Spend time by the sea and visiting the port in Ancona.
Plan a fun excursion to Porto di Ancona and Palaindoor while here. You might find that sights like Piazza del Plebiscito and Teatro delle Muse are worth a visit.
If you want to stretch your legs and breathe in some fresh mountain air, head out to Mount Conero for a bird's-eye view of Ancona.
