Carneddau Circular - Pen yr Olwen, Carnedd Dafydd & Carnedd Llewelyn

Carneddau Circular – Pen yr Olwen, Carnedd Dafydd & Carnedd Llewelyn

Date/Time: 28/07/2020 - 31/12/2021, 8:00 am - 5:00 pm Location: Ogwen Valley, Ogwen valley

The Carneddau range is around 70 square miles, wild and rugged, with remote mountain tops where on a good day we will see no-one else!

The highest point in the Carneddau, Carnedd Llewelyn at 1064m in height is only 21m shy of the highest peak in Wales, Yr Wyddfa (Snowdon) at 1085m, but it rarely sees any visitors in comparison.

It is a tough but immensely rewarding circular route that also takes in the peaks of Pen yr Olwen at 978m height and Carnedd Dafydd at 1044m height.

This Carneddau walk will hopefully leave you exhausted (in a good way!) but will live long in the memory!

Note: A minimum of 4 people is required for a walk to take place


Carneddau Ascent

Our walk starts just past the east end of Llyn Ogwen, which was created by a glacier that passed though the Ogwen valley 10,000 years ago.

A steep start to our climb as we gain 300m in the first 1.5km to reach the stunning Ffynnon Loer. We will take a short break here before continuing our ascent.

The next 1km involves some easy walking but also includes the classic ‘chimney’ route, a short section where we will need to use our hands as well as our feet which makes it a truly thrilling adventure! Once through the chimney it is a straight forward walk around the ridge to reach our first summit Pen yr Olwen (Head of the White Slope) at 978m in height.

We continue to traverse around the top of Cwm Lloer for around 2km, droping slightly at first, before gaining another 100m in height to summit Carnedd Dafydd (David’s Cairn) at 1044m in height.

The walk continues east along the top of the Ysgolion Duon (Black Ladders) cliffs and offers great views looking over to the Snowdon Range, Tryfan and the Gyderau.

We then reach Bwlch Cyfryw – Drum above Cwm Llugwy before we take the final 130m to reach our final summit Carnedd Llewelyn (Llewelyn’s Cairn) at 1064m in height.

Carneddau Descent

After a rest the excitement continues as we traverse below the crags of Craig yr Isfa and above Bwlch Eryl Farchog to reach Y Braich, a long grassy wide ridge that leads us on a easy path back down towards the roadside.

From here we cross over the road and return to the start via Gwern Gof Isaf and Uchaf campsites with easy walking.
