Great slate summit pillarBaggerGutt04/12/2023
Parked in layby opposite Boston Lodge Halt. SSW on footpath until slate steps on left leading onto footpath heading east. Unmistakable summit with slate pillar.jrj16/10/2023

Parked in the lay-by opposite the station, over the tracks and through the gate marked Portmeirion. I took a wrong turning and had to circumnavigate some highland cattle and another field with one in it. Presumably the bull.clivevilla05/12/2022
Parked in lay-by near railway works, then easily up tracks and paths to summit field graced by slate post.Views obscured by trees and low cloud. Windy but mild day.catman26/10/2022
Out and back from Minffordd. Nice standing stone on the summit.Moorponder09/10/2022
From lay-by on road to NW, over railway and through gate on track, then left through another gate and up to post at top. Quick up and down.PeterD16/08/2022

With Rufus from lay-by to NW just after bridge. ROW towards Portmeirion and gate with short path to summit on left. Actually not that great of a view due to all the trees but Moelwyn Bach & Mawr looking grand.jacobrichmond04/09/2021
Parked in a layby before Minfordd. Walked up the rd via ROW. Crossed the train track and followed the path to Portmeirion. But went to the summit of the hill, easy.Skarletk24/08/2021

From NW, layby, track, path L accessing pointed 4m slender slate post with faded red paint, at summit in pastureRHW16/12/2017
Solo: Penrhyndeudraeth - Pen-y-bwlch - Pen Ty-fry - Ynys Berfedd - Penrhyn-isaf - Porthmadog. After the horrors of the previous four hills it was a relief to have one so close to a ROW and accessible without climbing a single fence. Strange pillar on summit.Mark Jackson22/08/2016
Parked across from Boston Lodge station on the A497 before using footpaths to get very close to the tall and thin slate obelisk which marks the summit.Dugswell216/11/2015
Ran over the Cob from Porthmadog and followed paths up from behind Boston Lodge. The top seemed to be in a field marked by a tall, thin slate obelisk.Herbert Anchovy16/02/2015
Passed over this one without realising it on a walk from Porthmadog to Portmerion many years ago.Jake99404/04/2005
