For the Southamerican students is very expensive to travel to Europe. For those from Oceania and Asia, is too far. And for other nationalities the process to get a VISA only for tourism is very bureaucratic. So, since you are in Barcelona with your student VISA, enjoy and travel throughout EU!!!
When you are a student you seek for trips full of emotion and experiences… EU countries are so diverse that you can have very rich experiences and totally different one from another. Furthermore, there are some events that only happen on certain countries, such as concerts, festival, sports events… The easiness to travel that you can find here allows you to travel even if it is for an specific event.
To take a look once in a while on the WebPages is the best thing you can do to be updated for the best rates and opportunities! Companies such as Ryanair, Easyjet, Vueling and WizzAir offer tickets sometimes from 9€ (sometimes even less), and offer more and more destinations.
If you are student and also Works, so you don´t have much time, you can go on weekends… The tickets are more demanded but there is always a good opportunity if you buy it well in advance!
Another advantage is that nowadays there are accommodations for really good prices! Hostel, hotel or apartments for rent to tourists are increasingly affordable and equipped. Airbnb, Housetrip, Onlyapartments and Trivago are some of the companies that offer you a great range of accommodations!
Don´t waste time although you can miss your flight!
Have a nice trip! ;-)
