Glasgwm, Aran Fawddwy, Drysgol & Pen yr Allt uchaf.Yr Eryr Aur22/10/2023
This was a lovely walk. Climbing the western Arans from Cwm Cywarch gives a lovely approach. I climbed Gwaun y Llwyni, Waun Camddwr, Aran Fawddwy (a good view today, so I climbed it again), Gwaun Lydan and Pen yr Allt Uchaf. All finished off with a very steep drop on the northern grassy slope of Pen yr Allt Uchaf.oldbagger2720/06/2023
First summit of the day, parked up in the free car park in cwm cywarch, nice easy going hike until you turn right at the stlye 1.5 miles in, tough going up the grassy hill with the summit on the topBuckleymon09/02/2023

From Gwaun Lydan. Boggy walking in the mist, a tracked vehicle has made even more of a mess of the bog of Waun Goch. Descended north west to path. Met a couple of chaps who'd summited Aran Fawddwy and there had not been a cloud inversion so decision vindicated. 15km 5 hours.Wycombe Wanderer22/01/2022
A windy day with the odd snow flurry but pleasant enough. Via track running along NW flank and then straight up fence from the stile to fence corner on ridge then short if windy walk to top.dickscroop04/01/2022
Nuttall walk 8.1.Pen yr allt Uchaf. Gwaun Lydan. Aran Fawddwy. Erw y Ddafad-ddu. Aran Benllyn. Gwaun y Llwyni and finally Waun Camddwr. With Hiking Manchester. Glorious weather and great company.Lazylizzie24/07/2021

From SW, revisit for the 616m top, which is on John Gillham's list and possibly also a NuttallRHW11/06/2021
Nuttall's routes 8.1 and 8.3 combined plus a few extras - Pen-aran (at the end of the main ridge - a Bridge), Pen y Byn-fforchog North Top (a Bridge) and Y Gribin (a simm). 12 peaks - 29.93km - 5500 feet - took just under eleven hours (the GPS reckoned three hours were spent sitting on my backside!). Lovely sunny day until I got to Pen y Byn fforchog when the cloud descended and it began drizzling. Route through the forest was horrible.Herbert Anchovy31/07/2020
From national Park car park SH880298 (further up valley than my edition of Nuttall book suggests), on via Gwaun Lydan, Drysgol, Gwaun Y Llwyni, Waun Camddwr, Glasgwm and Pen Y Bryn Fforchog. A great horseshoe round the edge of the Cwm rather than following Nuttall route in order to 'save' Arran Fawddwy as my last 2,000 footer the following day.Neil Midgley30/07/2020
From Cwm Cywarch car park. Circuit of Y Gribin, Glasgwm, Waun Camddwr, Gwaun y Llwyni, Aran Fawddwy, Geaun Lydan and Pen y Allt Uchaf. Direct descent off NW of Pen y Allt Uchaf.welshyboyo17/07/2020
1/7. As per Nuttall book. Pen yr allt Uchaf. Gwaun Lydan. Aran Fawddwy. Erw y Ddafad-ddu. Aran Benllyn. Gwaun y Llwyni and finally Waun Camddwr the ex Nuttall. Great walk loved waterfalls on descent. Misty but mild.nickywood125/09/2019

From the free car park at the end of the minor road in Cwm Cywarch three miles north of Dinas Mawddwy.WAYNE ROWLETT29/06/2019
After a long climb up from Ty'n y Maes. First hill on a circular walk from the car park at the end of Cwm Cywarch ( not marked on our OS map - portaloos! ).DanMaisieBex22/06/2019

Final top, diversion at the end of a round of Cym Cywarch, fine outing. Steep down hillside to regain path and track to the Park CP near the head of the lane.nordicstar12/07/2016
ANOTHER BEAUTIFUL DAY WITH GOOD VIEWS. FOLLOWED NUTTALLS WALK 8.1 UP THE STEEP GRASS ONTO PEN Y ALLT UCHAF, THEN EASILY OVER GWAUN LYDAN. A STIFF CLIMB ONTO ARAN FAWDDWY, THEN EASY RIDGE WALKING TO ERW Y DDAFAD DDU AND ARAN BENLLYN WITH GOOD VIEWS OVER BALA, RHINOGS AND ARENIGS. RETURNED AVOIDING SUMMITS TO DESCEND STEEPLY AND THEN OVER ROUGH GROUND TO GWAUN Y LLWYNI AND EASILY TO WAUN CAMDDWR. DECIDED TO TAG ON WALK 8.3 TO AVOID RE-ASCENT AND TAKE ADVANTAGE OF FINE WEATHER AND LONG JUNE DAYLIGHT. A VERY HARD CLIMB ONTO GLASGWM, THEN EASY RIDGE TO FINISH ON PEN Y BRYN FFORCHOG. HOWEVER, THE FOREST HAS BEEN FELLED AND IT WAS VERY TOUGH GOING TRYING TO FOLLOW THE PREVIOUS RIDES UNTIL THE EASY DESCENT OF THE ZIGZAG - 10.5 HOURS WALKING.BURGESS15/06/2015

A reduced Aran Ridge walk with Lindsay and Steve taking in Pen yr Allt Uchaf, Gwaun Lydon, Gwaun y Llwyni, and Waun Camddwr. A rare wet foot day the rain was so bad.knarf25/01/2015
Up from car park at end of Cwm Cywarch, up the Aran Fawddwy path, over the fence and across country to Gwaun Lydan, across country to Pen yr Allt Uchaf and then down the path south of Nant Terwyn. All the way down, difficult to believe that the NE top is the highest, but it is!tsharp18/01/2015

On own. Starting from Cwm Cywarch, southernmost four tops on Nuttalls walk 8.1. Then added walk 8.3. A long hard walk, but really enjoyable in dry sunny conditions.Crib Goch21/04/2014

Nuttalls walk. Supposed to be sunny but spent a lot of time in the mist. Worth it for the occasions when the mist cleared.johnjennison03/09/2013
Circuit from Cywarch,6 tops in total.Emlyno16/08/2013
First time I've had to abort a walk because of the heat! And in Wales too!! Had hoped to do the full Nuttall walk taking in the ridge. But with no shade, no breeze and no phone signal, after dragging myself up Pen Yr Allt Uchaf, I decided to just take in one more (Gwaun Lydan), and retreat down Hengwm to a welcome drink at Dinas Mawddwy. The ridge awaits another visit.ruthatlast12/07/2013
Cloudy day saw me follow an anti-clockwise loop. Skipping Aran Fawddwy in the end as the wind was up and I couldn't see anything. Four more bagged so six to go.SS04/05/2013
