Monterosso to Portofino by boat?
 

Can I get to Portofino directly from Monterosso by boat?
Or do I have to go to a different town to catch it?

Not sure about Monterosso, but we took
the boat from Santa Margherita Ligure
from Piazza Martini della Liberta where
the tickets were sold, I think about
6 euros, very short trip. We walked
to the Piazza from the rail station.

Frequent rail links to Santa Margarita Ligure and Portofino boats or buses if no Monterosso-Portofino boats.

I was there late May/Early June and the Monterosso-Portofino boat was only running on Sundays, and it only started up in May (so it is not year round). We weren't there on a sunday and someone said they add days in the summer - I don't know if it goes every day in the summer or not.

Take the 10:18 train to Rapallo then you take take, walk down to the shore and grab the boat from there. Half an hour ride to Portofino.
