Me and my best friend are making plans to go backpacking through Europe. We were wondering what are some of the best places to visit?

Hi
Its my birthday end of February and I wanted to go away for the weekend with my best friend to celebrate as our birthdays are a few days apart. We’ll be 26. What is the best place in Europe to visit at that time. We both like picturesque kind of places and enjoy fun sports. Do you have any suggestions?
