Craigysgafn: The Rocky Spine of the Moelwynion
Perched between two towering peaks in the Moelwynion range, Craigysgafn is a rugged, rocky ridge that offers a thrilling hands-on experience for those with a taste for adventure. Stretching from the summit of Moelwyn Mawr towards Moelwyn Bach, it’s often overshadowed by its taller neighbours, but for many walkers, it’s the highlight of the whole route.
The Journey to the Top of WalesA Narrow Ridge with Big Drama
Craigysgafn’s steep drops, jagged edges, and narrow spine give it a mountain character that feels far bigger than its height suggests. The ridge forms part of the popular Moelwyn loop and is best tackled as a short Grade 1 scramble, offering exhilarating exposure and panoramic views across Snowdonia.
From its rocky crest, you can see down into Cwm Croesor, across to the Rhinogydd, and even spot distant peaks in the Snowdon Massif. It’s a route that rewards confident scramblers with a real sense of mountain excitement, without the heavy crowds.

What to Know Before You Go
Craigysgafn is a Grade 1 scramble with some exposure, making it best suited to experienced hillwalkers or those confident on hands-on terrain. Scrambling experience is strongly recommended, as the ridge involves steep sections and narrow paths. Navigation can be tricky in poor visibility, so be sure to bring a map and compass. The rocks can become very slippery in wet conditions, so it’s safest to tackle the ridge in dry weather with clear views for both safety and enjoyment.
Why We Love Craigysgafn
It might not have a summit cairn or official trig point, but Craigysgafn delivers one of the most thrilling ridge scrambles in southern Snowdonia. It’s raw, rugged, and always memorable, especially with the sharp drop-offs and the stunning backdrop of the Moelwynion peaks all around. It’s a proper mountain experience in a quieter corner of the national park.
How to Get to Craigysgafn
The best starting point is the village of Croesor (postcode: LL48 6SR), located at the southern end of the Moelwynion range. There’s a small car park in the village with an honesty box. The paths are well-marked initially, but become rougher and less defined as you approach the ridge.
Public transport is limited in this area, so driving is the best option. Be sure to arrive early on weekends and holidays, as parking fills up quickly.
If you’re travelling by public transport, the nearest train station is in Bangor, from where you can catch a bus to Llanberis. Sherpa buses also link the main trailheads, including Pen-y-Pass and Snowdon Ranger.
A Bit of Craigysgafn History
The name “Craigysgafn” loosely translates to “bare crags” or “bare rocks”, a fitting title for a ridge so defined by its raw, exposed stone. The surrounding area is rich in quarrying heritage, with the remains of old slate workings visible throughout Cwm Croesor and the neighbouring slopes. Today, Craigysgafn stands as a natural feature of adventure and beauty in the heart of one of Snowdonia’s most underrated ranges.
