Day Trip to Suomenlinna – Need comprehensive details?

If you are in Helsinki, then a day trip to Suomenlinna, or Sveaborg is a must. It’s a stunning sea fortress built on eight islands about 4 kms southeast of the city centre of Helsinki. The sea fortress has free entrance and you only need to pay for the ferry.

But if you already have the Helsinki Pass, then the entire day trip to Suomenlinna becomes free.

How to get there – Suomenlinna from Helsinki?

A HSL ferry service runs from the Market Square to Suomenlinna. The trip to Suomenlinna takes approximately 20 mins and you get some stunning views of the city of Helsinki from the ferry.

TIP – You might be tempted to be be seated at the first seat on the top deck of the ferry but be warned that the winds are pretty strong and it can get really cold.

Things to do in Suomenlinna

The fortress is big and has museums and some occasional exhibitions. Therefore, to make the best use of your time I would suggest following something called the Blue Route. It covers all the major attractions and that way you won’t miss out of anything important. The route has blue direction signs.

It also helps to have the brochure with you.
