Are folders hidden? How do I unhide them?

/Users/Chris/Library/Application Support/Blizzard/StarCraft II/Accounts/


I know that this folder exists on my machine because Starcraft told me this is where replays are stored. When I go to Users/Chris there is no Library folder. There is a library folder outside of the users folder, when I look at all the direct Hard drive folders like System, Users folders etc.

From here I go to Library/Application Support and there is no Blizzard folder. The only folders in there are Apple, avbdeviced, CrashReporter, GarageBand, iLifeMediaBrowser, Microsoft, ProApps, and Script Editor.
