If there is still room, passengers are also taken on at the stop beside the Opera House about 15 minutes after the hour and at the Market Square about another quarter of an hour later. From Midsummer to the end of July, the tram can not be rented for private parties. There is always an air of excitement about setting out in a boat. You can experience it in Helsinki during the summer months, when sightseeing tours leave from the quays at the Market Square and Hakieniemi Square about once an hour, starting at 10. There are also day outings from the Market Square to Porvoo, a pretty little city about 50 kilometres to the east.
Prices vary from organiser to organiser, so shop around.
The most inexpensive cruise you can take is the ferry to the sea fortress of Suomenlinna, which costs the same as a tram trip. You have a good view of the harbour and the ships in it on the way to Suomenlinna, which is in a class all its own when it comes to interesting sights and scenery. Visitors who enjoy walking around cities have had things made very easy for them in Helsinki. That is because the Tourist Office has produced a brochure, available in several languages, with suggested walking tour routes, maps and explanations of what one finds along the way. If you have bought a Helsinki Card, you can come along on one for free.
