Structure

Cloggy is north-facing and a comparatively remote mountain crag, that requires a long walk-in to access from Llanberis. The cliff is broken into several large buttresses, most notably: ''East Buttress'', ''The Pinnacle'' (lies above the ''East Buttress''), ''West Buttress'', and ''Far West Buttress''. The cliff's circa in height and mountain elevation, combined with the steepness and quality of rock, gives it the feel of a face on an alpine mountain.

Climbing history

The first recorded climb was the 1798 ascent of the ''Eastern Terrace'' by Peter Bailey Williams and William Bingley, both botanists looking for alpine plants. However, it was not until the 1920s, that British rock climbers began to scale the main buttresses, starting with the ''East Buttress'' in 1927 (

While the cliff contains routes of all difficulties, few other crags in Britain contain such a concentration of routes above the extreme E7-grade.
