Alright guys, I'm 19 years old and am planning a backpacking trip to Europe or maybe Cuba. I'm planning to travel alone and am planning to commit 30 - 45 days for backpacking in Europe. As there are budget constrains, I am hoping to have some recommendations on the must visits and how to make the most out of my buck. I'm looking at visiting Eastern Europe for the most part but with a limit of 45 days, I can't quite make up my mind on where to go. I would love to visit every corner of EU though. Hopefully some locals or frequent travelers can recommend places.
