Tryfan – 917.5m Grade 1 Scramble

Tryfan, Eryri (Snowdonia) – Beginner scrambling day with Snowdonia Walking and Climbing – 917.5m Grade 1 Scramble

UK Iconic Walks – Welsh 3000s – Welsh Marilyns

The mighty Tryfan. 917.5m of pure rock playground in the Glyderau range of Eryri/Snowdonia. It’s got the reputation as ‘Britain’s favourite mountain’ and for those with a head for heights and who aren’t afraid with scrambling their way to the summit it’s not hard to see why.

There are no paths, no waymarkers, and no real sense of direction other than up or down. Knowing it isn’t a mountain to be messed around with and commonly the site for many mountain rescue call outs to lost, cragfast or in some cases severely injured hikers… I chose to join Snowdonia Walking and Climbing for their beginner scrambling day and for my first taste of true scrambling.

Best decision ever. Dewi was not only highly experienced and capable of guiding/teaching us the skills we needed to safely climb, but he was endlessly patient and supportive to everyone in the group.

Tryfan’s ascent via the North Ridge route has an typically Grade 1 rating amongst mountaineers, the title can be misleading as the route can become significantly harder depending on the conditions and the exact line taken. The ridge has countless variations, with some sections approaching Grade 3 rock climbing difficulty if tackled directly. Route finding one Tryfan is one of the biggest hazards as people often attempt to bypass harder sections and accidentally move into dangerously exposed terrain like North Gully or loose gullies on the west side. The North Ridge as a descent in particular can be especially dangerous, with Ogwen Valley Mountain Rescue responding to a huge number of incidents on and around Tryfan every year. Their public incident log shows repeated rescues specifically on the North Ridge, often involving walkers becoming cragfast (stuck unable to climb or descend), lost, injured, or stranded in darkness. In the first few months of 2026 alone, the rescue log recorded multiple separate incidents on Tryfan’s North Ridge involving slips, falls, navigation errors, injuries, and people stranded on steep ground.

But before anyone complains about mentioning the negatives, the reason I do is important. Tryfan is a mountain that demands, and requires, respect to be able to fully and safely enjoy it. Despite its intimidating reputation, thousands of walkers safely complete the North Ridge every year. In good conditions, with sensible route choices and preparation Tryfan is regarded as one of the best introductory scrambles and for many people, the North Ridge is the moment hiking becomes something bigger. The scrambling on Tryfan is often described as surprisingly solid and confidence building when done with the right preparation, respect and equipment. Much of the rhyolite rock offers excellent grip, especially in dry conditions. Unlike many hikes where you simply walk to a trig point, Tryfan truly is something special and feels like real mountaineering. There’s no easy to follow OS map path, GPX can’t be relied on to keep you safe, and every step you take requires thought and careful planning.

My takeaways from my time on Tryfan for anyone reading this and considering taking it on.

If it’s your first time, go with a experience guide. Not some dude you met on Facebook and saw it on Tiktok. People have died, and sadly will continue to die on Tryfan and some of these will have been avoidable. Many rescues happen because someone underestimated the mountain or overestimated their own abilities.
SUITABLE FOOTWEAR IS ABSOLUTELY ESSENTIAL. You need grip on rock. One slip is all it can take to be injured or worse.
Prepare for the worst. First aid kits, survival bags, headtorches, extra batteries, powerbanks, waterproofs. Crocs and tracksuit bottoms will not keep you alive if you have to wait hours for mountain rescue because you got lost or hurt yourself.
Take multiple pairs of gloves. The exposed rock, wetness and cold is harsh on your hands and you need those hands to be functioning properly when you’re using them to climb. I ended up going through 3 pairs of gloves in mid-May.

– Plan, prepare and most importantly ENJOY your time on the mountain by being safe. Don’t become a mountain rescue statistic. –

Despite the horror stories and danger, here’s the main reason that I’ve fallen in love with Tryfan. It’s beyond hiking. Every movement you make is an adventure, tactile, playful and three dimensional rather than just following a path uphill. While Yr Wydffa’s Pyg and Miner’s tracks were amazing routes, there isn’t anything I’ve experienced that even comes close to be as one with nature and the wild. You are mentally and physically grounded to the mountain when you’re on Tryfan. I had many moments on the mountain where I had the realisation that one wrong footing or shift of a rock could have meant serious injury or worse. Despite that, with the expert guidance and support of our guide Dewi, at no point did I feel unsafe or nervous about following him even when the scrambling got more technical. If anything, I had so many moments where I caught myself thinking that I had never felt so alive as I did right there on that mountain. I would do it all again in a heartbeat. In fact, I’m already eyeing up another trek with them to take on Crib Goch…

We definitely left our comfort zones in the car park and am SO glad we did. I’d never have imagined being able to tackle something like Tryfan, and even that same more I had moments of feeling like I should cancel because I’d be too slow/unfit or hold everyone else back by being inexperienced. That’s where the right guides can make the world of difference to your experience, confidence and why I wouldn’t hesitate to recommend the team at Snowdonia Walking and Climbing to those looking to take on their next big adventure.

I’m immensely proud of myself, the group and my ongoing pursuit of proving that I’m capable of doing hard, scary things I’d previously only dreamt of.
