Fodor's Expert Review Villa Serbelloni Garden

This property of the Rockefeller Foundation has celebrated gardens on the site of Pliny the Elder's villa, overlooking Bellagio. There are only two 1½-hour-long guided visits per day, at 11 am and 3:30 pm, with a maximum of 30 people each, and in May they tend to be booked by whole groups. It's wise to arrive early to sign up at the starting point, at the Bellagio tourist office in the medieval tower in St. Giacomo Square. The garden also closes due to bad weather, so call in advance.
