Crib Goch is the hardest route up Snowdon and starts from Pen-y-Pass along the PYG Track. It’s an exposed grade 1 scramble that should only be attempted if you’re confident in your abilities.

NOTE – Distance above is for one way only. You’ll need to double up if you descend the same way – but we don’t recommend it as a descent, not when it’s busy.

How Long Does Crib Goch Take? We reckon 3 hours would be a good time for a first traverse for a fit walker, who doesn’t have difficulty in finding the route. But! You will need to allow for the time of day/year into account as the sheer volume on the ridge will slow you down. Enough of these will be inexperienced enough to make the going slower.

When’s the Best Time to do Crib Goch? When it’s dry and the wind’s calm. You should also start very early in the morning, or the more confident walker can ascend it safely in the evening during the summer months. You should have it largely to yourself at that time of day.

How Hard is Crib Goch? It’s regarded as a Grade 1 scramble, the least technical grade (notice we didn’t use the word, easiest for good reason!) For experienced scramblers with a head for heights, it’s decent day out in dry weather. In anything other than ideal conditions, it becomes a different proposition. Under winter conditions, it’s an alpine traverse that requires winter climbing skills and beyond what’s considered safe for ice axe and crampon winter walkers.

What’s the hardest section of Crib Goch? For some, the entire traverse! While it’s often described as being similar to walking along the apex of a roof, that’s a roof with a wide apex. There’s a ‘bad step’ that’s no more than part of the scramble for seasoned mountaineers, just below the crest. The crossing of the pinnacles, especially the airy step to climb the first pinnacles is often thought of being the toughest section. Don’t however underestimate the scramble up Crib y Ddysgl, as this involves a fair bit of scrambling.

This is the iconic Snowdonia route – the must do route. Descend via Y Lliwedd in order to complete the famous Snowdon Horseshoe.

  1. […] route above takes you up Crib Goch initially and then over Garnedd Ugain and Wyddfa, but you could just as easily ascend the PYG track […]
