Backpacking in Europe expenses would depend greatly on your personal preference and travel itinerary. A) Food. Depending on your preference and taste, food could be extremely expensive or extremely affordable. If you stick with grocery and supermarket food, you could spend somewhere around $10-$20 each day. But then again, if you want a taste of an authentic cuisine in a nice restaurant, theres a price that comes with it. A good blend of the budget spending and a nice restaurant meal is a great way for you to experience both worlds best. B) Transportation. Though this is a backpacking adventure, you still need to spend money on tickets for subway and bus, especially if you want to see as many as you can in the area where youre visiting. To be on the safe side, set a budget of $10-$20 each day for your transportation. C) Attractions. Just like everywhere else, the main attractions that you might want to visit in Europe could cost you. Depending on your locations and what you want to see, budget something around $10-$20 each day for historical exhibits, galleries and museums.
