For most travelers, 3 days is the ideal amount of time to experience the essence of Lake Como. On the first day, you can explore the city of Como itself, take the funicular up to Brunate for panoramic views, and see the Cathedral. The second day is best spent in the "Mid-Lake" region; you can take the ferry to visit the "Golden Triangle" towns of Bellagio, Varenna, and Menaggio. These towns are compact and can be explored in a single day if you start early. The third day allows for a visit to at least one of the magnificent historic villas, such as Villa del Balbianello (famous for Star Wars and James Bond filming) or Villa Carlotta. If you only have one day, you will be rushed and likely only see Bellagio and Varenna. If you have five days or more, you can slow down the pace, go hiking in the surrounding mountains, or take a day trip to the nearby city of Lecco or even across the border into Lugano, Switzerland.
