By plane
Nearest airport IATA: POR (http://www.finavia.fi/airport_pori?airport_url=%2Flentoasema_pori) is located in the neighboring city of Pori. Another option is Turku IATA: TKU (http://www.finavia.fi/airport_turku), which may have slightly better connections abroad. If you fly in from abroad, it may be quicker to fly to Helsinki IATA: HEL (http://www.helsinki-vantaa.fi/home) and continue by bus or train than to wait for a connecting flight to Turku. Tampere also has some international flights, most of them operated by Ryanair.
By ship
There is no commercial passenger traffic by sea but many tourists, especially Finns, arrive in Rauma with their private yachts. There are a few guest harbours around Rauma.
By train
There is no passenger rail traffic directly to Rauma. However, you can buy a train ticket to Rauma from VR (http://www.vr.fi/). The train takes you as far as Kokemäki, where you'll change to a bus included in the price for the rest of the way. This is convenient for example if you are Interrailing. From Helsinki it takes about four hours to reach Rauma by train. You should also consider taking an alternative route of taking a train to Turku and then a northbound bus to Rauma. This may also be faster than taking a direct bus, depending on the time of day, but the Turku-Rauma bus is not included in the train ticket.
By car
There are easy road connections to Helsinki south via Huittinen, 242 km, Tampere east via Huittinen, 145 km, Turku south, 94 km and Pori north, 49 km. There are no roads going west since that way lies the sea.
