Welsh 3 Peaks Challenge

Welsh 3 Peaks Challenge

Date/Time: 04/06/2022 - 30/09/2022, 8:00 am Location: Snowdon, Llanberis

4th June 2022

27th August 2022

Welsh 3 Peaks – Snowdon 1085m, Cadair Idris 893m and Pen-y-Fan 886m in 24 hours!

29km/18miles of walking with 2606m/8550ft of ascent makes this a tough but fantastically rewarding challenge.

The Welsh 3 Peaks is a team challenge and not designed to be an individual competitive event.

You will be part of a small bespoke group of 12 people maximum with 2 experienced and qualified mountain leaders and an Event/Logistics Manager on the ground to support you.

After completing all three mountains we will celebrate our success at the legendary Moel Siabod Cafe with a hearty breakfast!



We will summit the mountains in the following order: Snowdon – Cadair Idris – Pen y Fan

From our starting point in Llanberis we will transfer to Pen-y-Pass and begin our accent of Snowdon 1085m via the Pyg track, with our decent via the Miners.

After Snowdon we drive to Dol Idris, Minffordd to begin our climb of Cadair Idris 893m. After completing Cadair Idris we then transfer to Storey Arms, Brecon. Our final climb then begins to summit Pen-y-Fan 886m in the dark.


We encourage everyone in the team to help and support each other at all times to give the whole group the very best chance to complete the challenge.

The challenge is both a physical and mental one that requires a good level of fitness but also very importantly the willingness/ability to work as part of a team to succeed in reaching all 3 summits.

Whilst this is a 24-hour challenge, it is very important to say that we cannot compromise on our safety procedures, risk assessments and standards to make the 24-hour time limit if we start to fall behind on time.

It is a group challenge therefore the group will complete each mountain together and the pace will therefore be managed accordingly for safety.


Accommodation is provided on the Friday night so that everyone can get to meet each other. Also you will get to meet your Breese Adventures Event Manager (and hopefully the mountain leaders). A full kit check will be done with an event briefing covering what will happen over the 24 hours.

Welsh 3 Peaks Mountains & Routes

Snowdon Pyg Track

Distance:  7.4 Miles / 12.3 Km

Time: 4-6 Hours

Start Height: 360m

Finish Height: 1085m


As the path leaves Pen y Pass you will climb steeply over rough and rocky terrain for 1 mile (1.6km) gaining just over 210m in height, until we arrive at Bwlch y Moch (pass of the pigs or the crag of the pass of the pigs).

We contour round the ridge leading up to Crib Goch the dramatic peak of Snowdon comes into full view with the dark imposing crags of Clogwyn y Garnedd and Bwlch y Saethau (translated Pass of the Arrows).

At just under 2.5 miles (4.1km) we reach a standing stone at 735m in height that is the intersection of the Pyg and Miners track (our decent route). The terrain under foot gets a little trickier at times as we ascend steeply up via the zig zags to Bwlch Glas.

From here it is just under 0.4 miles (0.6km) to the summit of Snowdon (Yr Wyddfa), the highest mountain in Wales at 1085m!


Our descent begins by retracing our steps to Bwlch Glas then steeply down to the intersect of the Pyg and Miners Track and at this point we do not continue on the Pyg track, instead we again head steeply downhill on rocky terrain until we reach Llyn Glaslyn (blue lake) at around 600m in height.

From here it is a very straight forward but beautiful walk back along the track as we descend 240m in height over the next 3 miles (5km) via the old Brittania copper mine workings and buildings down to Pen y Pass.

Cadair Idris Minffordd Path

Distance:  5.6 Miles / 9 Km

Time: 4-6 Hours

Start Height: 102m

Finish Height: 893m


The route follows the spectacular Minfforrd path, steeply at first though forestry before emerging beneath Cwm Cau where after a little while we reach the beautiful and tranquil Llyn Cau. We will rest here for a while and absorb the magnificent surroundings and talk about the giant who if you believe folklore once lived here.

After our break we again climb steeply up steps for a short while to reach the rim of the Cwm before traversing around via Craig Cau (rockwall) to reach the summit at 893m height. If the weather is bad we can take cover in the summit shelter.

The views from the top are breath-taking, looking out over the Mawddach Estuary, most of Wales, from the Llŷn peninsula in the north-west to the Brecon Beacons in the south-east.

We continue after our lunch stop heading east over a boulder field towards the smaller summit of Mynnedd Moel at 863m height (we may as well bag this too!).


Our return is via a steep grassy path south to pick up the Minfforrd path once again for the final 0.5km to the start point.

Pen-y-Fan via Beacons Way

Distance:  4.9 Miles / 7.8 Km

Time: 3-4 Hours

Start Height: 431m

Finish Height: 886m


We begin our ascent of Pen-y-Fan from the Pont ar Daf National Trust Car Park just south east of the Storey Arms Outdoor Centre.

The walk in daylight is a very straightforward one as the paths are well maintained and very wide in places. However, for our Welsh 3 Peaks summit attempt we are walking in the dark so care and attention is needed at all times especially around the summit area and on the descent around Corn Ddu.

Crossing the Pont ar Daf and picking up the Beacons Way national trail we wind our way up past waterfalls climbing quite steeply before we arrive at Blwch Duwynt which is at 2.5km into our route.

By the time we reach the Bwlch most of the height gain has been achieved as we are now at 814m with only 72m left to climb!

The final 1km of walking is relatively straightforward as we contour around the cliff face of Corn Ddu (Black Horn) to reach the summit of Pen-y-Fan 886m with its well-preserved Bronze aged cairn.


Our descent begins by retracing our steps for 0.5km to an intersection of paths just below Corn Ddu. Instead of continuing down our ascent route we take the path to the right below the cliff face of Craig Cwm Llwch.

After approximately 300m we pick up our descent route heading south west for 1.5km until we cross Blaen Taf Fawr. We then have a short uphill section before our final 1km of descent down behind the Storey Arms.

Once back we pick up the path that runs parallel with the road for our final 1km walk back to the starting point.
