The UNESCO historical sites included the Castelgrande, Monte Bella are must see. The largest outlet in Europe-Fox Town, is just less than an hour's train.
Bellinzona is a small town and you can find several old castles to visit there. One of them is located just near the main street.
You can take an-hour train to the nearby Foxtown Outlet can you will find many cheap items. Many shops are on sale when I visited the outlet in early July.
