Suomenlinna is a treasure trove. There is enormous amount of photogenic places - old ships, forts, cannons. Dry dock area is bustling with activity twice a year when large old wooden ships are taken in and out. In the summer time there are several cafe's open, other times only couple near ferry harbour. Suomenlinna has swimming beaches, museums, brewery restaurant. In summertime the place is beautiful but can be crowded in most popular places. Even after decades of wandering - still possible to find new nooks and crannies - peaceful places.
