Piedmont is a year round destination. Come in early spring (Feb-March) to catch the ski season; in late spring (April-May) for flowers and fruit-tree blossoms; in summer for long hot days and in autumn for the truffle season. Wine harvesting season also spans September and October but, happily, tasting happens all year round.
Piedmont is rich in festivals, including the Asti Carnivale and Ivrea's "Battle of the Oranges", both in February, Maranzana's Festa dello Spumante (sparkling wine festival) in August, the Palio Horse Race (older than Siena's) every September, the Alba Truffle festival in October, and the White Truffle festival in November.
Note: flight, boat, train and bus timetables change constantly, and airlines come and go, so please do not rely solely on this information for your travel planning. Check with relevant companies, or a flight search engine like Skyscanner, first.
