Lugano to Lake Como Possible by Bus?

You can travel from Lugano to Menaggio by bus #631 in 45 minutes. From Menaggio, it’s a 15-minute ferry ride to Bellagio. The ferries make it possible to reach towns all around Lake Como. You might also enjoy taking the ferry to the town of Lecco on the eastern shore of Lake Como. Lecco is a very authentic Italian town and not overtouristed. If you’re looking for a place to eat, a restaurant with delicious cuisine near the waterfront is “Autentico.”
Your Swiss Travel Pass will be valid for these journeys only in Switzerland.

According to Tripadvisor, Bus 631 only runs once a day and leaves Lugano in the afternoon. I've seen Bus C12 suggested but can't confirm whether it still operates and at which stops/times.

you can also take the very short train ride from Lugano to Como San Giovanni and get over to the lake and get the ferries, both fast and slow (I prefer the slow ones) which go everywhere on the lake.

Here is the C112 bus schedule between Lugano and Menaggio. It runs several times per day.

Thanks Sam. I see a lot of results online for C12 not C112 and I don't believe it's a typo. Perhaps the C12 was discontinued?

Can someone please confirm whether I am interpreting the tables correctly,

Departing from Lugano - Stazione FFS Piazzale:

• 6:50 AM
• 8:25 AM
• 9:30 AM

Departing from Menaggio - Piazza Roma:

• 7:07 PM
• 7:48 PM

My interpretation for the return from Menaggio, Piazza Roma is 17:05 and 17:35. Note the 17:05 is only M-F and terminates at the Lugano Cassarate Bus Terminal, and not the Lugano train station.

How did you conclude that? Why not the later times?

I does not look like those buses go all the way to Lugano, but only as far as Porlezza.

Oh I understand now, thank you. I wish we could spend more time in the Lake Como area and leave for Lugano later. I figured there would be a better way. I suppose we could pay more for a private taxi or take the train, but that would be a 2 hr trip back.

Yes, you could take the C110 to Como S. Giovanni station and get a train back to Lugano. Leave Piazza Roma as late as 9:05 PM. That would be 2 hours. There is also a 7:05 PM bus.
