One of the must-see attractions in Helsinki During this excursion, you will also visit Seurasaari (known as “Squirrel island”), an open-air museum located on a beautiful green island just a few kilometers from the heart of Helsinki. The island is an oasis in the middle of the city and the museum, open in summer, displays the traditional Finnish way of life with its cottages, farm houses and manors from the past four centuries that have been brought here from all over Finland. The tame birds and squirrels provide a warm welcome to all visitors. The museum has 85 different buildings that tell about the lives and folk traditions of the local people in times past.
