Tryfan is a mountain in the Ogwen valley, Snowdonia, Wales. It forms part of the Glyderau group, and is one of the most famous and recognisable peaks in Britain, having a classic pointed shape with rugged crags. At 3,010 feet above sea level it is the fifteenth highest mountain in Wales.
There are many routes of ascent, ranging from easy ridge scrambling, to long mountaineering rock climbs on the east face. Tryfan is one of the very few mountains in Great Britain, apart from the Cuillin of Skye, to require the use of hands (as well as feet) on the ascent. However there are a number of peaks (notably Helm Crag in the Lake District and The Cobbler in the Scottish Highlands) that involve a scramble to reach the highest point.
