Complete guide to hiking the Nantlle Ridge — Snowdonia’s finest ridge walk

Across the road from Yr Wyddfa (Snowdon) yet seemingly invisible to the outside world, the thrill ride of Nantlle Ridge will forever seem your own incredible discovery.

If ever there was an example of the importance of keeping an open mind when it comes to walking in the mountains, the Nantlle Ridge is it.

Lacking a single star name, not one of its summits poking above the 750m contour, and without even the courtesy to lay itself out in the shape of a convenient horseshoe, the Nantlle Ridge eschews cheap shots at your attention, yet is one of the most substantial mountain achievements in the country.

Next to magnificent Yr Wyddfa anything would struggle for the limelight of course, but under its multiple veils of obscurity lies an absolute belter of a ridge walk.

To spend a day traversing it is to immerse yourself deeply in the glory of wildest Snowdonia as if before the coach parties ever discovered it, and convince yourself not only that Eryri is one of the world’s great libraries of adventure, but a groaning shelf of inexplicably under-thumbed thrillers.

It’s a scrambly adventure for sure, but its hands-on sections are relatively brief Grade 1 stuff – enjoyably absorbing rather than really alarming, and in the case of the trickiest one, on Craig Cwm Silyn, avoidable should you wish.

You can nibble Nantlle as a circular walk from Rhyd-ddu, abbreviating the ridge at the obelisk-topped Mynydd Tal-y-mignedd, if limited by time, weather or transport.

But a complete traverse taking in Y Garn (633m), Mynydd Drws-y-coed (695m), Trum y Ddysgl (709m), Mynydd Tal-y-mignedd (653m), Craig cwm Silyn (734m), Garnedd Goch (700m) and perhaps even Mynydd Graig Goch (610m) should be on your bucket list.

You’ll need a second car parked near Llanllyfni at (grid reference SH495510), but it’s worth the hassle for one of the most satisfying tasting menus of Grade 1 scrambling, mountain atmosphere and lofty spectacle imaginable. Once you’ve wolfed it, you won’t shut up about it – for all that anyone will know what you’re talking about.

How difficult is the Nantlle Ridge?

If you’re an experienced mountain walker then this isn’t a route that should hold too many difficuklties. It isn’t too long at just over 14km and has a relatively modest height gain at 1005m. There are a couple of scrambling sections with mild exposure but nothing to rival a ridge like Crib Goch.

Rather than being sharp and scary, many people describe the Nantlle Ridge as 'Snowdonia’s Best Ridge Walk', which feels like a good summary to us.

What scramble grade is the Nantlle Ridge?

Officially there are some sections of Grade 1 scrambling, but they only make up very short sections of the ridge. For the most part it is glorious and undulating hillwalking.

Where’s the best place to start from?

The transportation logistics are the trickiest part of walking the Nantlle Ridge. Most people start from Rhyd Ddu and head west to the end point of the ridge near the village Llanllyfni (which is the route described below).

Public transport is limited to say the least, so you'll be faced with an expensive taxi ride or a long walk back unless you leave a second car at the end.

Where’s the best place to stay?

The Snowdon Ranger YHA is very good, as is the legendary Pen-y-Pass YHA a little further away. We also rate the Cwellyn Arms in Rhyd-Ddu with its wide range of accommodation, and the excellent Llyn Gwynant Campsite. For good local deals near the start of this route, check out Booking.com

What gear do I need for this route?

This is a proper mountain route, so we'd recommend investing in good and robust kit. Walking boots are an obvious essential, as is a good hiking daypack, a reliable waterproof jacket (essential in north Wales!), an insulating layer, and a pair of quick-drying walking trousers with some packable waterproof overtrousers in your bag.
