is it easy to find shrooms in germany/aust/switzerland?

hey im going over to germany austria and switzerland in the summer on a school trip. all we are doing islike seeing sights and touring towns and stuff, we get som hours a day free to walk around and explore so i was thinking im gonna munch some mushies while im over there. i was just wondering if anyone has been there or could tell me how the situation is over there.

thanks in advance
