Located on the western edge of Paris, the 845-hectare Bois de Boulogne was designed by Baron Haussmann, who was inspired by London's Hyde Park. While this park is a great place to relax and enjoy nature, it also contains an area, the allée de Longchamp, where sex workers are known to cruise for clients. For fans of horse racing, the Bois de Boulogne includes two tracks: the Hippodrome de Longchamp for flat races and the Hippodrome d’Auteuil for steeplechases.
