Deceptively difficult little hill. Climbed from campsite owned by the Cwellyn Arms by Llyn Cwellyn. Access from the NE was prevented by deep bog, so I crossed at a disused dam to the north and made my way up by very steep heathery ledges to the N. Ascent from the E or S looked barred by crags.Wheelsy23/08/2017
From Rhyd-DDu,on my own, cool but sunny.alwaysinshorts21/04/2017
Overcast, calm, 9 degrees. Nice little climb from car park by Llyn. Bigger than it looks. On to Bryn Gwyn.Wycombe Wanderer06/04/2017
With Bryn Gwyn. Very steep sided little hill, ascent easy, descent not quite soJamesD197218/01/2017
On way down from Mynydd Mawr with Matt H. Had the misfortune to meet a shepherd in the field to the N who told us that the 'bridge' at SH556539 was on private land but that we could go round by the NE flank of the hill. The flat area on the map turned out to be a thigh-deep bog. Then a very steep climb up boulders and steep grass to a good summit.Mark Jackson23/08/2016
From Bryn Gwyn up the rubble heap. Two enjoyable hills to start the day.Herbert Anchovy03/06/2016
