Coming from Utrecht, on the A27 (direction Hilversum), take exit 32 towards Bilthoven. At the end of the exit, follow the signs Bilthoven (do not follow the signs Groenekan) and after about 1 km (past the petrol station), turn left onto the Prinsenlaan. Many navigation systems do not recognize the Prinsenlaan in Groenekan. The Prinsenlaan is located between Nieuwe Weteringseweg 107 and 139.
If you come by bus, please take bus 55 and get off at stop Nieuweweteringseweg. From here, it is a walk of about 10 minutes.
