Meudon Observatory is located Place Jules Janssen , in Meudon at the top of the Avenue du Château.

There are many different ways to go there from Paris. They are described below, but you may want to see a map when coming from Roissy CDG airport or Orly airport.

By car there are 2 possible routes :
Take the périphérique, exit at Quai d’Issy, then go towards Issy les Moulineaux, Sèvres and finally Meudon Take N 118, from the Pont de Sèvres, going towards Chartres Orléans, exiting at Meudon Sèvres and then going towards Meudon

By train (French railways - SNCF) there are two possibilities :
At Paris-Montparnasse station, take the trains going to Sèvres Rive Gauche (every 15 min.) or (rarely) to Versailles-Chantiers, Rambouillet, Chartes, etc… Make sure the train stops at the Meudon or Bellevue stations (see below). Get out at the 3^rd station : Meudon (after Vanves-Malakoff and Clamart). Outside station, turn to the right, after 200 m turn again to the right then straight ahead up to the top of the hill along an avenue lined with stately chestnut trees. Or get out at the 4^th station : Meudon-Bellevue. Outside station, turn left on the avenue du Château : the entrance of the Observatory is on the top of the hill. The RER ligne C (suburban train system) : Take the train going in the direction of Versailles Rive Gauche and get out at the Meudon-Val Fleury station. Follow the direction of Meudon not Clamart (you’ll be better ask your way…) About a 15 to 20 minutes walk (climbing !).

Subway + bus :
Line 12 (Porte de la Chapelle-Mairie d’Issy). At the terminus Mairie d’Issy take the bus 169 direction Pont de Sèvres, stop at the Place Rabelais or Eglise de Meudon.

Don’t forget : the way towards the Observatory is always uphill, whichever way you choose.

Once arrived, use the map of the Observatory.
