Some friends an myself are planning on climbing mount snowdon in summer, but are going there on a camping trip and are thinking of going up via the mountain railway first to identify the climb as we have not done it before. What are the easiest (if any) paths down and are they clearly defined?

There are 7 identified paths on Snowdon, some harder going then others, but all well worth it!
This website should help.

Have fun!

The path to the top of Snowdon are well used and very easy to get to the top and return. Just remember it can be very cold on the top.And there are some very nice camp sites near to the base of Snowdon..All the best

you will have a ball, l climbed Snowdon and l loved it, we went on a path that the welsh mountain guys took us on, l hope you enjoy it as much as l did, good luck xxx
