If you're visiting Paris this summer, consider packing a picnic basket. As Travel + Leisure reports, city officials will launch a two-month initiative in July to keep 16 of the metro area’s largest parks and gardens open 24 hours a day.

Called "Les Jardins Nocturnes" (the Night Gardens), the event will run from July 1 through September 3. Nature lovers can enjoy moonlit green spaces like the Parc des Buttes Chaumont—which has a Roman temple replica perched atop a cliff, overlooking a man-made lake—and the sweeping green lawns of the Parc Montsouris in the city’s 14th arrondissement.

More than 130 of Paris’s smaller parks and gardens are already open to the public during the evening. Once Les Jardins Nocturnes begins in July, nearly half of all of the city's green spaces will go 24/7. According to officials, the seasonal initiative is intended to help Parisians enjoy the city’s natural attractions after work, and take summer strolls during the cooler evening hours.

City parks aren’t always the safest places at night, which is why security teams will be deployed to keep an eye on late-night patrons. But while you're embarking on evening nature excursions, make sure to mind your manners: In 2016, Paris launched a similar parks program, and nearly 700 residents near the Parc Montsouris signed a protest petition complaining about excessive noise and litter.
