Vaguely followed the PRW from the car park beneath the quarries. Stunning views.Rob Rees04/01/2022
Gentle reintroduction to the Welsh hills after latest lockdown. Parked in the Llangatwg Quarry Car Park, headed up to the Lonely Shepherd then across to Twr Pen-Cyrn. Came off the hill using the North-South path, then back under the escarpment. On my own. Sunny to start with, becoming more cloudy and threatening later.clyoung12/05/2021

Family walk from the car park below the quarries to the NE. Had lunch in the sunshine in the quarries and then headed up to the summit for cakes. Was the best place to be on a day like this as nice breeze on the top on a very hot day.Herbert Anchovy20/04/2019

Parked in car park at 208153 – W. along former limestone quarry track for ½km to remains of old quarry buildings – Up path which skirts W. end of quarry & then along intermittent path to the trig point. (S)gerrybowes29/09/2017
Started at car park at 208153, headed SE then up on to the escarpment. Summit easily bagged, things went a little awry as we tried to find our way NW along the plateau to head on down to the road and then back through Craig y Cilau Nature Reserve. Found Eglwys Faen on the way back to the car.clyoung16/07/2017

Couldn't find the start of the path from Pant-y-rhiw so headed straight across moor. Not good hummock grass, heather, braken etc, etc oh and ann adder. Found a path on way back made life easier.MikeM01/05/2015

After a 3 mth break (knee op, car crash) nice looped walk up from Crickhowell town to make it a 8 miler. I know hill-bagging is what it is, but whats the point in driving to the top... I won't catch Anton now after 3 months off :-(dicky24/11/2013

Birthday walk with Patricia followed by meal in Llanwenarth Arms Hotel. Super meal, average hill.arranc02/10/2012
Parking to NNE. Track to start through the grassed slag heaps. Amazing place - a lot of hard work has been done there. Then the path not very good after the rock edge. Bits and pieces then all the way. Heather around.destaylor24/08/2012
Parked in the car park to the north having driven in on the steep and narrow road from Llangattock. Explored the cave entrance first then over the moor to the sroney top. Two massive shelters enough for everyone in Wales adorn the topFather Ted22/07/2012
Easy parking at the start of the footpath to Cairn Mound Reservoir. Easy hike, beautiful views to the north.Tracey08/04/2012
