How to get to the MPIfR from Düsseldorf

by Train

Arriving at Bonn Main Railway Station you can proceed either by bus or just take a taxi (the taxi rank is in front of the Railway Station). 

The Main Bus Station is opposite the Railway Station. There are 6 platforms numbered A to F. To MPIfR you take the bus No. 623 (direction LESSENICH; € 2.10) or 621 (direction DUISDORF Bf.; € 1.30) (both leaving from platform E). You should leave the bus at the stop Immenburg. The MPIfR is located on the opposite side of the street in the direction of the bus route.

The ticket can be bought either at one of the machines or in the bus. In the bus you should immediately cancel your ticket in one of the two yellow machines provided (also if it was bought from the driver!). The various stops are normally, but not always, announced by the driver.

Credit cards are not accepted !!!!

by Car

 If you decide to rent a car by one of the rental car services, take the motor way #44 (direction "Ratingen"). At "Autobahnkreuz Ratingen" take #3 (direction: "Köln", "Frankfurt") until "Autobahnkreuz Heumar". 

Now there are two ways to get to Bonn: 

(1) Turn to direction "Aachen" but go straight ahead in direction "Siegburg", do not leave to "Aachen" and take the first possibility to get on motor way #59 at "Autobahnkreuz Gremberg". Go ahead until you get on route #565 (direction: "Altenahr", "Koblenz") at "Autobahndreieck Bonn-Beuel". 

(2) Take the motor way #4 (direction Aachen) until "Autobahnkreuz Köln-Süd". Leave #4 and take #555 until "Autobahnkreuz Bonn-Nord". Take #565 (direction "Altenahr", "Koblenz").

In both cases you finally get on motor way #565 !
Take the motor way exit Bonn-Endenich and turn right at the traffic lights (direction "Duisdorf").

Immediately before the next traffic lights turn right again. The street should be Auf dem Hügel and the institute is No. 69 (on the left side).
In case you miss the motor way exit and end up on route #565, but in opposite direction (to "Siegburg", "Frankfurt"), take the motor way exit Lengsdorf, go right at the exit, ~ 2.5 km to Endenich and turn left to the street Auf dem Hügel.
