Isola Maggiore is a small inhabited island in Lake Trasimeno, about 20 minutes from Tuoro by ferry. It is one of only three inhabited islands on the lake and the only one with a village — a tight cluster of stone houses along a single main street, a 14th-century church, and a castle on the southern promontory that was converted into a Guglielmi family villa in the 19th century.
The island is small enough to walk around in under an hour. The main street is lined with women selling hand-made lace, the traditional craft of the island, in small quantities and at reasonable prices. The Guglielmi Castle at the southern end is partially open to visitors. A couple of simple restaurants serve lake fish — eel, perch, pike — in the way that has been done here for centuries. The ferry from Tuoro runs several times daily in summer; schedules are reduced in winter.
