Sup /trv/ ausfag here

im planning on going to europe in the next few years. however, i can't decide if i should go on a tour, or backpack around for a few months. Or possibly a combination of the two. If i do back pack, what kind of jobs would anon recommend me supporting myself with? Money will more then likely be tight since it'll cost me a fortune to get over there

I have my heart set on going to Ireland, germany and sweden. where else are 'must see' destinations?
