The Instituut-Lorentz is at the second floor of the Oort building (slanted by 7o, next to a tall building covered with black panels).

How to get there: Take a train to Leiden Central Station (20 minutes from Amsterdam Schiphol airport). From the train station, you can either walk along the Rijnsburgerweg and the Wassenaarseweg (20 minutes), or take a taxi, or take bus number 57 to Nieuw Vennep (get out at the stop "Corpus", just before a sharp curve in the Wassenaarseweg) or 43 to Den Haag (get out at the stop "Universiteitsterrein", near a round lecture hall with a red roof). Each bus ride takes less than 10 minutes, leaving the station twice an hour. Be sure to take the bus in the correct direction (either to Nieuw Vennep or to Den Haag).
Here is a detailed map of our neighborhood, and here is a map of downtown Leiden (connected to the detailed map in the upper left hand corner). Some nearby hotels are on this map.

By car: The Oort building can be approached either from the Wassenaarseweg or from the Plesmanlaan, but convenient parking places can only be reached from the Plesmanlaan. There is public parking for a fee near the sport center at Einsteinweg 6, but as a guest you can park for free in the employee parking lot at the Ehrenfestweg: Please ask your host in advance to arrange access as a visitor and then use the intercom to open the barrier.
