From what the guys said Snowden is the easiest, in fact after the trip I went with Wife & Son and walked up Snowden. There are several paths available of different difficulty levels
Cheers Posh, Snowden would seem the easiest out of the three plus the nearest to get to. Many get caught out on Scafell Pike due to it being brutal from the start even though it’s the shortest out of the three. Ben Nevis is another level and not to be taken lightly.
