The drive is 164 km against 132 km as the crow flies, which is the ordinary shape of a German motorway journey. That is 1h 51 in a car that waits for you rather than the other way round, at a fare quoted in full at booking.
The fare is fixed when you book, so a closed lane or a slow stretch costs you time and not money — there is no meter and no waiting charge. Pickup is any address in Cologne: a home, a hotel, an office, a venue. Drop-off is the exact address in Wiesbaden, not the nearest station to it. The route crosses from Nordrhein-Westfalen into Hessen; the price covers the whole of it including tolls. The same fixed-price arrangement covers Cologne to Darmstadt, a separate route with its own measured distance.
One vehicle the whole way, one price, and a departure time you choose rather than one a timetable chooses for you. Journeys this length are mostly booked the same day or the day before, and the car can be at the door within the hour in normal conditions. Arriving by air instead? Cologne Bonn Airport Transfers covers every destination we serve from the airport.
