Helsinki is the capital of Finland.
Where You're Docked
Large ships are docked at two possible piers southwest of city, Hernesaari (LHC & LHB) or West Harbour (LV7 & LMA). Smaller ships can dock much closer to the city at South Harbour (EKL, EPL, & EO1) or Katajanokka (ERA & ERB) relatively close to Market Square. If a shuttle is offered, it may drop off at Erottajankatu across the street from the western end of the esplanade. The Local Transportation section provides information on getting to the city center on public transport.

Day in Helsinki
Starting at the end of the esplanade, take a walk through which will lead you to Market Square. Grab a bite to eat here or do some souvenir shopping. Head north one block over to Senate Square where you can climb the steps to take a look at the Helsinki Cathedral. Two blocks to the east is the Russian Cathedral if you're not churched out. Head back to Senate Square and walk west along Aleksanterinkatu. There are lots of stores and restaurants in this area. Turn right before the main road to check out the railway station. Your next stop, the Rock Church, is a bit hard to find so you'll need a map. It is about 3/4 of a mile away almost directly west. You can walk or take the #2 tram (previously 3T) to stop Sammonkatu. Return on the #3 tram.
If you have time, you can take a bus or tram to see the Sibelius Monument since it is more difficult to get to. Take tram 2 (return with tram 3) to Toolonhalli but you will need to walk a bit to reach the park. You can also take bus 24 from the railway station which will get you closer.
