Please note that there are only a few parking spaces available for visitors on the Max Planck Institute for Astronomy (MPIA) campus. If you are arriving in a group with private cars, please refer to the large parking lot at the Bergbahn / Märchenparadies (about 10–15 minutes walk away).
If you are attending a public event at the Haus der Astronomie (HdA) after 16:00, the institute's internal parking lot can be used. Please note that the use of the parking lot  is only permitted within the time frame of the event visit.

A parking lot is available for coaches in front of the MPIA entrance gate, and there are further coach parking spaces a few minutes' walk away (navigation to Märchenparadies / Königstuhl).
