Glyder Fawr and Glyder Fach

This circular walk up Glyder Fawr and Glyder Fach presents some demanding stretches of ascent, and several portions of the route can be difficult to find, especially in the colder months when snow settles on the peaks. While not too technically challenging, walkers should have some experience with route-finding, and be comfortable tackling steep rocky scree.

As the tallest peaks in the Glyderau range, Glyder Fawr and Glyder Fach are a breathtaking pair! The former tops out at just over 3281ft, making it the third-highest mountain in all of Wales (and nearby Fach is only a few behind). In clear weather, the views over the Carneddau and Snowdon itself are nothing short of spectacular.

Start this walk from Ogwen visitor centre, taking the well-made stone path ascending to the left. This leads up to the northern end of Llyn Idwal, where it splits and continues along both shores – the left path offers a shorter distance. Not far from the southern end of the lake, you arrive at the base of the Devil’s Kitchen, a well-known section of steep ascent. You may require some mild scrambling as you climb through the cliffs to the shores of Llyn y Cwm. A great place for a quick rest, as the next section is even trickier!

Most of the following stretch from here to the summit is loose, steep scree. It’s less than 1640ft in total, but quite challenging, and without any reliable spot to rest. Pick your line carefully – a bit left of center is a good choice. Power through, and the final 328ft is a forgiving stroll to the summit. This one is a large plateau, with majestic views in all directions!

The crossing over to Glyder Fach is a relatively straightforward walk along some breathtaking clifftops. In poor weather, a handful of cairns should help lead the way. Follow these to Bwlch y Ddwy Glyder, along the top of the Gribin Ridge. A path on the right takes you under and around the peak of Castell y Gwynt, then keep your eye out for a left turn for a path leading to the top of Glyder Fach. This is a particularly unique summit, made up of an enormous boulder cairn which is quite difficult to actually climb – but the famous Cantilever Stone around its left is a must!

The descent from Glyder Fach can be tricky to find, and a few options present themselves. The quickest way (marked on this GPS) is a left along the top of the Bristly Ridge, then a right turn shortly after to descend down a rocky scree path. This is quite steep, so in poor weather (or for less comfortable walkers) turn right at the top of the Ridge instead and follow a broader path down to the Miner’s Track, which then cuts back to the left. In either case, you should end up at Bwlch Tryfan. From here, continue northwest along the path, back along the eastern shores of Llyn Bochlwyd and back to the Ogwen visitor centre.

Trail Highlights

Devil’s Kitchen
The Devil’s Kitchen is the colourful name for a crack in the cliffs, down which a waterfall tumbles over multiple drops. At times, water vapour will rise up through the crack, mimicking steam – hence the moniker.

Cantilever Stone
The summit of Glyder Fach is a unique area to explore, with the famous Cantilever Stone a notable highlight. As the name suggests, this boulder sticks out horizontally at what seems like an impossible angle. This location was used in the Walt Disney film Dragonslayer, as an entrance to the dragon’s cave – very fitting for an iconic Welsh sight!
