Tennis Luxembourg

You're more likely to be offered a place in the first round of Roland Garros than to get hold of one of the Jardin du Luxembourg's four tennis courts on a sunny Sunday. Its central location, scenic setting and relatively cheap cost ensure a steady stream of punters on weekends; in 2009, a group of savvy netizens even hacked the booking page on the council's website in order to guarantee themselves a spot. Whether you're willing to go to such lengths to play on the best courts in central Paris is down to your moral compass and technical know-how – but believe us, it's (almost) worth it.
