From the farm on the corner at Baglan. Towards the trig a faint path enters through gorse into high bracken but no trouble at thus time of year. High Point a little along from the trig in light woodland.NormanW08/10/2019

Run from Neath along Bwlch Road and picked up Wales Coast Path upto trig point TP4379. Perfectly clear day and cracking view of Swansea Bay and across the channel to north Devon coastline.philwhit11/05/2019

From Blaen Baglan. On summit at last after several false trails. Tracks a/c up around hill as far as eight o'clock then sharp left back to nine o'clock. From there a narrow path leads eastwards to the trig. Soldiered on to given HP but amid the long heather, bracken, brambles, shrub and young pines I cannot imagine how anyone located it with any certainty.Topographer5730/09/2018

4th and final Marilyn of the afternoon mopping up in 32C. From N, parked at farm Blaen-Baglan. Followed tracks all the way, then path through gorse to trig.Minto10/04/2018
A train walk, starting from Port Talbot Parkway and finishing at Skewen. Up the Wales Coast Path to Mynydd Dinas, which is not as expected from the map: it's a lovely heathery summit with a few pine trees. Down the WCP to Blaen-Baglan, then along the road to pick up the by-way and path leading to Foel Fynyddau. Back to the road, and towards Neath, picking up the forest track after 280m, which comes out above a hill fort, then down to Pant-Howel-Ddu. Down the very quiet and pleasant road to Neath, and a soggy by-way to Pencaeru, and into Neath. Over the pedestrian bridge past the station, and up the hill towards Glynfelin. Paths and tracks up the hill to join the bridleway below the summit of Mynydd Drumau. Over the fence to the trig, then soggy, muddy grass to pick up the bridleway into Skewen, for the return train to Cardiff.Gill18/01/2018

From SS759925. Made at least three forays into the veg to make sure of the extra 22cms but can't be sure if I located the bit of reference rock as it would seem to now be well covered. Anyway, I'm counting it as I must have trod on everything in the direction and distance given from the TP.summitsup06/12/2017

From Blaen Baglan on forest track past 'Oscars view' which would have had a fine view over Baglan Bay chemical works when it existed. Found small track to trig and fought way to HP.PeterD15/08/2017
From Blaen Baglan where there is space for a few cars. The Wales Coastal Path is well maintained and easy to follow as are the forest tracks. We found the small path to the trig without too much trouble. However, the RoWs to the south and east of the hill are a total mess. Loads of blockages, undergrowth, overgrowth, fallen trees, aggressive dogs and subsiding paths. Stick to the forest! With Keith and baby Ross.islamidget19/05/2017

Pleasant solo lunch spot on route home from Pembrokeshire. Went 65m east of trig to ensure I had high point. Second ascent. Approached from Baglan in North and on paths all the way, initially waymarked Welsh Coastal path then small obvious footpath to trig. Lovely views across to the coast.sunshine.Denise 23/09/2016
From Cwmavon. A nightmare of disappearing and blocked paths, bracken, brambles and gorse. Eventually used PROW through Nant-y-clais despite unwelcoming signs and farm dog. Easy once onto the forestry tracks, with just a bit more gorse and shrubs to make the search for the summit tricky.welshyboyo16/08/2016

Parked in outskirts of Baglan to N of summit where path meets road (plenty of space), and took an easy walk to the top. Lovely views of Port Talbot, which actually looked attractive in the spring sunshine.Cas-gwent26/04/2016

Hard to believe trig is not the high point. But walked east towards point marked by hill-bagging, pleased I did as identified by survey as being .22m higher than trig. Now overgrown with deciduous shrubs and saplings. Parked in Smallwood Road and headed for Wales Coast Path via tortuous route from Pant-yr-Arian Lane. Smashing views all round, most poignant of all to the south over Port Talbot Steelworks currently under threat of closure. Here's hoping it can be saved for the sake of the area and the country.SteveSmith12/04/2016

After camping at the Mountain Center at Bryn Bettws lodge, parked on the SW fringes of Cwmafan 776918. Walked NW on a drive and Right of way on the west side of a stream, which degenerated into a trash through the wood. Then went west at a farm to forest tracks which spiral up to the nice top. Great views of the works of man. Continued on the coastal path down to a path that contours the east side of the hill and joins the road at a cemetery. A good walk but best done on a Sunday morning when the traffic noise will be at its lowest.mindlessflogger12/03/2016
From Baglan. A nice stroll anticlockwise round the hill. Approached the top from the SE, but found the shorter route back from the trig to the NW.jenx18/11/2015
With Jenx, from farm parking nr Baglan, lots of space. Welsh coastal path to near high point at gate, take track to left about 50m short of this and look for track leading off direct to trig. Local's party rubbish strewn around, good views.nordicstar18/11/2015
Parked at blaen baglan. Loads of room. First of 5 marilyns today.. just about the most enjoyable. Which doesnt say much for the others. Wet wild and with virtually no view. I found the trig easy enough but after a 5rample around in pouring rain i didnt bother spending more than a couple of mins looking for the exact top. My knees were higher than it -so given the conditions that'll do me.stig_nest14/11/2015
