The weather forecast for this walk was for rain, on and off, which should have convinced me to not do a mountain top route over the Glyderau, but the winds were not too high and after almost three weeks on the Cambrian Way I wanted to keep to the correct route. When I first attempted to do the Cambrian Way last year bad weather intervened which prevented me from following the route throughout most of Eryri (previously known as Snowdonia). This year, so far, I was more successful, but I still encountered bad weather in southern Snowdonia which had prevented me from going over Cadair Idris so, if possible, I wanted to keep to the route for the rest of the Cambrian Way. The penultimate stage of the Cambrian Way starts from Pen-y-Pass, but a lack of accommodation at the youth hostel meant I had spent the night at the Dinorwig Hostel above Llanberis. Rather than going via Pen-y-Pass I decided I would take the direct, mountain top route over Elidir Fawr and Y Garn, which initially meant heading north before turning back towards the mountains on an access road for the Marchlyn reservoirs. At Marchlyn Bach Reservoir I turned right to climb along a clear path heading south towards Elidir Fach with views behind me out to sea while temporarily enjoying an easing of the rain.
There were many places on this walk when I could or should have turned off the treacherous mountain top route and the first of these was at the start of the access road where I could have followed the Snowdonia Slate Trail to Bethesda, which is what I did last year. Instead I slowly headed up to Elidir Fach, soon disappearing into the clouds, and at the top I turned left to follow a fence steeply up the hillside as the rain inevitably came back. Despite the promise of low winds, this was a blustery location which gave me a lot of problems as I tried to put my waterproofs on. With hindsight, I should have put my overtrousers on before leaving the hostel and as a result my trousers stayed wet for the rest of the day. I got very annoyed and frustrated with my difficulty in putting my waterproofs on in the windy weather but eventually I was ready and set off up the stony hillside. The wet conditions meant the rocks were very slippery so I had to take extra care as I climbed up to the summit ridge and along the top in the murky weather. I love Elidir Fawr as it feels like a proper mountain, like a Munro in Scotland, but I often have bad weather when climbing it, so I want to return some time in good weather so I can really appreciate its merits and this route up appears to be the best. Eventually I reached the stone shelter that marks the summit and since it was already almost noon I stopped there to have my lunch.
When I set off again I slowly made my way along the bouldery ridge until I eventually came off the rocks and onto a path which negotiates an excitingly narrow ridge with glimpses through the clouds to my left down to Marchlyn Mawr Reservoir. As I crossed the head of Cwm Dudodyn I was rather frustrated to see the sun shining in the valley, around Llanberis, while I brooded under dark clouds with rain never far away. At the lowest part of the col I saw the stile I had crossed last year after passing over the windswept hills of Carnedd y Filiast and Mynydd Perfedd. I had escaped the winds on that occasion down the grassy slopes into Nant Ffrancon and I could have taken the same escape route this year, but instead I kept going along the ridge, though I bypassed the minor top of Foel-goch, before climbing the zigzags all the way up to the top of Y Garn while the weather slowly improved around me. At the summit I was astonished to encounter some people, my first of the walk, with many more wearily climbing the broad grassy slopes on the other side. At Llyn y Cŵm, at the bottom, I could have turned left into Tŵll Du, the Devil’s Kitchen, but this was another escape route on this walk that I ignored as I set off up the horrible scree slope of Glyder Fawr. This is one of the worst paths in Britain, either in ascent or descent, and so I soon wished that I hadn’t decided to take this route. Initially it zigzags up a scree slope but eventually deteriorates into a steep, featureless slog on a path that is heavily eroded down to bare earth.
Half way up it started to rain again, which just added to my misery, as I slowly headed up to the summit of Glyder Fawr. The Cambrian Way takes a different route up Glyder Fawr, climbing the southern slopes from Pen-y-Pass and now I wished I’d taken that route, which I have previously taken only once before, back in 2006 in descent. With the rain now falling quite heavy, I made my way across the barren summit to Bwlch y Ddwy-Glyder where I was confronted with a wall of rock and no sign that the path ascends that way, but I knew that I had to scramble up the rocks. Trusting in my memory of the route and taking extra care on the wet rocks, I scrambled up and after a brief rest, and a check of my bearings, I continued the scramble until I reached the rocks that mark the summit of Glyder Fach. This was a very difficult place to walk in this treacherous weather and so I couldn’t help thinking of all the opportunities I had ignored to escape this torturous terrain, but I had no choice now except to keep following the route of the Cambrian Way and trust in my experience of walking in mountains to see me safely down. The path eventually led me to a large cairn where a trail of helicopter bags seemed to mark where a path was being constructed, however this didn’t match the path marked on my map so I stayed at the top of the ridge until I reached a much more slender path which finally swung into Cwm Tryfan to descend across the steep hillside, but this was a very difficult path to follow in the wet weather.
Further down I came upon a clear manufactured path, the bottom of the path I had seen earlier, and probably should have taken, but the good path was short-lived and soon I was struggling again along a narrow, rough path until I eventually reached Bwlch Tryfan. A good, manufactured path led the way beyond, but was still slippery in the wet weather, although the rain had now eased as I slowly made my way down to Llyn Bochlwyd and the path continued beyond beside Nant Bochlwyd on a tricky, steep descent until eventually the gradient eased and I was finally able to accept that I had survived a traverse of the Glyderau in wet weather. It has been said that I am a fair weather walker because I will usually not go walking in bad weather, which is true. I walk purely for pleasure and not to challenge myself so I don’t see the need to walk in bad weather, which is why on the Cambrian Way I didn’t go out of my way to reach every checkpoint if the weather was not right. This is my holiday and I do this for enjoyment, so I don’t care if I miss a few checkpoints so long as I am enjoying the walk. However, on this walk I had challenged myself to keep to the mountain tops despite the bad weather and I survived and my waterproofs kept me dry, except where I had failed to put them on in time, though I was very relieved to safely reach the youth hostel at Idwal Cottage.
