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.

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.
