Leaving the main entrance, turn left and follow the tram rails downhill.
After 200 m?, you reach the Hládkov tram stop. Here you can take tram 8, 22, or 23 to Vozovna Střešovice (1 stop), but it is better to turn right (still along the tram rails) to continue to the Sibeliova stop, from which trams go directly to the Institute.
Behind the crossing, turn left uphill using the steps.
Pass a short piece of U laboratoře street to Střešovická street with tram rails.
Turn left to the Sibeliova tram stop and take any tram (1, 2, 18) to the terminal Petřiny, following general description of the way to the Institute.
