They took the NYPD to new heights.

The three cops who announced in April their plans to climb Mount Kilimanjaro, the highest free-standing mountain in the world, to raise money for sick children have successfully completed their seven-day summit, The Post has learned.

The trio reached the 19,341-foot-high peak on Sunday, then descended the mountain in two days. They arrived at the “finish gate” at 9 a.m. Tuesday local time, said Lt. Manny Kwo, one of the three climbers.

“I can’t walk, but who needs legs?” Kwo, 33, quipped to The Post Tuesday, just hours after making it back. “It was great to be able to finish what we started despite the pain, the cold.”

Kwo, Lt. Charles Trento, 45, and Detective Nicholas Anastasakos, 40, embarked on the more than 19,000-foot journey to the top of the mountain in the hopes of raising $20,000 for the Ronald McDonald House New York, which provides care and a temporary stay for children with cancer and their families.

Trento concocted the plan after watching an episode of “The Ellen Show” and learning that actress Mandy Moore had made the voyage.

“It planted a seed. I was thinking, ‘We could do this, and let’s do it for charity,’ ” he told the Post at the time.

“It’s a chance to do something bigger than ourselves,” Anastasakos added.

The men have since surpassed their fundraising goal by more than $1,200, and the webpage to make donations is still open.

“Still too much to process but made it to the summit of #kilimanjaro,” Kwo wrote Tuesday in a post on his Instagram page. “Simply put, some of the most challenging 9 days of my life both physically & also mental but proud to check this one off my list and to do it with my fellow #nypd brothers, for the families @rmhnewyork battling cancers each & every day, priceless!”

He added: “I am forever changed.”
