Clogwyn Du'r Arddu, Rock climbing cliff in northern Snowdon, United Kingdom
Clogwyn Du'r Arddu is a rhyolite cliff in northern Snowdonia, Wales, rising about 300 meters (980 feet) with multiple buttresses and sections. The rock face holds more than 200 established climbing routes of varying grades spread across different parts of the wall.
The first recorded visit came in 1798 when botanists climbed the Eastern Terrace while searching for alpine plants. Over the following centuries, the cliff became a center for developing and testing new climbing techniques in Britain.
The cliff holds deep meaning in British climbing culture, as climbers from different generations have tested themselves on its routes and shared their knowledge here. This place remains central to how climbers measure their progress and connect with others who love the sport.
Routes here range from beginner-friendly grades to very challenging climbs, giving different abilities something to try. Weather can change quickly on the north-facing wall, so checking conditions before you go is important for safety.
In 1986, a climber completed a technically demanding route on the Great Wall section that remains one of the hardest traditional climbs at this site. This route has become a testing ground for climbers seeking to push their abilities to the highest levels.
