Suomenlinna is one of the favourite outing spots for locals. It makes an excellent afternoon outing - in summer the connecting ferry is packed with jolly people and picnic baskets. It is a world heritage site, having just celebrated its 250th anniversary, but 900 people live there, too, and 350 people work there daily.
The ferry leaves about every 20 to 30 min from the far end of the market square, public transport tickets are valid. It is best to buy them well beforehand at the kiosk or at any R-kiosk 10 mk a piece, more convenient than trying to buy one aboard. I find I always have to run to catch the ferry!
The fortress consists of a number of islans, each with its very own character. The island with the port is like a little historic town: a shop, charming villas, a church (yes, summer weddings and horse-drawn carts) as well as a gallery, brewery and the sorts.
There is a small Naval Academy on a little island off this one, but that's off limits.
The next island is monumental, historic, full of granite grey walls, monuments and stone buildings. Here there are also artesan workshops, museums and a couple of villas tucked away on the more sheltered side. There is also a shipyard (last time the basin was dry), and a little harbour beyond there - apparently they have a sauna there, in addition to the little pub. But cross the island and suddenly over the ridge you will see the Baltic, glinting blue, possibly windy, and below lovely smooth inviting rocks for sitting down and watching seagulls soar on the wind. (now, who has the bottle opener?)
There are tunnels in the walls, some of them large and open, but one which is narrow and absolutely dark...
The last island is the starkest of all, with just cannons and the bastion walls but a lovely spot in the middle, and also in one grey granite construction a nice bar and a pizza place (!).
This is the low-budget approach to Suomenlinna, surely you can dine here well enough, but our economy walks are based on the invigorating effect of fresh air and picnic supplies.
It can get windy, it is an island out as sea, so bring something windproof, but there are also nice sheltered spots for the enjoyment of all. If you are brave enough, bring a swim suit, there is a little swimming beach, too.
