An indoor urban park for children opened at Sunset Park over the holiday weekend.

Urban Air opened on Dec. 31, and owners estimated hundreds of people showed up in the first few days.

Some attractions at the park include virtual reality games, trampolines, bumper cars, jungle gyms and a ninja warrior training course.

"These cars spin and they flip," said owner Ari Moses. "They're getting loaded up right now. They spin and they flip, it's just a lot of fun." 

Moses estimates 1,000 people walked through the doors on Monday alone.

"It's been a whirlwind, there was a line around the block on opening day, it was amazing," he added.

Moses, who also owns three other Urban Airs in New Jersey, said the Sunset Park location was ideal to get families from all over the city to come.
