Using the diagonal path from SH91287703.summitsup14/04/2019
With Dad. 1000th Hump.ianwatson14/10/2018
Walked up from outside Gwrych Castle - I was glad to get to the top. Very windy by the pillar. I walked back down a different way.Alancache25/04/2018
From New Road up drive and past house. Kept to zig zag path and, although they are large zigs and zags, it got me up there easily enough. Nice views.clivevilla28/03/2018
Parked w Jenx off to SW on village green of Rhyd-y-Foel. Found path into woods w concrete steps nr main road, easy from there. Near top of diagonal line possible to cut more directly to top avoiding gorse scrubnordicstar22/03/2018
Up from New Road (plenty of parking). Immediately after starting up the driveway to a house went up a steep zig-zag path on the left. A nice top. Tried to go down the access land on the NW side of the fence and wall going from the top to Rhyd-y-foel but had to turn back as I couldn't get through the woodland.Alan Moore26/01/2018
Fron Rhyd y Foel up through wood. Excellent views. With RW.JohnIvor13/01/2018
Parked at end of New Road, used route suggested by andrew brown. Zig-zags a bit complicated, passed an ogof, steeply up. Short tough non-prickly vegetation helpful - what is it? Then along shoulder to top.Aye Jimmy31/12/2017
A quick bag from suburbia (Terfyn) footpath zigs and zags up edge of old quarry through Pines / Yew / Juniper / wild cotoneaster? Followed wall / edge of forestry to summit and trig. Fine views.briandavies24/12/2017
Parked on new road. Excellent views form the summitAlunrees3317/10/2017
Not well signposted but followed a track to the summit, great views of the coast and Snowdonia.Sihuws17/09/2017
P Llys Awel. First up Cefn yr Ogof then down the road to Pen-y-c-m.chrisbien10/06/2017
Tried to get up track from S, but gave up due to brambly overgrown southern end of path. Had a second more successful go from Terfyn.PeteF30/04/2017
From sea level, through middle gates and head up steep path, heading east passing tower. noone seems to do it this way.. struggled a bit, getting very unfit. carneddau invisible! Way back above Gwrych Castle.. its going to cost a fortune to get it repaired..mattcymru13/02/2017
Straightforward walk up from rhyd y Foel followed track from bottom of village green. Clear views on a sunny spring like day although a bit cooler on the top. Short diversion through the woods to the tower on the way back.Walker Dan20/01/2017
Small bagging day in the rain after the previous days exertions 4/9 (Cefn Ddu/Moel Tryfan/Mynydd y Cwm/Cefn yr Ogof/Moelfree Isaf/Moel Fodiar/Moel Tywysog/Mynydd Tryfan/Pen-y-Coed)Fergalh16/10/2016
Keep to paths! Leave any attempted shortcut to the rabbits and the gorse!jrj13/10/2016
From Rhyd-y-foel. You need to take the paths from the N side of the triangle. Concrete blocks, presumably to deter trail bikes (good!)- the paths lead straight onto access land, interesting scrub and limestone grassland higher up. No signage but well used paths, good info about hill in Valentine (pub- also well worth a visit) in Llanddulas.pwheeler12/09/2016
Bagged as YSM372 Cefn-Yr-Ogof T2.5 D3. The Hill bagging website said 'Park on wide streets of housing estate at 913778. A tarmac road leads up diagonally to a house and a narrow gate and path to the left continues up through the wood with 2 zig zags and to the top.' So we tried the hoose nearest the top of the hill but he was reluctant to let us park and we'd probably have had to walk through his garden to get into the wood. However after some sweet talking from Mr U2 he let us know about a secret path between two boulders down at 'the green' which went up the hill and along to the trig. So we took this (N53° 16.747' W3° 37.918'). Took a man path in one section which was very steep but direct otherwise relatively painless.thejackrustles03/08/2016
With K. Magical area that really deserves it's SSSI status; much botanical excitement. Worth exploring for a while. Many routes with no access problems. Area is obviously well loved.Ashley12/07/2016
From path through wood by Terfyn. Very difficult to locate as there are lots of paths but only a few to the summit. Only suitable in dry weather (lots of scree). Worth it for the extensive views.JamesD197210/05/2016
As arranc but scrambled up through the crags and steep paths - wonderful!Chris Peart09/03/2016
204m - Lovely day in winter, also saw the lookout tower.Rob-Nia23/02/2016
Got this one totally wrong. Walked up wrong hill and had to go miles further than expected finding my way onto the right hill- no easy route onto summit from south but worth all the effort in the end.Mark Sims24/08/2015
freshly painted trigAdrian19/04/2015
Parked at rhyd y Foel ad followed track from bottom of village greenThearlaichdubh22/03/2015
