By public transportation
Travelling by train, tram or bus to The Hague Central Station: leave by the side entrance on Platform 12 (signposted Randstadrail). Go straight ahead and you will see the entrance to the National Library of the Netherlands (the KB Building). The RKD is situated on the ground floor. Lockers are available under the entrance hall.
Please note that the above situation may already have changed again by the time you visit us: The Hague City Council and Netherlands Railways are currently undertaking major building work which is likely to continue for some time.
