Snowdon Horseshoe by night

13-14/7/95 Hill walking in the dark

J. Parkinson and I, at this point in time busy people working for a living and raising kids, wanted to get away hillwalking, but we found that the time could not so easily be spared. After our successful overnight assault on Nevis of the previous year, we thought we might resolve this conundrum (and spend less time away) by the simple expedient of doing some classic hill-walking overnight. On this occasion we did the Snowdon Horseshoe; on another, we made a noteworthy attempt on Idwal Skyline, and bailed after rather too long spent on Tryfan – of which more later.

We left Derby at 7.35pm. We parked at Pen-y-pass and started up the PYG track at 11.30pm. The drive in along the coast road had taken 2 hrs 40 minutes. There was some moonlight on the climb up to Crib Goch. We had of course deliberately chosen a clear night as near as was practical to full moon. I walked in up the PYG track, and out along the Miner’s Track, in trainers, only using big boots for the actual route itself.

Unfortunately the moon disappeared behind clouds and our traverse of Crib Goch was accomplished in darkness without benefit of moonlight. It was windy; both of us found Crib Goch technically very demanding in the dark. Scary, in fact.

Up and over Crib-y-ddysgl, up the railway and onto the summit, which lost it’s cloud cap only while we were there, about 3a.m. We found that route-finding on the ridge was impossible by torchlight; there was no way of looking ahead. The light of dawn started to appear as we crossed from Snowdon (Yr Wyddfa) to Y Lliwedd. As we descended from Y Lliwedd, there was beautiful, transcendent morning light. We were back at Pen-y-pass at 6.40am. Seven hours on the hill.

On another occasion – I can’t find any paper notes for this but I remember doing it – we decided on an attempt on Idwal Skyline in the dark. We picked a moonlit night of course, and set off from Derby, arrived in Snowdonia, parked up at Milestone Buttress, and set off up the North Ridge of Tryfan.

The North Ridge…what we hadn’t bargained for, what we had not implicitly understood, was some basic astronomy. The moon shines from the same direction, more or less, as the sun. It is never found in the north in the Northern hemisphere. I ought have known this, having worked at or near the equator and seen the rather odd spectacle of the moon being DIRECTLY overhead – something you’ll never see the UK. Ever tried climbing the North Ridge of Tryfan in the dark? Don’t. A fit party might climb the North Ridge from the road to the summit in slightly over an hour. I’ve done it many times, summer and winter, in between 70 and 90 minutes. It took us three hours. That was a salutory lesson. Wisely we opted not to climb Bristly Ridge. We descended to Bwlch Tryfan and from there straight back down to the road.
