Do not walk if you are feeling unwell. Carry your own hand sanitiser. In case of an emergency ensure you have with you a face mask and first aid pack.
Inevitably, the route will go through gates and over stiles that other people will have touched. It may have narrow sections that mean you will be passing close to other people.

A fine mountain walk on the northern Glyderau with stunning views and some impressive situations.

We begin our walk at Ogwyn Cottage following the easy, well-constructed track to Llyn Idwal and along the east shore to beneath the Idwal slabs. The path gradually steepens and becomes progressively rockier with occasional easy scrambling as we make our way to the improbable exit through the back wall of cliffs on to easy ground approaching Llyn y Cwn where we will stop for a well-earned coffee.

We continue north up easier slopes to the summit of Y Garn, our first peak and high point for the day. Continuing north on grassy paths, if conditions are clear and calm, we can visit the additional peak and splendid view point of Foel-Goch. Whether crossing or bypassing Foel-Goch, we continue on and up grass slopes to Mynydd Perfedd with its panoramic views of the Welsh 3000’s and the Ogwyn valley. An easy walk out to the rocky top of Carnedd y Filiast gives fine views down the Atlantic slabs to Nant Ffrancon and across to Anglesey.

Retracing our steps to the foot of Mynydd Perfedd, we begin our descent into the grassy bowl of Cwm Baul to pick up a rough path below the cliffs of Foel-Goch. We follow this round and into the impressive amphitheatre of Cwm-coch. The path narrows and becomes a little more exposed as it contours around the corner below Creigiau Gleision before traversing “The Mushroom Garden” (no mushrooms, not much garden). There are a couple of awkward bits along here where care and the use of hands are required for safe passage. On meeting the stream issuing from Cwm Cywion, we ascend a short distance beside it to find a suitable crossing point before continuing across the grassy cwm to meet the path on the east ridge of Y Garn which we follow back to Ogwyn Cottage.

Ogwyn Cottage car park £6, cards accepted. Toilets and tea bar.   Free parking in lay-bys further along the lake (10 mins walk). This is a popular location and parking fills up quickly, hence the early meeting time.
