An awe-inspiring mountain crag, hosting an impressive selection of classic routes, including some of the most famous rock climbs in Britain, such as Johnny Dawes’ E9, Indian Face. The dark shadow-cast form of the cliff, coupled with the still beauty of the adjacent Llyn Du’r Arddu, creates an air of peaceful serenity. Cloggy, as it is affectionately known, invokes a deep sense of attachment from its many devotees.
Away from the head-spinning difficulties of bold E9s, there are a plethora of atmo¬spheric and adventurous mid-grade routes, particularly in the VS – E4 range. That said, the situations on the crag can be quite serious, and a level of multi-pitch competence is advisable for all members of the team. The rock is generally sound, however loose and creaky sections will be encountered in places and rock fall is always a possibility, especially when other climbers are around.
The altitude and aspect ensure that suitable climbing conditions are only likely between the months of May and September. This is a generally shady crag, however in the early morning and evening sections do catch the sun. Cloggy has a reputation for being slow-drying, and this is certainly true for many of the routes, particularly the corners and cracks. However, several of the open face routes actually dry very quickly.
The crag can be reached by branching off right from the main Llanberis Snowdon summit path 700m after the Halfway House café.
