The Bwlch Main (south west ridge) is a great way to descend from the summit of Snowdon, particularly on a winter's day. Great views all the way to the Irish Sea

🥾Bwlch Main (Welsh: “narrow pass”) is the exposed ridge that connects the upper slopes of the Rhyd Ddu Path to the Snowdon summit. A narrow crest with steep drops on either side, making it both dramatic and challenging. The ridge is roughly 500–600m long and feels like a true alpine section compared with the grassy and stony lower parts of the trail. 👥 Quiet & scenic: Unlike the “motorway” feel of the Llanberis Path, Bwlch Main gives a real mountain experience with the thrill of exposure. For experienced hikers seeking an exhilarating experience, it significantly quieter (albeit much easier) than Crib Goch. 👁️🗨️ On a clear day you can see the Nantlle Ridge, Moel Hebog, and across to the sea. Looking north, Llyn Cwellyn and the ridges rolling out towards Anglesey. ⚠️ Dramatic ridgeline section: The path to the top of Snowdon from this ridge includes the Llechog ridge, which provide exposure (drops, narrower path sections) the narrow section gets to only a couple of feet wide. You will need a good head for heights! And some boots with good grips for some looser rock or scree sections. Check the mountain forecast before heading out 🌬️ In high winds, the ridge can feel intimidating and unsafe. 🌧️❄️In ice, snow, or heavy rain, the narrow path and sloping rock become treacherous. 😶🌫️ Cloud / fog can reduce visibility and make it psychologically harder. To sum up: The Bwlch Main ridge is one of Snowdon’s most thrilling features. It adds a real sense of adventure to the Rhyd Ddu Path. On a good day, it’s a highlight: airy, beautiful, and memorable without being a true scramble. But in poor weather, it can turn from exhilarating to dangerous very quickly. For experienced walkers in fair conditions, it’s one of the most rewarding routes to the summit. For those with vertigo or less mountain experience, it may be better admired from afar.

Rainbows on mountains tend to be a mixed blessing as they are a pretty sure sign that you are about to get wet! However from the photographers point of view they can also signal some great light, with sun mixed in with dark moody clouds. This was the view from near the summit of Cnicht - otherwise sometimes called the Welsh Matterhorn due to its pointy appearance from the village of Croesor. To the right of the picture is Moel Hebog which rises steeply above the pictuesque village of Beddgelert.

A fine rocky and in places narrow ridge, and you will often have it all to yourself!

Beautiful hike, too bad it was cloudy at the top. 12.3 km isn't the actual distance you'll be hiking: it's definitely 10 km more because you can't walk a straight line on this path. It's very busy on this trail; there's a queue to reach the top.

Crazy hiking all the way up and then seeing a train pass you on the final section!

If you want to park here, you have to reserve a parking space in advance for 20 GBP. We didn't manage to do it, as everything was fully booked. You can then park in Llanberies and take the Sherpa Bus S1 or S2 to Pen y Pass. The bus runs every half hour. From Pen y Pass, you can then choose the Miner's Track or Pyg Track. Have fun!

Currently parking is pre-booking only! All others are directed to the P+R in the village and need to get up by bus or walk.

The mountain passes around Ffestiniog offer a diverse range of hiking experiences. You'll find everything from challenging ridge walks with exposed sections, like Bwlch Main Ridge, to more moderate trails. Many passes serve as trailheads for major peaks, including routes up Yr Wyddfa (Snowdon) from Pen-y-Pass. The terrain often features rugged landscapes, ancient slate workings, and dramatic elevation changes.
While many passes offer challenging terrain, some sections or nearby areas can be family-friendly. Pen-y-Pass, for example, is a popular starting point for the Miners' and Pyg Tracks, which have varying difficulty levels, with some parts being more accessible. For easier walks, consider exploring the lower sections of trails originating from passes, or look for routes in the broader Ffestiniog area that are specifically marked as easy, such as the 'Tanygrisiau Reservoir Loop Trail' found in the Hiking around Ffestiniog guide.
The passes are rich in history and natural beauty. Crimea Pass itself is notable for its name, linked to the Crimean War, and the stone walls reportedly built by Russian prisoners of war. You can also find 'Boot Hill' nearby, a peculiar mound of old boots with a fascinating local legend. The area also features ancient Roman presence and industrial heritage from slate quarrying. For natural landmarks, Cnicht Summit, known as the 'Welsh Matterhorn,' offers stunning views and a distinctive peak.
Many passes offer breathtaking panoramic views. Crimea Pass provides vistas of the Glyder Range and, on clear days, even the Snowdon massif, with ample lay-bys for stopping. Cnicht Summit is renowned for its wonderful views across the Moelwynion range and beyond. Bwlch Main Ridge also offers significant views with steep slopes on either side, providing a dramatic experience.
Beyond hiking, the Ffestiniog area offers excellent opportunities for cycling and gravel biking. You can find challenging routes like the 'Dolwyddelan & Pont y Pant loop' for cycling, or explore gravel biking trails such as the 'Dolen Machno Fire Road Climb – Penmachno Trails loop.' For more details and specific routes, check out the Cycling around Ffestiniog and Gravel biking around Ffestiniog guides.
The best time to visit is generally from late spring to early autumn (May to October) when the weather is milder and more predictable. During these months, you'll experience better visibility for views and more comfortable hiking conditions. Due to its elevation, Crimea Pass and other higher passes can be challenging to traverse and are often closed in winter due to snow and ice, making winter hiking suitable only for experienced individuals with proper gear.
Yes, several passes, like Bwlch Main Ridge, feature exposed sections and steep slopes, which can be daunting in inclement weather or for those not used to such conditions. Weather in Snowdonia can change rapidly, so always be prepared for rain, wind, and colder temperatures, even in summer. Some passes, particularly Crimea Pass, can be closed in winter due to snow. Always check local conditions before heading out.
Bwlch Glas Pass is a significant meeting point on Yr Wyddfa (Snowdon). It's where the Pyg and Miners' Tracks converge with the Snowdon Ranger, Llanberis Path, and routes from Crib Goch and Garnedd Ugain on the summit ridge. A finger stone marks this crucial junction, making it particularly helpful for navigation, especially in poor visibility.
Yes, parking is available at some key mountain passes. Pen-y-Pass, for instance, is a well-known parking area and trailhead. However, it's important to note that parking at popular spots like Pen-y-Pass often requires online booking and payment, especially during peak seasons. Always check current parking regulations and availability before your visit, as signal can be poor on site.
Cnicht Summit is highly popular due to its distinctive, fin-like peak, earning it the nickname 'Welsh Matterhorn.' It offers fantastic, less crowded climbing opportunities compared to other major peaks and provides wonderful views across the Moelwynion range and towards the Lleyn Peninsula. It's considered the best of the Moelwynion range for its shapely attractiveness and rewarding ascent.
While Crimea Pass is directly associated with Ffestiniog, other iconic passes within Snowdonia National Park are accessible and worth exploring. These include Llanberis Pass (Pen-y-Pass), famous for routes up Snowdon; Nant Ffrancon, offering stunning views of Tryfan; and Bwlch Tryfan, a crossroads for several challenging trails. These passes collectively showcase the dramatic beauty of the region.
