Way to paris selection center from paris airport 🇨🇵

You’ll need the following things:

• Take your bag and follow the exit signs
  

• Follow the RER B inscription (blue line)
  

• Buy a ticket at the station. I didn’t have my credit card so I asked a French guy to buy my ticket and I paid back him in cash. Price 10.30€
  

• Take the RER B and take off at “Chatelet-les-Halles”, the journey will take around 25-30 minutes
  

• Switch to RER A (red line) in the direction of “Boissy-Saint-Léger”, but you took off at Val-de-Fontenay. Good news, the you only have 2km left to reach the fortress.

• Look for “Avenue du Val de Fontenay” when you quit the station. You’ll see a big roundabout and continue straight ahead until you arrive on Boulevard Gallieni. Walk a few hundred meters and turn left onto “Impasse de la Croix Pommier” and you’ll see the fortress.

This is how I arrived to Fort de Nogent (and got lost as you can see in the first chapter). It’s much better if you previously downloaded the journey via Wi-Fi at home and just follow its instructions until you arrive at the base.
