Two legends are attached to this mountain.
The first is that it’s the only mountain in Wales you can’t climb without using your hands – the scramble up its jutting crags requires considerable concentration and a head for heights. The second is that by making the leap between two pillar-like rocks at its summit (3,000 ft/915 m) you earn the “Freedom of Tryfan.”
Tryfan Welsh pronunciation is a mountain in the Ogwen Valley, Snowdonia, Wales. It forms part of the Glyderau group, and is one of the most recognisable peaks in Britain, having a classic pointed shape with rugged crags. At 917.5 metres (3,010 feet) above sea level, it is the fifteenth-highest mountain in Wales. Tryfan was voted Britain’s favourite mountain by Trail magazine.
Between the mid-1980s and June 2010, its accepted height was 915 metres (3,002 ft). However, it was resurveyed using accurate GPS measurements and found to be 2.4 metres (eight feet) higher (which the pre-1980s surveys also recorded). Wikipedia
