Points of Interest/Notes on this walk:
The final push onto the summit ridge is very steep and often has a large snow cornice quite late into Spring. It can be extremely dangerous for the ill equipped.
The Crib Goch ridge is not for the faint hearted. It is very exposed and airy in places and can be extremely dangerous - particularly in adverse weather conditions.
The Snowdon Mountain Railway is the only rack railway in Great Britain. It was opened in April 1896 and has been ferrying people to the summit of Snowdon ever since. To date, the Snowdon Mountain Railway has suffered only one fatality.On the day it opened one of the engines briefly lost control near the summit, tempting a passenger to leap from the train. He died from injuries.
Note: The descent from Gallt y Wenallt to Afon Glaslyn is down very steep grass and can be dangerous. In wet weather descend N from point 6 to join and follow the Miners' Track back to Pen y Pass (see walk gw198 for route details).
There is a Snowdon Sherpa bus service that links all the main car parks and starting points for the main routes up Snowdon - including Pen-y-Pass - and the fare is cheaper than parking for the day at Pen-y-Pass- if you can find a space that is. You can buy tickets from the driver (Pen-y-Pass is pronounced 'Pen-uh-pass'). See The Snowdon Sherpa for details.
'Pyg' (as in Pyg Track) is and abbreviation for Pen-y-Gwryd - the hotel at the bottom of the pass.
The building on the summit of Snowdon (Hafod Eryri - The Snowdon Summit Visitor Centre and Cafe) is thought to be the home of the highest house mice in England and Wales!
