How to get to the MPIfR from Frankfurt

by Air to Cologne

These are the options for getting from Köln-Bonn Airport to MPIfR.

by Train to Bonn

Now the IC/EC trains which go directly to Bonn run only every 2 hours!

The other trains are the fast ICE trains which run to Cologne (and further) on the other side of the Rhine (because the winding track on "our" side is not suitable for these high-speed trains).

With the ICE trains you first go to Cologne and then return to Bonn with the next available train. These ICE trains also pass Siegburg, but only every second stops there. So for those which stop in Siegburg the alternative is to leave the train there and then take the tram #66 (so-called Telekom Express) to Bonn Hbf (arrives in the underground area below the Main Railway Station).

And then one continues to the MPI by bus as in the other case. For someone coming to the MPI for the very first time, it may be easier to always go via Cologne (but also the most expensive alternative (see below).

The worst change are the fares:
IC or EC train directly to Bonn costs 30 Euro
ICE to Cologne and return to Bonn by a regional or IC/EC/ICE train costs 59.00 Euro
ICE to Siegburg costs 45.00 Euro + 3.80 Euro for the tram ticket to Bonn (incl. the connecting bus trip to the MPI).

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 tickets 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

Make your way to Bonn on motor way #3 (direction "Köln").

After about 150 km, at motor way crossing "Autobahnkreuz Bonn/Siegburg", leave #3 in direction Bonn (#560). At "Autobahndreieck St. Augustin-West" take #59 until you get on route #565 (direction: "Altenahr", "Koblenz") at "Autobahndreieck Bonn-Beuel".

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.
