O: I thought pasture E of hedge although MP survey is W side. Probably similar. i.e. ground 30m ENE of current GR 10 may be as high. Didn't have hand level with me.

Decent parking in Waen & up concreted track to boarded up gate just before Gelli Farm - ENE on RoW, up through open woodland & over wooden fence/bwf - WSW to to summit GR which lies on W. side of fence. Gate adjacent to boarded up gate would have been better option.gerrybowes15/01/2023
FromWaen where there is plenty of parking. Almost up to Gelli Farm and then into field with a couple of inquisitive horses.Campbell Singer20/01/2022

Parked to north, down slightly to a horse exercising area then up a field where the sheep were very friendly then over a fence and up to summit.clivevilla05/01/2021
Domed grass by a hedge near a small reservoir with good farmland views. Both sides of fence seems of similar height.Denise 02/02/2020
From Gelli Farm, gate E into pasture. Grassy rise on W side of fence very similar in height to fence line on E side of fence. Good if somewhat grey views.RichardM02/02/2020
Approached from Tredeweren Springs side, pleasant walk up RoW, no livestock other than sheep on one of the two possible summits. Nice view, can see the chimney in Oswestrytumpawumpa20/04/2019
Unticked. I guess I am just too scared of farmyard and horses. Tried from Gelli farm, couldn't find public row off bridlewaytumpawumpa07/04/2019
