Planning?

Ok so yeah hey. I'm Louisa. 19. Student.
So I have nothing to do for 3 months...I know semi-spontaneous backpacking trip? Yes please.
Looking for adventure, new things and change, I booked a flight to Trieste, Italy, for 3 weeks in advance, booked an Inter-rail ticket and that was all I needed.
Thats it. Longing to do many of the things I have heard so much about. A little planning. Pack up and go.
Countries I planned to hit where Italy, Slovenia, Austria, Switzerland and finally France before heading home. Hopefully try some sports and a bit of random adventure.
So thats it, get out there, do it and live a dream.
