Lake Trasimeno (ital. Lago Trasimeno) is in the northwest corner of Umbria in Italy. It is the largest lake in the center and south of Italy, with a surface area of 128 km². No major river flows directly into or out of the lake and the water level fluctuates significantly according to rainfall levels but is at all times fairly shallow. The lake is a popular tourist destination and there are many camping sites, particularly to the west.
Ferries operate to the islands and across the lake, particularly in the tourist season. Obtaining reliable information about schedules in advance is difficult. The main base for the ferries is Passignano. Nearby the lake are:
