To come to Monza by car from east or west you should take A4 highway (Turin-Milan-Venice) and exit "Monza", from north the Milan-Lecco expressway (ss36) which ends in the town. From south you'd better take Milan's "tangenziale nord", which starts from "tangenziale est" and then Monza exit.
To arrive by plane, please refer to Milan#By_plane.
TPM operates a small public transportation network, you are supposed to buy tickets in advance and validate it once your trip starts. Tickets are urban and inter-urban (for travellers willing to cross city border) and both are valid for 60'.
The public transportation network is not used so much by "Monzese" people because of the small dimensions of the city. Reaching the centre by foot from the periphery will take you about 20'.
Bike are heavily used by Monza inhabitants and there's a nice ring of bike-reserved lanes on the banks of Villoresi Canal.
A walk thru the Parco di Monza, you'll understand why Monza people love so much their park. Very crowded during weekends.
