Lake Trasimeno is definitely a place that you should include in your itinerary. I want to clarify that the lake is in Umbria, which is the region bordering Tuscany and so it is really close as you can see on the map below:
Lake Trasimeno in addition to being the third largest lake in Italy is not only interesting for its size but also for its scenery.
The lake is surrounded by very attractive small villages worth visiting; the most famous are Castiglione del Lago and Passignano sul Trasimeno. The first is especially beautiful and the second is where you will find two of the best restaurants in the area who cook both fresh fishes and saltwater.
A visit to Passignano at 7 pm is recommended during the summer months. Have a drink or a beer while watching the sun set over this beautiful lake is a wonderful ifeeling (published photographs are taken in Passignano). Recommended restaurants would be Spinnaker (Passignano same) and Fischio of Merlo. The second is from my point of view the best fish restaurant in the area. Both restaurants are a tiny bit expensive (about 40 euros) but are worth it.
Lake Trasimeno is a beautiful and unique place and should be included in a visit in Umbria with other attractions such as Assisi, Gubbio and Montefalco but we will discuss this in another post.
