Unfortunately, you can not get from Norway to Finland or back on the ferry. There are no direct flights between the two countries, but if you really want to do at least some of the way on the water, you'll first have to travel to Sweden, and thence to Finland. It is more convenient to travel from Norway to Sweden by land, by train or by bus, since the Sandefjord ferry - Strömstad from Color Line, brings tourists to the port, where flights to Finland do not go. It is best to get to Stockholm (Stockholm) and with the help of the carrier company Viking Line to go by ferry to Helsinki (Helsinki) or Turku (Turku). A trip to the capital of Finland will cost an adult person in 50-70 EUR without a place, the cabin will have to pay an additional fee of 21 EUR, in the summer season - from 47.
