All the Walks up Cader Idris Introduction

Cader Idris or Cadair Idris, is regarded among Wales’s best mountains. It is found between the town of Dolgellau and Abermaw (Barmouth) on the coast, with views up from the Mawddach Estuary dominated by this impressive South Eryri (Snowdonia) mountain.

Sitting outside the popular ranges in the north of the Parc Cenedlaethol Eryri (Snowdonia National Park), you would imagine Cader Idris to be a ‘quieter’ option in comparison. But don’t be fooled, with it having numerous approach options, spectacular views, being part of the Cader Idris Special Site of Scientific Interest (SSSI), Special Area of Conservation (SAC), and boasting to be part of the Welsh Three Peak Challenge, it is rightly one of the stars of Eryri(Snowdonia), if not Wales as a whole.

Interestingly the summit is known as Penygadair, which means top of the chair. On a clear day you can enjoy views up towards the north of Eryri (Snowdonia), as well as out to the coast with the Mawddach Estuary taking your eye out to Abermaw (Barmouth) and beyond.

Why is it called Cader Idris – why not Cadair – don’t get us started…

Cader Idris translates as “chair of Idris”, and many believe it origins come from a character in Welsh mythology called Idris Gawr or “Idris the giant”. Who would use the mountain’s geological features as a massive natural armchair to look up at the stars. Some say it may owe it’s name to a previous prince of Meirionnydd Idris ap Gwyddno, with the real origins somewhere in between perhaps?

What pubs are good for Cader Idris?

We recommend the Llyn Gwernan Hotel and the Minffordd Hotel as they are both convenient to the path starts. For Llanfihangel y Pennant, you’ll need to go to the Railway in Abergynolwyn.  However, we suggest you check the individual routes for further information on local facilities and whether they are still open in these difficult times or operating under reduced hours..

Cader Idris Minffordd Path

Height Gained – 930 metres,  Distance – 5 km, Time –3 hours

The Minffordd Path is regarded as one of the best route up Cader Idris. With an initial approach up a steep gorge, views across it’s own mountain tarn, Llyn Cau and a ridge walk over Craig Cwm Amarch to complete the walk to the summit – everything you need for a day out in the mountains.

Note that there is an alternative that cuts out Craig Cwm Amarch and ascends a scree gully at the far end of Llyn Cau to Crag Cau, this is loose and we’d suggest the official route unless you have a thing for steep scree paths – which we certainly do not!

Pony Path

Height Gained – 740 metres,  Distance – 4.6 km, Time –3 hours

If the Minffordd Path is the most dramatic, then the Pony Path is probably the most popular. It’s certainly the most straightforward route up as there are no intermediate summits to climb as with the Minfordd Path or a scree chute to navigate as with the Fox’s Path.

Fox’s Path

Height Gained – 710 metres,  Distance –4.5 km, Time – 3 hours

The Fox’s Path is the most notorious path up Cader Idris owing to a section of treacherous scree on the final section. In Welsh it is known as Llwybr Madyn, which is a rarely used term for a fox, which contradicts the alternative reasoning for the name – that it was named after the founder of the Quakers – George Fox. This article from 1820 mentions no source for the name – Ascent of Cader Idris in 1820 and calls the path Llwybr Madyn or later in the article as the “Fox’s Path” – with the emphasis given by the author suggestive of a translation from the Welsh. The route itself is an interesting approach, with views more open than the Minffordd Path, but the steep scree path from Llyn y Gadair to the summit lets this route down.

Llanfihangel y pennant Path

Height Gained – 870 metres,  Distance – 8 km, Time –4 hours

From the notorious to the laborious – with the Llanfihangel y Pennant path being the longest of the ‘official’ approaches at 8.5km in length. Despite the length, it’s steadier than the Pony Path with which it shares the final couple of kms to the summit.

Cader Idris via Mynydd Pencoed from Llanfihangel y pennant

Height Gained – 970 metres,  Distance – 7.5 km, Time –3 hours

An alternative approach from Llanfihangel-y-pennant takes the route up Mynydd Pencoed and Craig Cwm Amarch to join the Minffordd Path for the final section. This is one for those looking for a pathless and quiet route.


Cader Idris Via Gau Graig from Bwlch Llyn Bach

Height Gained – 720 metres,  Distance – 6 km, Time – 3 hours

You can start this route from the car park at the top of Bwlch Llyn Bach and follow the Cambrian Way up to the plateau at Gau Graig. This is a seldom frequented route, but a pleasant enough walk once you attain the summit of Gau Graig. The views of Cader Idris’ northern cragd fro this approach are one of the highlights. 

There is a bridleway that you can follow to join this route up with the Minffordd paths, but this only joins partially and involves two sections of dangerous road walking which is not recommended. That is unfortunate as coupling this route with the Minffordd Path would make this one of the best days out on Cader Idris

Cader Idris From Dolgellau

Height Gained – 980 metres,  Distance – 9 km, Time –4 hours

This is the longest route up Cader Idris at 9km and is basically a longer approach to the Gau Graig route. Starting from the historic town, it follows country lanes before setting off up a quiet ridge to Gau Graig and across the wide ridge to the summit of Cader Idris. You can return to Dolgellau by descending the Pony Path and walking back on country lanes..

Cader Idris via Mynydd Moel

Height Gained – 850 metres,  Distance – 5 km, Time –2.5 hours

Again – we’re back at Minffordd with an another alternative route. This walk follows the Minffordd Path for a short distance before heading up the opposite side of Cwm Cau to the summit of Mynydd Moel. The ascent is steeper and the path is patchy in places in comparison to the Minffordd Path, but is still a satisfying route. It’s often used as a descent for those ascending via the Minffordd Path.

Cader Idris via Tyrrau Mawr

Height Gained – 720 metres,  Distance – 6.6 km, Time –2.5 hours

Our final approach is a long route that can be started from numerous points along the Ffordd Ddu, with the distance above given from Hafotty-fach on that road and along the Cambrian Way. You would be more likely to start from Cregennen or even the Ty Nant car park that the Pony Path starts from.  Follow the link above for a longer version that includes the bonus summits of Craig-y-llyn and Braich Ddu.
