Directions:
The Physikzentrum Bad Honnef is located at the bank of the Rhine.
Hauptstraße 5, 53604 Bad Honnef, Germany
By train
From Cologne from the direction of Koblenz (right side of the Rhine) to the stop „Rhöndorf“.
From Frankfurt either via Siegburg (ICE) to Troisdorf and then to Rhöndorf (right side of the Rhine) or via Koblenz and then to Rhöndorf (often cheaper with the same journey time).
It is a 10 minute walk to the Physikzentrum or take bus 566 to the stop „Meßbeuel“.
From Bonn take the S-Bahn line 66 to the stop „Am Spitzenbach“, which is a 5 minute walk from the Physikzentrum Bad Honnef.
Taxi in Bad Honnef and Rhöndorf: Tel.: +49 (2224) 2222 or +49 (2224) 2121. From Rhöndorf the PBH can be reached on foot (approx. 10 min, see city map) or by taxi.
By Car
From the north via the A3 – Heumarer Dreieck – A59 continued as B42 to Bad Honnef – exit Rhöndorf, follow the Rhöndorfer Straße, which becomes the Hauptstraße (approx. 2 km), on the left side you will find the Physikzentrum (corner Meßbeuel).
From the south via the A3 Frankfurt-Köln exit Bad Honnef-Linz through the Schmelztal to Bad Honnef, follow the main road until you reach a sharp left turn, then immediately turn right again (Am Saynschen Hof). Follow this road (priority road) for approx. 1.5 km, you will find the Physikzentrum Bad Honnef on the right-hand side.
