Yes to hiking (although that will depend on whether I meet people to hike with, it's not a good solitary activity IMO), camping in Europe? Nah. I hope I'll get all wilderness-yearning out of my system with Peru. But I do really like nature, especially in the summer when it's beautiful and green and warm. No to shoppping. I like both cities and small quaint towns. My budget is ok. I plan to stay in hostels, to meet people as much as to save money, so that gives me quite a bit of room budget-wise. I know there's a huge range on what you can spend... I did a long weekend in London for the same that it cost me for almost 2 weeks in Spain.
Anyway, primary concern right now is places I want to visit. if they are not in the euro-zone, that's a bonus, but doesn't really matter.
