Day Trips from Lake Como

Where are you staying on Lake Como? It's a big lake.

You might think about taking the train to Tirano and then traveling on the Bernina Express train up into Switzerland.

Is that 5 nights = 4 full days OR 4 nights = 3 full days?

This is going to depend largely on where on Lake Como you are staying. If on the western shore, your carless travels are limited to bus, taxi or ferry. Once on the eastern shore you have train access. If staying in Como itself, your daytrip options change dramatically.

Hi All, thanks for the feedback so far. I've updated my original post to include that we will be staying in Como. The trip will be for 6 full days.

From Como town, you have many options. Milan is definitely worth the day trip (Duomo, Pinacoteca Brera...). So is Lugano, Switzerland. Both are easily reached by train from Como (Como San Giovanni station for Lugano, the same one or Como Nord Lago & Como Borghi for Milan).

Bergamo is an easy day trip from Como. Consider if you are willing to take a train for two hours and Turin is doable, as well as Laveno.
