The city of Aosta lies in the northwest corner of Italy. This highly-recommended retreat – the principal centre of the stunning Aosta Valley – offers a huge range of attractions, from stellar cultural sights to outdoor activities. Don’t miss the remains of the 4th-century city walls, known as Augusta Praetoria Salassorum, or the Roman Theatre, which can be reached via paved footpaths from town. Those looking to relax in the mineral-rich waters of the region can head to Pre Saint Didier Thermal Spa or Terme di Saint-Vincent, while the Lillaz Waterfalls also make a fantastic day trip from Aosta. Finally, outdoor enthusiasts are spoiled for choice, with the scenic Gran Paradiso National Park easily accessible, as well as a number of premium ski resorts in the Italian Alps, such as Breuil Cervinia and The Matterhorn.
