Giardini di Villa Barberini

Gardens in Castel Gandolfo & Lago Albano

For centuries a closed world, the papal gardens at Castel Gandolfo can now be visited, albeit accompanied and in groups. The regular one-hour tour involves a mini-train ride through the extensive gardens, taking in Roman ruins, flower displays, woods, fruit 'n' veg patches and the papal helipad.

To explore on foot, there are scheduled Saturday morning visits when you're free to walk around accompanied by Vatican staff – see the website for details of this and other visitor packages.
