Travel by bus from the center of Heraklion to the Math-Department
The workshop venue is easily accessible by bus from the city center. Both bus number 11 (PANEPISTIMIO/PAGNI) and bus number 8 (ITE) service the Math Department from downtown Heraklion, with a journey time around 30 minutes. While both these lines stop throughout the center on their way to the university, two prominent stops are Eleutherias Square and Chanioporta.
Bus tickets can be purchased either from the dedicated machines at the major stops (usually cash/coins only), or from any of the small kiosks/tobacco shops throughout the city. The ticket required for this journey is typically referred to as a "blue" ticket, and should cost around 1.60 euro each way. In principle you can also buy them from the driver with a small surcharge.
To return to the city center from the university, you will take either bus number 1 (AERODROMIO) or 20 (LIMANI) from in front of the physics department (both pass through the center).
