Calculate the time using Naismith’s Rule and factor in your own pace.

Start and Finish: Rhyd Ddu to Nebo

Facilities:

VERY decent pub and tearoom in the village, WC at car park.

Hazards:

There are plenty of hazards to be found on this walk with exposre and steep ground on most of the walk. While some of it is proper scrambling,  most of it being traversing steep ground. Serious proposition in winter conditions! Main steep sections are the crest of Drws y Coed, the “Hiatus” between Tal y Mignedd and Trum y Ddysgl and the steep descent to Bwlch Dros-bern.

Remember that we cannot outline every single hazard on a walk – it’s up to you to be safe and competent. Read up on Mountain Safety , Navigation and what equipment you’ll need.

Public Transport:

Rhyd Ddu is served by Snowdon Sherpa buses, but you’ll need to ring a taxi in order to return to Rhyd Ddu. We recommend M&R Taxis – our local firm and nothing to do with our M and R! Alternatively, base yourself in Caernarfon or Porthmadog, as you can use the buses to get to the start and there’s a bus service back from Nebo.

Traveline for UK Public Transport
Parking and Post Code for Sat Nav (where applicable): Rhyd Ddu - LL54 6TN, Nebo - LL54 6RT

In Rhyd Ddu there’s a car park at the start of the Rhyd Ddu path. If using two cars, then you can park at the Cwm Dulyn road near Nebo which can be found at SH483 500 or here on Google Maps. Parking in Nebo isn’t practical.

The Nantlle Ridge Linear Traverse Details

The Nantlle Ridge in Snowdonia can be walked as a circular route from Rhyd Ddu, but it’s much more satisfying to walk the Nantlle Ridge Linear route. You’ll need to use two cars or book a taxi if you need to return to the start. Alternatively, you can base yourself in Caernarfon or Porthmadog and use a bus either end. Either way, the Nantlle Ridge is one of the best ridge walks in Snowdonia. Some sections are a Grade 1 Scramble, but only just. There’s nothing that should worry a seasoned hill walker with a head for heights as there are a few sections with some exposure.

The Full Nantlle Ridge Traverse Route Description

The walk, like always for the Nantlle Ridge, starts from Rhyd Ddu car park. On the opposite side of the road there’s a gate for the Lon Gwyrfai that you need to pass through, and then follow a path along the boggy field. This takes you towards a cottage in trees, continue to follow the track and the signs to arrive back at the main road.

You may ponder why you’re now on the road. Bear left and enter the next field to continue on the footpath. Shortly, the path takes an obvious uphill right, which is unmistakably the way up Y Garn. This is yet another Garn, and may often be called Y Garn II in lists to distinguish it from Y Garn in the Glyderau (there’s a Garn III in the Rhinogydd). Thinking about the other hills named Y Garn might put you off the slog ahead, or maybe not.

In an hour, or a little more, the path eases off and the worst is behind you. Right takes you to the summit of Y Garn, which isn’t more than the end of the ridge, but is a fine viewpoint. You’ll also more than likely feel like you’ve deserved a break after all that steep climbing too, and you’ve even got the choice of two summit shelters to do so.

Route finding on this section of the Nantlle Ridge isn’t hard, at least not until you arrive at Craig Cwm Silyn. Follow the ridge. Mynydd Drws y Coed is the highlight, being a grade 0.5 scramble, with a couple of exposed walking sections. But the scrambling is over all too soon, so make sure you take your time and wander off to your right to peer into the cwm far below Craig Marchnad.

The summit is almost a disappointment, being so grassy – but it makes another decent spot for a break. That’s the problem with the Nantlle Ridge, so many summits to climb and it feels downright rude not to stop on each one and give the summit the time it deserves. The next ones upon you soon. Steeply down, then steeply up to Trum y Ddysgl, where there are invariably people stopping for their third lunch of the day. The flat, grassy summit being easy on the feet. You can descend to Rhyd Ddu from here (see other route), but it’s much better to walk the lot if you can manage it. Feels complete.

Down again, through the interesting col between Tal y Mignedd and Trum y Ddysgl, with it’s notch to negotiate and much more exposure than you’d expect. Tal y Mignedd is the one with the obelisk. So you can’t miss it. It’s also easily attained, and there’s a wall to lead you most of the way up.

Make the most of the grass, the walk roughens up again soon. First the steep, loose descent to Bwlch Dros Bern. Reaching the col is a relief, and today i was meant to camp here. It was far too windy, and i decided i wanted to ascend all the summits today. Last year i’d have descended to a campsite at this point, it shows that the fitness does *Eventually* build. I did find a nice, sheltered spot in the bwlch though, but the lack of water nearby meant i had to plod on. The climb of Craig Cwm Silyn can be difficult to find, but if you know to contour right for a short while you’ll not go far wrong. Only near the top does the path vanish in the rocks, but perseverance should see you on top.

You can relax now. That was the last real climb you’ll do on the Nantlle Ridge. After a 5th break on the top, or if you’re feeling picky there’s two tops near each other so possibly 6th, the walk across to Garnedd Goch is along a wide, stony ridge. There’s a faint path, and this would be easy to miss in mist. Fortunately, there’s a stone wall that can be used as a handrail about half way across. This can be followed all the way to the top of Garnedd Goch, which is really an insignificant bump on the ridge, but being on the edge gives it views down across Pen Llyn.

The wall dips steeply down the slope, I found that by following the side opposite the summit was best idea. The ground is rougher and heathery now, the lack of clear paths a testament to the few walkers that make it this far. Most have already scurried back to their cars in Rhyd Ddu. You can plod on, and i was surprised to bump into a few people at this far end of the ridge. What I’d hoped to bump into was a river, so I descended a couple of hundred metres to a river – that was dry! I couldn’t descend much further without entering farmland, and the ground around me was too heathery to camp in, so I reascended and aimed for the river shown at Bwlch Cwmdulyn.

This is a clear notch in the walk, but there wasn’t any water. There was no way I was re-tracing my footsteps to Bwlch Dros Bern now, so I decided that I’d had a good day’s walk and that’d be it. Crossing from Bwlch Cwmdulyn to Mynydd Graig Goch was easy and flat, but with some very boggy areas – but mainly dried up today so were easily avoided. You need some decent compass skills in mist to cross the plateau, but the wall that crosses the summit means you can’t overshoot without hitting it.

Mynydd Graig Goch is a remote outpost of Snowdonia, sharing more with Bwlch Mawr on the opposite side of the wide Dwyfach valley than it does with the walk you started. Now that would be an interesting continuation to the walk. The summit is bouldery, and shelter can be found. The eagle eyed might spot the little shelters built below the summit, in the rocks, probably for shepherds in the past – I was hurrying too much today to investigate.

Nantlle Ridge Linear Traverse

I was relaxing now, being the end of the walk and it all being downhill. I’d not reckoned on the Great Wall of Nebo that blocked my progress. The stone stile to cross is well hidden, but can be found by following the stone wall a short distance to the NE. It isn’t the easiest to cross either!

Once this was passed, then it really was downhill. No path, or an intermittent one at best, that becomes clear near the bottom, but there are poles you can follow to the wall. Again, in mist you’d be aiming for the stone wall ahead before turning right and downhill to Llyn Dulyn – not to be confused with Dulyn in the Carneddau. It was a lovely spot, and a couple of elderly gents were here – much the worse for wear – making the most of the setting. They told me that the flag on the gate was theirs and i wasn’t to take it.Nantlle Ridge Linear Traverse

A track leads down to Nebo from here, or just a little further to Llanllyfni where there are many bus services (but tonight it was taxi time!)
