Snowdon is the highest mountain in Wales at 1,085 metres above sea level. It is located in the Snowdonia National Park in Gwynedd and is described as the busiest mountain in Britain. It was used by Edmund Hillary for training before his 1953 ascent of Mount Everest.
The rocks that form Snowdon were created by volcanoes in the Ordovician period and then sculpted by glaciation. On a clear day, England, Ireland Scotland and the Isle of Man are visible.
The summit can be reached by a number of paths including the Snowdon Mountain Railway, a rack and pinion railway which opened in 1896. At the summit, a visitor centre called Hafod Eryri, built in 2006, replacing the one built in the 1930's offers refreshment.
The name comes from the English 'Snow Hill', while the Welsh name 'Yr Wyddfa' means 'the tumulus' is credited to the final resting place of the giant Rhitta Gawr after his defeat by King Arthur. The mountain is also linked to Afanc, the 'water monster', and Tylwyth Teg, 'fairies'.
