    Rock climbing

    Right opposite the layby are the two main blocks - a good description and link to the topo is at 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.
