Tis is the crossing of the Ffestiniog Welsh Highland Railway at Rhyd Ddu. once through the crossing the surface becomes compact gravel and climbing. It is rideable but takes effort

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

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.
