3. Switzerland
Cost of travel for a month for one person: $5,282
If you can spend over five thousand on a month in Luxembourg, then you may as well want to take a look at Switzerland. It is certainly one of the most beautiful countries in Europe and one of the most peaceful as well. The country is a heaven for any outdoors people since you can hike, ski and do all that good stuff there and soak in nature in its raw form. Also, you will not miss the busy city life if you travel to Zürich, Basel, Bern, and Lausanne.
