Expo 2015 (officially "Universal Expo Milano 2015") will take place in Milan from May 1 to October 31, 2015.

It can be reached from the subway stop Rho Fiera Milano (which is on the line RED) and follow signs on site.

You can get to the underground station by any means: plane, train, bus or car (there is a large car park from which then you have to take a special free shuttle).
