Experienced travellers recommend going on tourist trips by car; it's convenient and advantageous. If you are going to Wiesbaden, the easiest way to follow the advice is to rent a car. With a car you get full freedom of action and don't need to be attached to schedules of a tourist group, nor to a timetable for transport. Just sit down and go wherever you want, to a busy city centre or to a quiet suburb. Only in this way will you see Wiesbaden in its entire diversity.
A viable car, a massive 4x4, or a hasty hatchback, choose the car you need to calculate the rental cost.
In addition, the price depends on the point where you are planning to pick up the car. Pay attention to this to make the trip more advantageous.
Local rental companies of Wiesbaden may require you to provide an international driving licence.
