Over the last couple of days the Cuillin Ridge has been busy, with many teams making the most of the sunshine and attempting the traverse.
Ossian, Cam, and I headed up into the heat and glorious blue skies alongside many others. Having seen the forecast, we’d stashed around 9 litres of water along the ridge the previous day and set off well before dawn to make the most of the cooler morning air.
By the time we reached An Dorus at around 1:30pm the heat was intense, so we stopped there for over two hours to eat, rest properly, and rehydrate before continuing on towards Bealach Glac Mhor once the day had begun to cool.
Sometimes good progress in the mountains comes less from constantly moving, and more from knowing when to slow down.
We all love those perfect blue sky mountain days — but are they actually the easiest conditions for a Cuillin traverse?
A few things worth thinking about on hot, cloudless days in the Cuillin:
• There’s very little reliable water available along the ridge itself apart from around An Dorus and Bealach Glac Mhor. Stashing water beforehand can make a huge difference.
• If you’re relying on the water sources at An Dorus or Bealach Glac Mhor, it’s worth knowing where they are in advance rather than searching while already dehydrated.
• Large sections of the scrambling and climbing are exposed to direct sun for much of the day, with very little shade. Even in the heat I’ll often wear a lightweight long-sleeved top to protect my arms and neck.
• Sweat, movement, and constant exposure quickly reduce the effectiveness of suncream. Reapplying regularly really matters.
• Heat quietly drains energy, concentration, and decision-making. Taking proper breaks can make a significant difference to how people move and think later in the day.
• If caching water or supplies beforehand, remember to remove everything afterwards.
Thankfully the three of us completed the traverse successfully and made it back to the Sligachan for around 3pm today.
Great to see so many teams out enjoying the ridge in such beautiful conditions.
Stay safe out there.
