There is only one railway station in Warsaw Chopin airport? [12]
Very easy, especially if you have GPS.
If you're coming from Siemiatycze (lovely town) you'll either come the top or the bottom way (Wyszkow/Marki way or Sielce/Minsk way). Just follow signs; the roads are much better than they used to be 5 years ago thanks to the Nobel Prize-winning EU.
I don't remember any airport signs in the east of town, but they may well be there now. If not, the new outer ring road isn't complete yet so if you come the top way; you need to keep going until Trasa Torunska/Armia Krajowa becomes Prymasa Tysiaclecie and keep going until you see the airport signs near the turn off for Zwirki I Wigury. Basically anti-clockwise through the suburbs on one dual carriageway. If you come in the bottom way, just follow the dual carriageway clockwise round town, along Trasa/Lazienkowska until it becomes Armia Ludowa and you come to the same airport junction, at Zwirki I Wigury. From there, it's plain sailing.
Allow plenty of time for traffic jams, especially on Monday and Friday.
