The experience is available through a lottery run by the Parks Department, with about 900 to 1,000 people selected each summer to camp in participating parks.
Campers don't need to bring a tent. Parks staff set up the campsites, build campfires, lead nature walks and provide s'mores.
"We build a fire, we bring the s'mores, we take them on a nature walk at night and we tell them a scary story," NYC Parks Ranger Alex Pressman said.
The campfires are started without matches, a demonstration Pressman said often surprises both children and adults.
Participants only need to bring bedding or a sleeping bag. The rest of the camping experience, including the tent, is provided at no cost.
"We will provide the tent for you. You bring bedding or a sleeping bag and you have this incredible experience for free," NYC Parks Commissioner Tricia Shimamura said.
Rangers stay on duty throughout the night to supervise the campsites and ensure campers' safety.
"We're up all night with you. We're not allowed to sleep. We're on duty, so we're keeping an eye on things and keeping everybody safe," NYC Parks Ranger Ginny Renjilian said.
Public restrooms are also opened overnight for campers.
The program takes place at several parks, including Inwood Hill Park, Central Park, Marine Park and Alley Pond Park.
Officials said the overnight camping program offers participants a unique opportunity to experience New York City's parks after dark. Participation is free, but campers must be selected through the NYC Parks lottery.
