FURTHER INFORMATIONS :
L’accès piéton à l’Observatoire s’effectue par la place Jules Janssen: en principe, il y a un gardien à l’entrée. Sinon, il faut prendre une petite porte à droite de l’entrée principale, avec un digicode: 2009 + touche triangle.
L’accès en voiture s’effectue par le 11 avenue Marcelin Berthelot (la rue qui part dans la forêt de Meudon); là il y a toujours un gardien.
