Clogwyn y Garnedd, or the Trinity Face if you prefer the English moniker, sits in a magnificent position right beneath the summit of Snowdon. This sprawling, snowy expanse provides some of the most reliable winter climbing in Snowdonia. The abundance of classic gully lines in the lower grade range further adds to the allure. Unsurprisingly on busy weekends it can be over run with hordes of winter climbers, all of them hungry for a fix of snowy action.
Outside the main gully lines there is a fair amount of modern style turfy mixed climbing, but a word of warning: protection is sometimes alarmingly sparse.
Sections of the cliff are home to rare plants – for full details check out the North Wales White Guide.
The altitude and orientation of this summit cliff ensure the regular occurrence of climbable winter conditions. That said, most of the routes are considerably safer and less harrowing once the snow has firmed up into good quality neve. Once established the main gully lines, particularly the easier ones can stay in condition right into April. The right side of the cliff, particularly the Cave Gully area (which is home to several excellent routes) is one of the most ‘wintery’ places in Snowdonia.
From the Pen y Pass car park follow the PyG track until it is possible to break off leftwards to reach the snow bowl below the cliff.
In exceptional winters the neighbouring Lliwedd comes into condition and provides some big and often serious winter challenges. On the other side of Snowdon Clogwyn Du’r Arddu offers more dramatic winter routes, although these are mostly in the harder grades and again require strong winter conditions to be worthwhile.
