On Monday (10 January), the country’s "super green pass" requirement was extended to a range of additional venues, including hotels, public transport, outdoor and indoor hospitality, museums, cultural spaces and festivals.
The pass, which can only be obtained with evidence of full vaccination or recent recovery, is also a requirement to access ski lifts and ski resorts.
This means a negative test is no longer sufficient for unvaccinated travellers to ski in Italy.
Meanwhile, bookings for ski holidays to Austria and Switzerland have reportedly increased as France remains off limits to British tourists.
