Travel Directions
The Leiden Institute of Physics (google maps link) is located in the Oort and Huygens buildings, which are connected by a glass corridor. These buildings also house the Leiden Observatory and the Lorentz Center for international workshops.

Route planners 
For route planners and navigators, use the address Ehrenfestweg. After turning into Ehrenfestweg, the parking lot is on the left. 

Travelling by car on the A44 
Get off at the exit Leiden, and drive towards Leiden. Take the first exit on the left, this is the Ehrenfestweg. The parking lot is the first to the left.

Make sure you take the A44, not the A4 which also connects Amsterdam, Leiden and The Hague, but runs along the other side of the city.

Travelling by car on the A4
Get on the A4 direction Leiden. Take exit 6a Zoeterwoude-Dorp and Leiden. Turn left on N206 to Leiden Voorschoten. Then continue to follow N206 towards Leiden-Zuid and Katwijk. When there is a Bastion Hotel at the left, N206 turns right (Leiden-Zuid, Katwijk). After about 3 km, N206 turns left (Amsterdam, Den Haag). Leave N206 and continue straight ahead into Ehrenfestweg. The parking lot is the first to the left.


At the parking lot, announce your visit to the operators (if possible, have your host arrange a spot). After parking, walk toward the Oort/Huygens building crossing the bridge, and following the path. Please report to the reception upon arrival to obtain a parking permit for the duration of your stay, or arrange beforehand with the person you are visiting.

By bicycle
It's about a 15 minute bike ride from Leiden Centraal station (ov fiets members can rent a cheap bike there). The simplest route (2,2) km is over the Wassenaarseweg, take a left just before the flyover.

-30, 31 or 38 bus to Katwijk (get out at Bio Science Park-Oost)

-43 but to Den Haag via Wassenaar (get out at Universiteitsterrein)

By taxi
Taxis are located on the front side of the station, on your left-hand side. Use the regular taxis rather than the trein-taxi. It costs about 15 euros and 10 minutes to get to the Leiden Institute of Physics.
