Escorted Rail Tours to Lake Trasimeno
Castles by the lake
Being just slightly smaller than Lake Como, Lake Trasimeno is one of Italy's most popular and largest lakes. The lake was formed about three million years ago, when a depression formed by geologic fractures drained what was a shallow sea across Umbria into a much smaller space. For thousands of years afterwards, the lake was still much larger than it is today; for a long time it extended almost as far as Perugia. This is unusual considering no major river flows directly into or out of Lake Trasimeno.
