Easy! No railway to either, but buses go to Parainen direct from Helsinki every half hour for most of the day. The trip takes about 3 hours. You'd need to change buses to get to Korppoo.

Ah thank you so much, just the website I needed!

Now we know that we don't even have to sort it out until we get there, it seems so efficient! :)

Is it any trouble to change busses, and do you happen to know where we do that, in Parainen perhaps?And if you need to get out on the side of the road somewhere, where there might not be a bus stop..because we don't need to go all the way to korpoo, just need to hop off a little bit before we get to the ferry, is that usually a problem? :)

Thanks again!! :)

It tells you on the website, or you can check it with the bus driver. If there's a language problem, ask the passengers for help - there's always someone who speaks English. Well, nearly always!
