Piedmont layers Turin's Egyptian Museum (the world's largest outside Cairo) and the Mole Antonelliana, the Langhe wine hills of Barolo and Barbaresco, the truffle country around Alba, and the Lake Orta's quieter shore.
White truffle season in the Langhe peaks October-November with Alba Truffle Fair, Barolo and Barbaresco harvest mid-September, and chestnut harvest across the Monferrato hills.
Piedmont vineyards leafing out, Salone del Mobile Milano in mid-April aside, and the Langhe at peak photogenic before summer haze.
Turin hits 30°C and Piazza Castello bakes, but Lake Orta and the Alpine valleys at Sestriere stay 8°C cooler, and the Cesana ridge accessible for hiking.
Sestriere and Bardonecchia ski December-April with the 2006 Olympic legacy, Turin Christmas market at Piazza Solferino, and Bagna càuda dipping season at peak.
