At the southern tip of Finland, Turku lies at the end of the mainland before the beginning of a large archipelago of islands, across from Sweden. A great way to see the city is the Jakke River Ferry. It tours along the Aurajoki River which is central and also includes a tour on a small train to give you an all rounded circuit. Given its location, Turku is a hub for smaller towns based just outside it and so it sees a lot of external visitors, especially due to the port that connects it to Sweden. If youre hiring a car in Turku, then just outside the centre are the Virnamäenpuisto and the Nummenranta parks, both based along the main river they are the ideal place to spend the day at with a picnic.
