Mate Island, 3 km west of Helsinki city center, is located in the center of the lake, connected to the land by a white wooden bridge. The island is lush with green grass and pleasant scenery. We have a walkway along the lake and it is a very good oxygen bar. There were wild ducks by the lake, beautiful pigeons walking around the crowd, and we saw little squirrels, cleverly and unsuspectingly, bouncing around the forest.
