If your trip to Modlin Airport (WMI-Warsaw-Modlin Mazovia) is all booked but your itinerary is a little on the empty side, let us give you a helping hand.Take a little detour to Modlin Fortress and leave the airport behind. It's one of those sights you shouldn't leave off your itinerary. After that, head toward Saint Michael Archangel Parish, which is also worth a pit stop.
