Logged Descriptions  (logged by 41 users)ByDate of Ascent
Parked by cattle grid at 855783 - Over gate & headed down to col, crossing a barbed wire fence on the way - From the col, a tussocky climb to the unmarked summit. Fairly easy to pick out trods between the tussocks of dead grass, so winter possibly best time of year to make an ascent. (PM)gerrybowes24/01/2018
A good idea to do this during winter as the grass is short. Could be a nightmare otherwise. From the cattle grid car park at 855783. With GB for this under 1 hour return.bolton24/01/2018
Dreadful man-eating grass between the forest and the summit.clivevilla15/07/2017
Walked up from the little car park at the head of Cwm Ystwyth. Up to Cerrig Gwaun-y-llan first via Cistfaen and some forest rides, then back and through the forest to Esgair Ganol and back down the same way.Neolith01/07/2017
Continuation of walk from Llechwedd Ddu. From the lane, entered field through gate and descended steeply to a col. Then a very heavy-going grass-thrash to the summit plateau. To return, tried to keep to higher drier ground nearer the forest edge, but not much better. An ascent to give a whole body work-out! With AW.marktrengove07/08/2016

After 3483. Direct route looked quite easy. Nightmare. Most of it like walking in foot deep powder snow. Grass sometimes even up to waist. Every step hard work pretty much all the way. Not recommended.destaylor11/07/2014
After Cistfaen, but around west edge of trees and more bogs. hate bogs.dicky15/06/2014
From Neuadd-ddu across the suspension bridge and up via Brithdir taking in five Deweys in a north to south loop. Glorious walking weather with blue sky and breeze on tops. Not a soul seen all day except in the valley.SS17/05/2014
Traversed, along with 4 other Deweys, on walk from Glangwy Farm Campsite to Pont ar Elan.Chris Peart26/02/2014
