Students are, after the first month, free to travel beyond Paris and beyond France on weekends, at their own expense (as long as such travel does not conflict with class schedules). With such affordable and convenient methods of travel within Europe, many students organize short excursions to London, Barcelona and other destinations of interest. That being said, with so much to see and do in the Paris region, many prefer local, affordable trips such as a day spent with other students out at Versailles as study time allows.
