Walk Route Description

This lengthy circuit of the southern Rhinogs offers a great day in the hills. In contrast to the northern peaks of the range, which are rugged and rocky, this hike takes in the smoother but no less interesting peaks of Diffwys and Y Llethr.

The start of this Snowdonia walk is a small car park (grid ref SH603230) at the end of the lane leading to Gors y Gedol Hall from the A496 Barmouth to Harlech road just north of the village of Tal-y-bont. After parking go through the gate and follow the track heading east. This track, after a pair of right angled bends, reaches open country with the rounded shape of Moelfre on your left. Stay with the main track, ignoring the right fork that leads down to Pont Scethin. An indistinct path forks left (grid ref. 635242) and this heads up to the col on the eastern side of Moelfre.
You will soon pick up a more obvious path and this leads up to a wall which is followed for some way as it climbs steadily towards the first objective - the rounded summit of Y Llethr. As you climb the views improve rapidly and reaching a junction of walls turn left to climb steeply northwards to the cairn that marks the summit. For the best views continue over the top towards Rhinog Fach and you will find some rocks that offer grandstand views over Llyn Hywel to the rugged northern Rhinogs.
Retrace your steps past the summit and drop down to the wall junction mentioned above. With the wall on your left head roughly south along the top of Crib-y-rhiw where steep crags plunge to the wide valley below. The undulating path meanders through pleasant rocky outcrops before climbing more seriously to the summit of Diffwys.
If you are lucky and the weather is good then you will be rewarded with a superb view across the Mawddach estuary to Cadair Idris with the rarely visited summit of Y Garn also in view. Stay with the wall as you head south from the trig point turning west and staying with the wall over smooth upland to an intermediate spot height of 642 metres. Continue on the ridge path crossing a wall to reach a path that heads north down towards Pont Scethin. In bad visibility this may be hard to find. However at the point where the descending path meets the ridge path, there is a gate and a stile in the wall, and a cairn marking the descent about 10 yards to the right of the path.
This path was apparently the old Dolgellau to Harlech road although it is hard to imagine a coach and horses crossing this landscape in bad weather. The descent to Pont Scethin is straightforward and after crossing this old bridge you are soon back on the track you used for the outward sector of this walk. All that remains is steady plod back to the car park.
As with many mountain hikes this is one to save for fine weather. The views are without doubt some of the best in Southern Snowdonia with a variety of landscape seen on few walks. In addition there are many areas of water which add interest to the views.
