hile walking, plan to visit the main museums of Rome.
During the summer, from June 25 to September 3, the Museums are open to the public from 20.00 to 01.00. Last admission is scheduled for 24.00.  The culture …. not timed

ROMA PASS (about 20 euros)

you can buy a Pass in many museums, including:

– free access to the first two visited museums,

– discounts on access to museum or other  archeological sites,

– ticket for the entire transportation network of Rome.

This is a good idea, although I live in Rome, I have purchased it several times.

Take the BUS 116  This is a small, electric bus that goes through the heart of the historical district. It goes from Borghese Park to the Vatican City.

It stops near Piazza Barberini, Spanish Steps, Sant’Andrea, Trevi Fountain, Piazza Navona, Pantheon, Campo de Fiori.
