Y Garn is a fine hill, usually climbed from Ogwen Valley by it's West ridge, or as part of the walk along the Glyders range between Elidir Fawr and the Glyders themselves. There is however another way up, the East Ridge, which is a Grade 2 scramble and starts from Llyn Idwal.

Take some time to enjoy the peaceful atmosphere at this small mountain lake Llyn Y Cwn (Welsh for Lake of the Dogs). The peak of Y Garn rises to the north and Glyder Fawr looms to the south-east. You really are in the mountains here!

Llyn Idwal is a lake (approximately 800 by 300 metres, or 28 hectares) in Cwm Idwal in the Glyderau Mountains of Snowdonia. On the north-western edge of Llyn Idwal is a small pebble beach, which is occasionally used by visitors for recreation. Swimming is not permitted as it is in a nature reserve.

It can be windy and cloudy here. There are marks to find a trail in the cloud. Also on the top there is a nice area to hide from wind and rest. If not in the cloud, the view is awesome
