Hi Linda - I suggest you drive up to Como, park your car and take the boat around the lake.  If you do that you can get on and off the boat at the little towns that are all along Lake Como.  If it is a nice day take the slow boat and treat yourself to the beautiful views.  There is also a faster boat if you are short on time.

You can get a boat schedule in Como and plan your day accordingly.  In September it should be beautiful and not as crowded as it can be in the summer.
