|Subject: Re: Santa Margherita Ligure to Bellagio|
as Paolo suggested, you have to take a train from Santa Margherita to Milan, change train in Milan to Como (have a look at http://www.trenitalia.com for timetable). In Como you can go to Bellagio by bus (http://www.stpcomo.it click on orari then Linee Extraurbane and on C30 Como - Bellagio or C250 MENAGGIO-COMO-AEROPORTO MALPENSA to go to Malpensa from Como).
If you prefer go to Bellagio by boat, http://www.navigazionelaghi.it then click on Lago di Como, Servizi and on timetable.
Since some site are only in Italian, contact me for help.
Ciao, Marco in Milan - Italy
