Mynydd Graig Goch

A circular walk taking in the summit of Mynydd Graig Goch is a glorious, short, mountain blast. We think its perfect for an evening walk. The view from the top look out onto the Llyn, Ynys Mon and The Irish Sea, sunsets are impressive – don’t forget a headtorch for the walk down.


You can see the whole, wonderful, route from the car park. Look to the mountains, on your left you’ll see Garnedd Goch and the start of Nantlle Ridge, over to the right is the broad summit of Mynydd Graig Goch.


There’s a wooden footbridge next to the carpark, cross that bridge and cross the ladder stile over the drystone wall, follow the reasonably worn in track almost due East. The track starts to climb straight away and continues to climb towards Bwlch Cwmdulyn until you reach a tumble down section of the dry stone wall.

Drystone Wall

Here, on a another day, you might turn sharp left, before crossing the drystone wall to climb Garnedd Goch and start the Nantlle Ridge. But, today, we’re going to cross that tumble down wall and continue to follow the track round through Bwlch Cwmdulyn and up onto the broad plateau of Mynydd Graig Goch.

The track is well work in and is hard to deviate from, you’ll see the pronounced and jagged higher ground of the mountain ahead of you. The worn in track meets the steeper, craggier ground in the middle of its mass.

Higher Ground

Once you reach the higher ground turn right (North East) and, carefully, find your way across the broken stone top towards the tall drystone wall that is crossed by another ladder stile right next to the summit ‘flag pole’.


Have a snack on the summit, take in the glorious views, then start to descend, the route down starts with a uneven, rocky section but soon reaches a worn in path that heads down hill and North East, some wooden posts also mark the line of the path.

As you get lower the path will narrow between heather on both sides then open up onto a stepper decent over a sheep cropped swathe. There’s a great boulder to stop for a minute and think about life.


From the mighty boulder you can see the rest of the route as it snakes down hill, heading North towards the lake. There’s a fence/ stile to navigate but we’ve never had a problem getting the dogs over.

The walk finishes parallel with the lake as the track flattens over the last few hundred meters before the car park. We have heard that Llyn Cwm Dulyn is an incredible place for a swim, especially on a summers evening but we can’t condone that because there are big signs everywhere that say “DON’T YOU DARE SWIM HERE”.

That’s it – all done.
