Llyn Morwynion & Y Garnedd

Llyn Morwynion & Y Garnedd

A short walk in wild country to the east of Ffestiniog.

This walk is a little over 3 miles in length with around 700 ft of ascent. It takes in the small dammed lake ‘Llyn Morwynion’ and the peak of Y Garnedd. Most of the walk is across open-access land.

Parking is available (currently free) just off the B4391 near the viewpoint for Rhaeadr y Cwm. It is definitely worth taking a small diversion to view this cascade of falls. Some of this area can be very boggy, so do be prepared.

Leave the parking and walk west along the B road for a short distance before crossing a gate on the right and following the water company track to the dam of Llyn Morwynion. Proceed around the head of the lake on a small pathway. As you now walk northerly along the western edge of the lake, gradually climb to the higher ground away from the lake. The views behind you are extensive, across moorland towards Arenig Fawr.

Now turn north easterly along this small ridge towards Y Garnedd. Carefully choose a route across the marshy ground at the base of Y Garnedd before climbing up between rocky outcrops to the small summit. We found some colourful sheep amongst these rocks ..

Upon reaching the summit, perhaps pause to enjoy the views that continue to be panoramic across this upland region; including a view north to Llyn Mawr Gamallt & her crags.

We now descended towards the south-east. Care must be taken here to avoid the loose rock / cliff falls by the old quarry. Skirt the southern edge of the quarry and zig-zag down to its access road. Follow this track for a short distance until it turns sharply to the left. It is possible to follow this track back to the road and walk along the road back to your car – this would avoid the boggy crossing. We however, turned off the track to head SW across the peat bog back to the northern edge of Llyn Morwynion. Care must be taken to select a suitable route (especially in winter). Upon reaching the lake, turn left, through a small gateway and follow the narrow path along its edge back towards the dam. This is a very peaceful upland lake, slightly sheltered from the wind on the day of our walk (see post header picture).

As we crossed this tufty marsh grass area, a well camouflaged short-eared owl took off just in front of me. There was no time for a quality photo but I did get this quick snap of him.

To return to the car park, either retrace your steps along the dam access road or take the indistinct footpaths across the rough grassland, as indicated on the outline guide map below.

Do take a few minutes to enjoy the nearby waterfall viewpoint, or perhaps follow the footpath down closer to the river cascades.
