Northwest Italy in 9 days

Since you’re arriving in Torino, I would give the third day of Lucca to Torino unless you’ve already made all of your reservations or have a cooking class in Lucca. Torino is one of my favorite larger cities in Italy.

When you’re in Perugia, be sure to go see the painted stained glass laboratory museum & the underground walkway lanes & rooms (read up on both before you arrive).

I wold add the Egyptian museum in Torino as a not-miss. It's the largest outside of Cairo! And lucky you, the International Truffle Fair in Alba is in October (I think on the weekends). Lucca is awesome. Wonderful itinerary!

Just throwing out an option: you could omit Camogli and drive between Torino and Lucca (or a variation that makes sense) and explore the countryside around Alba, as I wish I had done. I had only a brief stay without a car and a lot of rain prevented us from doing so. Much may depend on the truffle fair and such.
But, nothing wrong with what you have selected.

There is so much to see in Piedmont and the Val d'Aosta that you should consider saving Camogli and Lucca for another trip. The 'hunting lodge' of Stupinigi outside Turin is boggling, and the Royal Palace of Venaria is sumptuous. Sacra Michele just to the west on a mountain top is a fantastic 1,000 years old +/- monastery/church. The castles of Val d'Aosta like Fenis and Issogne are unique in Italy. The shrines called Sacri Monte such as the one at Crea are extraordinary cultural artifacts well worth a visit. We've done at least 5 trips to the area and could do 5 more easily.

Jean, thank you for your Perugia suggestions, we completely missed the stained glass and underground walkways when we were there before. We will get them this trip.

Carole, the truffle fair starts the 10th and we have to be in Perugia that day, may be just as well as we can't handle crowds. We are truffle lovers however and will thoroughly investigate the situation. I've been to that Museum in Cairo back when Carter was working to get Israel and Egypt on better terms and Egyptians thought Americans walked on water. It was pretty great back then.

Mike, this was the first I've heard of Stupinigi which went right to the Must Do list. I am researching the rest of your suggestions as well, please keep them coming. How would you allocate 9 days to start in and include Torino and end in Purgia assuming Siena, Pisa, Firenze etc can be skipped?

To all who contributed their expertise, sincere thanks. We've ended up taking the advice and will spend 2.5 days in Torino and the rest exploring a little west, the Susa area, and then SE toward Alba, with 4 days in Alba.

Really looking forward to Alba.

In Torino, the car museum is a great museum, even for people not interested in cars. You'll probably have to take a bus or taxi to it.

One route from the Susa area to Alba would pass near Staffarda Abbey and then the small city of Saluzzo. Both are memorable for a lot of reasons. https://www.apathtolunch.com/2015/12/an-italian-itinerary-small-cities-in.html

If you are near Saluzzo, try to go see the Manta castle with its many secular frescoes such as the fountain of youth:
