A wonderful spiky summit with fine views to Yr Wyddfa and into Ogwen Valley. The summit itself is a scramble over very large jumbled boulders.

A high mountain with reasonable length walk-ins. Good scrambling route on it's north side that gives fine views of the 'Balck Ladders' cliff face.

The Castle of the Winds is a true highlight on this or any other mountain. Spectacular and spiky it makes for a great scramble over the top!

You can't miss these two huge stones right on the summit of Tryfan. Traditionally climbers would jump from one to the other to gain the freedom of the mountain. But be warned people have died in the attempt.

The name "Snowdon" is first recorded in 1095 as Snawdune, and is derived from the Old English elements snaw and dun, meaning "hill of snow". The Welsh name for the mountain, Yr Wyddfa, is first recorded in Latin as Weddua vaur in 1284. This is probably an approximation of Pen y Wyddfa Fawr. The element gwyddfa in this context means "height, promontory", and also occurs in the Welsh name for the town of Mold, Yr Wyddgrug. Gwyddfa later developed the meaning "gravestone heap", and there is a legend that the giant Rhita is buried beneath the cairn on the summit of the mountain. According to one legend, the giant Rhita was slain and buried on the mountain by King Arthur, while another legend suggests that Rhita was killed by the giant Idris who lived on the mountain Cadair Idris. The mountain is also associated with other figures from Arthurian legend, a legendary Afanc (water monster) and the Tylwyth Teg (fairies). (Wikipedia)
