring, misty, no views.iangalbraith09/10/2011
Walked up from ammanford railway station and made a enjoyable days walking. The summit is a broad flat plateau with the summit reading on a grassy path. Carried along the path to Penlle'r castell which is definely worth a look,it has a plaque inside.hodder28/04/2011
Another from the road in mist. Dodgy considering the traffic.Eddie25/02/2011
Probably one of the few to walk from Ammanford!Buteobuteo31/07/2010
Drove from Ammanford up mountain road in gathering darkness. Summit unmarked; appeared to be grassy mound close to road. dbb27/03/2010
just off the road, nice views as the sun just about setting.asbown01/03/2010
With: hb sb; Parked on minor road and walked the short distance to the top. Sort of just stepping out of the car!Ian Baines24/07/2009

Short stroll from car and choose your top.Aye Jimmy03/05/2009
As Des Taylor states, a stroll and well worth the extra 100m to the Iron Age Fort. Lovely views on dry, clear sunny morning.Dugswell222/03/2009
Stroll. Worth the extra 100m to the iron Age Fort.destaylor08/09/2008
A short dash and grab in the mist. No view. Could only just about make out the car 30 meters away.Father Ted26/08/2008
As this hill is close to home I have walked to it from all directions over the years. Now in the middle of wind turbines. This was the occasion I logged the triangulation pillar. The hill fort at the summit is worth the short walk.Dusty08/10/2007
