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.

Poor Elidir Fawr! It has been bashed about and big lumps knocked out of it at Dinorwic Quarry, it has had a power station built inside it, and has a reservoir for that reservoir almost at the very top. Fortunately when you climb it from Nant Peris you will only see the reservoir, the rest of the damage is ot of sight.

A high mountain with reasonable length walk-ins. Good scrambling route on it's north side that gives fine views of the 'Balck Ladders' cliff face.

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.
