Venue

The Meudon Observatory can be easily reached by Public Transportation.
We recommend therefore booking a hotel in Paris and commuting each day by train.

Here you can find a List of Hotels.

There are two possibilities to access the Paris Observatory by train. We recommend the first one.

1) Train

At Paris-Montparnasse station (SNCF : French railways), 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 3rd 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 4th station: Bellevue. Outside station, turn left on the avenue du Château: the entrance of the Observatory is on the top of the hill.

2) RER C

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...)

You can also use the online public transport journey planner.

Don't forget : the way towards the Meudon Observatory is always uphill, whichever way you choose. It takes about 15 to 20 minutes to go from any of the Meudon train stations to the Observatory.

Once arrived at place Jules Janssen, 92190 Meudon, enter the public park gates and turn right. Then, there is a small gate, just pass the green guard-post on your left (if they stop you, just say that you are a participant of the CIAS workshop 'Energy Cascade and Dissipation in Astrophysical Turbulent Plasmas’, normally they have a list of participants). Then you should go to the left toward the small "forest", follow the path and you arrive to green metallic stairs, go up, then you are on the level of the principal buildings of the Observatory. Just upstairs, turn left, and you arrive at the "castel", the place of our workshop. On the map of the Meudon Observatory, it is Bat. 9 (Chateau/Grande Coupole)

Inside the castel, follow the indication CIAS and/or 'Energy Cascade and Dissipation in Astrophysical Turbulent Plasmas’.
