We are thinking about doing a 2-week backpacking trip in Europe for our honeymoon! Mostly Italy, maybe Greece, Germany, Switzerland...? I went to Europe as a teenager for a short trip, and also studied abroad in Spain during college, but haven't been since!
We do a lot of outdoorsy stuff - cycling, hiking, camping.... Would love to do some of that out there, but also just RELAX

I'd really prefer to get off the beaten path and see some non-touristy stuff too. We will be going late August or early September 2014.
Does anyone have any suggestions for places (countries, cities, activities) not to miss out on? There is just so much to see, and never enough time!
