It’s a Brooklyn Boulders birthday bash.

For the past two years, the urban jungle gym in Gowanus has been offering rock-climbing classes for all levels in garage converted into an alpinist’s Eden.

To mark its second anniversary, the space is throwing an off-the-wall bash on Sept. 10 which, if last year’s party is any indication, may go well past acceptable rock climbing hours.

“Last year, we threw a party and it went until like 3, 4 in the morning,” said manager Carlos Munoz. “We spent the whole night celebrating.”

At this year’s event, there’ll be activities for climbers of all ages, including zip line runs, treasure hunting, a cornhole tournament, a photo booth, and giveaways.

And of course, there’ll be rock climbing on the center’s 11,000 square feet of climbable wall, including a 28-foot replica of the Brooklyn Bridge’s iconic tower and walls as steep as 45 degrees for harness-less “bouldering.”

“Ninety-five percent of people like it,” said Munoz. “Once you’re here, you’re hooked.”
