The Glyders via Bristly Ridge

 

Difficulty : HardDuration : 5 HrsDistance : 8.5 Km

 
This walk is all about rock, the Glyderau mountain range in Snowdonia is one of the rockiest places you'll find on the British Isles. Some of the unique rock formations on this route include the aptly named Cantillever Stone and the awesome Castell y Gwynt. The walk also inculdes a very tough scramble up one of Snowdonias most exciting ridges, Bristly Ridge. An alternative route means the ridge can be avoided by those less experienced or in bad weather. Starting from the shores of Llyn Ogwen in the huge glacial valley below you walk up to Llyn Bochlwyd then head up to Bwlch Tryfan before tackling the grade 1 scramble up Brislty Ridge. Once on the top Glyder Fach with its famous rock formations then Glyder Fawr are within easy reach before descending past Twll Du or The Devil's Kitchen to the wonderful glacial valley of Cwm Idwal.


Full route description for this walk

 

As with most routes that start from the Ogwen Valley, parking can be found along the main A5 road in many of the parking laybys that are scattered alongside the Llyn Ogwen. At 300m above sea level this high start takes out a lot of unnessecary ascent. From the main road follow the footpaths that head up towards Cwm Bochlwyd following the side of the Nant Bochlwyd. The path will get rocky as it approaches the small waterfalls before topping out at the end of Llyn Bochlwyd with its impressive back wall of Glyder Fach's formiddable north face.

From Llyn Bochlwyd follow the path round the left side of the lake until it starts to climb steadilly towards the col between Tryfan on the left and Glyder Fach on the right, known as Bwlch Tryfan. The path starts off on easy ground but the higher it gets the harder it gets until it reaches a valley of huge boulders with a wall and stile at the end on the top of Bwlch Tryfan. Take a look to your left from the wall and stile and you will now see the start of Bristly Ridge. If you decide you cannot handle the ridge due to inexperience, fear or bad weather then simply cross the stile and turn right up a steep but clear path that will lead to the summit plateau of Glyder Fach.

Bristly Ridge Gully

Bristly Ridge is one of Snowdonias most feared ridges and once you've done it you'll have ever been scared senseless on its knife edge pinnacles and difficult climbs or have had one of your favourite and most exhilerating scrambles ever. To start the scramble you must first try to get onto the ridge proper by climbing its side. The usual rule with Bristly Ridge is that looking from Bwlch Tryfan, the furthest right you start the harder the climb. If unsure then wait at Bwlch Tryfan and watch others go first and decide for yourself your prefered route. I prefer to start somewhere in the middle, where a few gullies and chimneys lead up with good climbs on either side of them. Once on the ridge proper you can from the crest look towards the rest of the ridge and see its unbelievably spikey profile. Follow the crest where possible over some really impressive pinnacles and all the time concentrating on your next move while looking around at the breathtaking views. This really is on amazing place and the satisfaction of completing Bristly is overwhelming.

You will reach the summit plateau and head in the obvious direction of its highest point. There is no trig point at the highest point but it is fairly obvious which rocks are the highest at 994M. Close by to the summit you will wihout mistake notice the Cantilever Stone, usually with a fellow trekker stood on top while another takes there picture. In the height of summer this stone must see hundreds of people in one day and there are often queues for this unique photo opportunity. The rock looks as though it should topple over when people stand on it but after thousands of people and groups standing on it the rock still sits in the same precarious position it has for centuries.

From the summit of Glyder Fach you will see on the far western side of the mountain plateau a huge natural display of sharp slate rocks soaring skyward like something out of a science fiction movie. This is Castell y Gwynt or translated Castle Of The Winds, named due to the noise the rocks make as strong winds pass through them. Castell y Gwynt is one of the natural wonders of the British Isles and the closer you get the more you realise just how spectacular it is. There is no obvious path here but you can either skirt round Castell y Gwynt on either side or simply cross over them if you dare. On the other side there is a short steep section down onto Bwlch y Ddwy-Glyder.

From Bwlch y Ddwy-Glyder follow the obvios path as it slowly ascends the flat but rocky plateau of Glyder Fawr, the path edges the Nameless Cwm with stunning views down through the Nant Ffrancon valley. After a while you'll reach the top of Glyder Fawr, the highest of the Glyderau range at 999M. There is once again no trig point and on Glyder Fawr it isn't quite as obvious which of the few mounds of rock is actually the highest. You will realise that the summit of Glyder Fawr is not nearly as exciting as that of its smaller sister Glyder fach. From Glyder Fawr descend north west over rocky ground then along the obvious path until you reach a steep section down to Llyn y Cwn. At this point this path continues north to ascend Y Garn, however turn right here along an obvious path and the path will head towards the edge before turning into a well laid path that descends quickly down into the glacial hollow of Cwm Idwal. As the path is at its left most position looking behind you can gape into the famous gully known as Twll Du or The Devils Kitchen. This huge gully with a waterfall and stream running through it is full of mysterious mythical stories and makes a great ascent route for competent scramblers.

The path from here is very obvious as it rounds Llyn Idwal, passing the sloping stones of the Idwal Slabs on the right often with climbers and ropes hanging from its many lines. The path will continue to skirt the beautiful Llyn Idwal with its huge back walls until it reaches its outflow at which point the path now splits and goes back both ways to the main road at the start of the walk.
