A Few Facts About Elidir Fawr

Location -
Elidir Fawr is a mountain in Snowdonia, the northernmost peak in the Glyderau. To the north of the summit is a small lake, Marchlyn Mawr, which is the upper reservoir for Dinorwig power station a pump-storage power station hidden inside the mountain. Water from this lake flows through huge tunnels into the lower reservoir Llyn Peris. From the north Elidir Fawr is very prominent and can appear to be higher than the higher mountains behind it. From Llanberis the mountain is dominated by the former Dinorwic slate quarries and the waste they have left behind.

Summit -
It is a reasonably short, but steep walk up to the summit, and this can be undertaken from the Deiniolen side or from Nant Peris (which is probably the most popular of ascents). The Deiniolen walk provides views down to Llanberis, while the Nant Peris approach is short and quite steep. The summit can also be reached from Ogwen Cottage via a traverse of Y Garn and Foel-goch. The route makes its way around the headwall of Cwm Dudodyn to Bwlch y Brecan and up to the rocky summit of Elidir Fawr. The summit as already mentioned is very rocky with lots of stones and boulders scattered about. It has a main cairn and a windshelter. Elidir Fawr stands at 924 metres (3,031 feet) and is one of the Welsh 3,000 mountains.
