You travel on the Autobahn to the
"Heidelberger Kreuz" (Heidelberg crossing), from there on route A 656
directly to Heidelberg.
At the end of the Autobahn you turn
left and then right; you are now on B 37, which you will follow some
minutes, until Heidelberg downtown ends (ca. 5 km). A few hundred
meters, you will see a pointer to "Carl Bosch Museum", which leads you
upwards to the right, across the railway. Then turn left and follow the
streets "Am Rosenbusch" and "Hausackerweg", always climbing upwards the
serpentine curves. The "Hausackerweg" ends by joining the
"Schloß-Wolfsbrunnenweg" at the Hotel Atlantic. Turn left, following
the "Carl Bosch Museum" pointer onto the "Schloss-Wolfsbrunnenweg". 300
m further at your left you have reached the gateway to the Villa Bosch and to the HITS building.
