Excellent sight looking across Llyn Peris which is 503mtrs above sea level. Dinorwig hydroelectric power station is straight across the lake, this generates 1728MW of power. There are 16 kilometres of deep tunnels in Elidir Mountain. This was opened in 1984

The visitor centre is located on the A5, approximately 5 miles south of Bethesda and approximately 4 miles west of Capel Curig, on the western side of Llyn Ogwen. There are a number of facilities including toilets, disabled toilets, an information room, public wifi and a small kiosk selling hot and cold snacks. From the visitor centre you can start a range of walks and climbs in the area. The most popular is the walk to Wales' first ever national nature reserve, the beautiful Cwm Idwal, a glacial lake with a mountainous backdrop. (Cwm Idwal National Nature Reserve)

If you want to park here, you have to reserve a parking space in advance for 20 GBP. We didn't manage to do it, as everything was fully booked. You can then park in Llanberies and take the Sherpa Bus S1 or S2 to Pen y Pass. The bus runs every half hour. From Pen y Pass, you can then choose the Miner's Track or Pyg Track. Have fun!

Right opposite the layby are the two main blocks - a good description and link to the topo is at https://www.climber.co.uk/outdoor/bouldering/around-the-bloc-the-cromlech-boulders-llanberis/ There are more higher up on the hill and you will find boulderars here at most times of the weather permits.

Currently parking is pre-booking only! All others are directed to the P+R in the village and need to get up by bus or walk.
