How to reach Ondacarta:

from "Tangenziale Est" (the ring road of Milan) take the exit Agrate and follow the signs for Lecco.
After the exit Usmate the motorway ends. Keep straight until the second roundabout with a sign on the right for "Ronco Briantino".
Go pass a railway cross and keep straight; go pass two crossroads. The road leads to the "zona industriale di Ronco" (an industrial area). Take the third on the left and then the first on the right. Ondacarta is at the end of this street.
