Cnicht Mountain Circular Walk (and video guide)

An Autumnal Walk up Cnicht, Eryri (Snowdonia)

Cnicht ‘The Welsh Matterhorn’ has been on my list for a long time, it’s such an interesting walk with varied terrain and some fabulous views out to sea and across Snowdonia. This circuar route of Cnicht starts from Gelli Iago, an alternative to starting from Croesor which is much busier.

(The photos are from two trips, I had to go back to get the views after a cloudy summit on my first visit!)

How easy is Cnicht Mountain?

The walk shown took around 4 1/2 hrs. It’s a fairly straightforward path to follow although there are opportunities to get lost if visibility is poor so make sure you check the weather and also that a member of your party can read a map and use a compass. There is no exposure and a tiny amount of scrambling on the top. You’ll need a decent level of fitness.

Where to park to walk up Cnicht?

Parking for Cnicht at Gelli Iago

Rather than starting from Croesor, we parked in a lay-by that fitted around 10 or so cars. If you put Gelli Iago / Nantmor Mountain Centre into Google Maps or your Sat Nav, you’ll see the layby on the left-hand side as you’re approaching from the north. The path starts just a short walk down the road.

As you can see the parking for Croesor is further South, but there are plenty of nice loops you could start from there too.

Go through this gate and to the left of the buildings. Keep the stream to your left as you find the obvious path behind the buildings to the right.

There are a few routes to choose from but we chose a simple loop that returned us just a little way up the road from the layby. So not too long on the road.

The path starts really gently, crossing a stream and then quite gently winding up the hill

After passing this little lake on the left we needed to keep an eye out for where best to cut across to pick up the Cambrian Way and then head up to the summit. If we stuck to the path we would lose quite a bit of height.

There wasn’t a clear path on the ground so we just picked our way across some roughish terrain.

You can see the kind of terrain in this pic looking down on the rest of my party.

On my second visit I chose to walk further down to a fenceline before cutting the corner to get up onto the Cambrian way and join all the people walking up from Croesor. You can just keep walking and join the Cambrian way further down if you don’t want to leave the official path.

You can use this fence as a guide to get you to the top, it is a steep path and quite boggy!

The top is rocky, we lost all visibility as we approached the summit but the path is clear. The route we took down needed a little concentration to make sure you didn’t lose the path. Take the left just as you pass Llyn yr Adar

My brother, my 8yr old nephew, and Iska their Bedlington Whippet. The path is narrow as you climb up through the rocks but clear and there is no exposure. An exciting route for challenging younger kids!
The rocky path to the top – sadly no views for us this time so I will definitely be back (edit – I did go back and I got the views!)

llyn y biswail
After the summit ridge section, you’ll find the Cambrian way continues on. Stay on this path. Pass Llyn y Biswail to your left until you reach the far end of Llyn yr Adar (it has a little island). When you reach it, make a left. Follow the path as you start descending.

This is Llyn Yr Adar, you’ll see the main Cambrian Way carries on to the right higher up, you will cut across here aiming to take a left around Llyn yr Adar until you pick back up a faint path.
Hilary, Ziggy and Llyn Ilagi
With Ziggy my Coltriever, behind me you can see Llyn Lagi (if you look on the map you’ll see it’s possibly the roundest lake in Wales!) and further in the distance you can just see Llynau Cerrig-y-myllt. I plan to walk up to these little lakes in the summer, they look beautiful.

There are lots of Holly trees on the route down back to the road. It’s an absolutely stunning landscape.

  2. I did this walk yesterday, thank you for the route! I can really recommend doing this walk in winter, timing the last section from the lakes back to the car to coincide with golden hour. The light coming off Yr Aran, Yr Wyddfa and Y Lliwedd was absolutely spectacular at this time of day (about 3:30 – 4:00pm in January), especially with a very light dusting of snow on the tops. I started off in quite grey conditions, the summit was covered in cloud, though I did get views most of the way up, and stopped for lunch while I could still see! The second half of the walk was extremely boggy and I was glad of my hiking poles and waterproof socks! I’m definitely going to do this walk again on a clear day.

    1. Oh that sounds like you had a great day, glad you found this route useful – it’s definitely boggy in areas!!! The lakes are stunning, Ziggy played catching stones on the little pebbly beach area for ages

  3. […] The views from Cnicht […]

  4. Llynnau Cerrig y Myllt are beautiful, I’ve wild camped there several times . Llyn y Arddu nearby is also a beautiful spot and the view of Cnicht from Yr Arddu is pretty special

    1. Ah thanks Sharon 🙂
