March yourself to Velizy-Villacoublay Air Base, tour the site and try to understand what being a member of the military feels like.
This military installation is often on the itineraries of visitors to Bievres. But Velizy-Villacoublay Air Base isn't the area's only highlight. Palace of Versailles, Parc des Princes and Aquaboulevard are some other worthwhile sights close by.
