From Leiden Central Station it's only a 5-minute bike ride or a 20-minute walk to the Old Observatory. If you are coming by car, it is best to park at the carpark 'Haagweg'.
Due to construction, the Old Observatory can currently only be reached by foot or by bike. You can access the alternative routes through the Keizerstraat and the Zegersteeg (see the map drawn below). If you are unable to access the Old Observatory by foot and require assistance, please do contact us in advance at firstname.lastname@example.org
