During a long weekend in Wales with J, Shaky & Smithy. A sunny but breezy day. Paid the £5 at Eisteddfa Gurig into what amounted to an honesty bucket after debating whether to park in a layby further down the hill. Followed the E RoW to the summit of Pen Pumlumon Fawr for a good view, then onwards over the E top to Pen Pumlumon Arwystli. Then reversed the tops checking out the source of the Wye & descended the W RoW. I nipped out & back to Y Garn which is a nice top before cathcing the others up. Saturday night entertainment in Rhayader ensued...NotReallyABagger29/09/2018

Following my retreat from the heavy fog after making Y Garn and Pumlumon Fawr, I returned in less than a week on a glorious sunny day and bagged this along with Pumlumon Fach and Pen Pumlumon Llygad-bychan.Dewi Prysor01/11/2015

All the Pumlumon Nuttalls and a couple of extras, with Martin on a dull cloudy day, from Eisteddfa Gurig.Lou09/08/2015
With G. Parked at Eisteddfa Gurig (honesty box) > Y Garn > Pumlumon Fawr > Pumlumon Fach > Pen Pumlumon Llygad-bychan > Pen Pumlumon Arwystli then back via Pen Lluest-y-carn & good track to A44. Property (Eisteddfa Fach) where track joins A44 unwelcoming to walkers, so had to make slight detour to west onto road.RT197002/08/2015
Did the Nuttalls route from Nant y moch. No stile found and a path was there (at times) but did not appear to ascend Y Garn. It was tough ascent of Y Garn. Suggest if you are going to do the 5 tops start at Eisteddfa Grig (near ELVIS stone) 798841. Go on path to the forest and then follow the forest around. Means doubling back from Y Garn but I am sure it will be easier. Once up on top there are paths along from each top. When the last top is reached go back to the penultimate top again and then contour round to take path (path from Eisteddfa Gurig to Pumlumon Fawr) back to the start.johnjennison18/06/2015
ANOTHER GLORIOUS DAY WITH VIEWS FROM THE BEACONS TO SNOWDON. DROVE UP FROM BRECON BASE CAMP TO TOP OF PASS ON A44. CLEAR AND EASY PATH UP Y GARN VIA FOREST EDGE AND FOLLOWED FENCE UP ONTO PUMLUMON FAWR. OUT TO PUMLUMON FACH AND FOUND SHEEP TROD TO CUT OUT RE-ASCENT OF FAWR ON WAY OUT TO PUMLUMON LLYGAD BYCHAN AND PUMLUMON ARWYSTLI. EASY DESCENT ALONG FENCE TO CAR PARK. AN OUTSTANDING DAY.BURGESS08/06/2015

Started center Ponterwyd. Headed East along A44 to B4343 junction where footpath heads North East through fields (boggy section) before ascending to meet East of forest (moderate to heavy cloud, strong winds and rain).

Descended from Pen Pumlumon Arwystli along foothpath headed North and then East across VERY boggy section, keeping to the South of the stream until eventually reaching a track, closely followed by the Nant-y-moch Reservoir. Followed track and road back South to centre of Ponterwyd.Judgey9405/06/2015
Ascent of Pumlumon’s five Nuttalls with my sons (aged 8yrs & 14yrs) from Eisteddfa Gurig. Cloudy and windy on ascent of the first four peaks, very much so on first summit Y Garn. Cloud clearing off Pen Pumlumon Fawr on approach. Quick descent to Pumlumon Fach, re-ascent of Pumlumon Fawr before following ridge to Pen Pumlumon Llygad-bychan. Sun came out on traverse to fifth Nuttall Pen Pumlumon Arwystli, though wind remained strong. Returned to below Pen Pumlumon Llygad-bychan, following fence above source of river Wye and down to join track at metrological station. Followed track back down to Eisteddfa Gurig.VirtualMountain26/05/2015

Low cloud at the start of the walk but it gradually cleared to give a fine day with a cold wind. Short period of hill fog in the afternoon. Surprisingly dry underfoot despite the wettest winter on record. Very few people out as it was the last day of the six nations tournament.axe.stephen15/03/2014

Started at forestry comission carpark where the source of the Severn walk starts. Small car park but no problem with space. Toilet facilities and picnic tables at the car park. Disabled facilities and a wooden walkway allow for wheel chair access at the bottom. Lots of good blueberry picking on the way up :-). Very pretty walk through the Forested area and excellent views from the top. Some boggy area's once out of the forest but nothing too difficult to get past.kbisseker26/08/2012
