<human>: Can you condense the text into a few key points?

I am traveling with a couple friends....we are in Italy at the moment, and they are going to Spain to backpack a trail for the next few months, but I am not sure I want to. I am thinking of splitting off and getting a Eurorail global pass for 3 months, which would leave me with roughly 790 euro for food, lodging, and reservations for trains (between 2 and 10 euro each). I am a member of Couchsurfing, and have camping equiptment. I would love to go to Switzerland and Scandanavia....

I guess what I need is information on the availability of free camping or places to backpack, specifically through Switzerland and Scandanavia. I have a flight booked for back home in mid December, so I am hoping I can make that money last. I am used to the Sierra Nevadas, where it is easy to just pick a trail, peel off, and camp.  Any advice is appreciated!
<bot>: I would love any information on the legalities and availability of backpacking through Scandanavia, Switzerland, and anywhere else.
