There are no animals at the Brooklyn Zoo, but there's plenty of Parkour.
Parkour involves moving quickly through vaults, jumps, and climbs.
Some say it's like skateboarding without the board.
Visitors have been flipping out at the Brooklyn Zoo since it opened in March on Bogart Street.
"We start you off with literally baby steps. And then from there, the more you progress the more we teach you, the more we can have you go to your full potential," said Brooklyn Zoo Co-Owner Geronimo Frias.
"I like Parkour and just doing different activities here because it's a really safe environment to practice it. And we have a huge variety of different obstacles. Like, you could basically practice whatever you want here safely. And we also have great instructors that help you throughout your whole time here," said Arthur Oldakowski, a Brooklyn Zoo student.
"This whole gym helps me with other sports to improve my flexibility and improving my athleticism. The instructors are great and anyone can really start and really take off here at the zoo," said Jared Barrett, a Brooklyn Zoo student.
The facility offers a range of classes, as well as day camps, and open gym hours.
