Travel tips from CHO

Go on the first Sunday of the month

State museums, archaeological parks and monuments across Italy open free of charge on the first Sunday of every month. It covers state-run sites only — civic and private museums set their own prices — and there is nothing to claim: you simply walk in.

In September, the doors that are usually shut open

For one long weekend every September, some fifty European countries run the European Heritage Days together: palaces, workshops, archives and private houses that are closed the rest of the year let visitors in, almost always for nothing. Italy sets its own dates, and they are published a few weeks ahead.

Arrive already connected

Maps, opening hours and tickets all need data, and roaming outside your own network still costs more than the ticket. A travel eSIM for Italy installs on your phone before you leave home and works the moment you land — no queue at the airport, no physical card to swap.
