​Time to wander through Helsinki's wartime history 🪖 Discover an area full of WWI-era fortifications that remains hidden in the forest 🌲🧱 ​This will be a day hike, close to the city (transport-wise), but far enough for the traffic to get muffled by nature. Expect forest paths, some muddy sections, and a lot of old concrete ominously sitting where it was left over a hundred years ago. Perhaps slightly unsettling, probably a chance for some epic pictures 😎 ​The participation in the hike is free for members and fee for non-members is 5€, which includes planning, guidance along the way and best company you can ever meet! Please note, each participant covers cost of own transportation tickets and snacks.