trip up with alex c to paint trig point again. very cold!mattcymru22/01/2015
Latest ascent of many.. Trig paint has been almost completely worn away by weather. Snowdonia hiding today. Highly dangerous wet descent via old steps and cavesmattcymru17/12/2014
Parked on new road. Went to the caves and through the woods past the ruins of Gwyrch castle then up to the summit on return. Excellent views for modest height. Only regret was not going up to the watch tower!!AlunRees3113/02/2014
En route to Elin's Tower.mad max14/06/2013
Park on wide streets of housing estate at 913778. A tarmac road leads up diagonally to a house and a narrow gate and path to the left continues up through the wood with 2 zig zags and to the top.arranc29/05/2013
With Bill and Andy. Parked in residential street to west. Steeply up past the cliffs. Lovely hill but pity about the litter. Descended through the plantations outwith the Access Land visited the ruins of Castel Gwrych on return these are incredible and well worth a visit. Scrambled up to the large cave in the cliffs but descent almost terminal on the wet limestone.mick16/05/2013
With Mick and AndyBillyP16/05/2013
Parked on residential road at SH 91232 77802. Then route described by Des Taylor team. (It's steep!) Well done on your completion Des.David Gradwell07/04/2013
Bagged with a group to celebrate Des Taylor's completion of the English and Welsh HuMPs.Alan Caine24/11/2012
Last E&W HuMP. Excellent company and good weather. Easy parking in New Road. A fine route provided by Alec Cameron. Up the track for several metres and then straight up a fairly steep path. He took us to the Folly then the summit. Cake and a a few bubbles. Then to the pub. Excellent day - thanks to all. No mention of DL P30.destaylor24/11/2012
From Terfyn (plenty of parking on road), with detour to tower for view. Des Taylor's E&W HuMP completion. A fine hill. Prominence now likely to be 102m, as trig is lower than summit.marktrengove24/11/2012
Via track that starts around SH 91310 77810 to the tower in the wood then the trig with the help of "trigging on an island" our local guide for Des Taylor's Welsh HuMP completion. He still has to go back to rebag the real top of The Verne in the prison.Dugswell224/11/2012
With the completion party. We seemed to scare off a few locals taking their morning constitutional. Although not access land, the adjacent & pleasant woodland to NE seems to be owned by a visitor friendly trust.Smudge24/11/2012
Same as Dugswell except the bit about afternoon s unshine as it was dusk and drizzly. But, hey, once again I have completed the Welsh HuMPs. And I have often thought about bagging this hill as I have driven past.Martin R31/10/2012
As Andrew Brown, super little hill with fine views in afternoon sunshine.Dugswell217/09/2012
Parked in park road just off rhyd y foel road to the N.W. As soon as you go up the track/drive to the houses there is a footpath immediately left. Take this steeply up and it goes right to the top. Cracking little hill.DARRENG09/09/2012
Parked on street - Ffordd Newydd - by junction, GR SH91267 77803 Up driveway to house and took second path on left, followed pathe up right hand side of disused quarry ( would be quite slippy in wet conditions ) to reach grassy path by wall continued following path to fence at Eastern corner of wood, easy hop over fence to top.Anton21/08/2012
Parked at SH9126577795 and followed driveway up to private house. Footpath follows side of houses into wood and zig zags up hill. Stay on paths as elsewhere is overgrown. House owner very helpful.andrew brown22/07/2012
It is a lovely hill - if only it was accessible. Given Gordon's GOML, I parked in Rhyd y Foel but could not get through the vegetation onto the hill. Reverted to Gordon's parking spot but found fields full of tents and horses so forced my way into the access land where it touches the Henblas track (SH91987702). Two BW fences!chriswatson07/06/2012
Superb little hill covered in rock roses - now promoted to Hump: Parked at SH91975 76830 and went up in crutches (25 days after fitting replacement hip) through 3x gates from SH91947 76917. Accosted by vociferous but fairly harmless lady GOML at gate on way down claiming it was private SSI and not access land: but in for a shock !GordonAdshead27/05/2012

Visited for the trig pre-HuMP days. Have returned four other times since, also including Des Taylor's completion day.Alex C04/05/2011
limest, lovely hill & view, 'BSM' trig 3550. from road to SE via Henblas tk RHW07/12/2002
Nearest hill to me. Done many times, mostly on my own. Never see anyone at the top. The views are very impressive though. The quarry spoils it a bit though. Always go up from Gwrych Castle.mattcymru03/03/1994
