What climbers say again and again
“It was so nice to not have to set up or clean up after the party and took away all the party planning stress from this busy boy mom.”
“My daughter is naturally cautious, so I loved that she felt comfortable enough to try everything in the gym.”
“We’ve participated in open gym, classes, camps, ninjas night out, and have had two birthday parties at Ultimate Ninjas Academy and every experience has been exceptional!”
“The coaches all provide such a welcoming, supportive environment for kiddos to try new things and most importantly, build their confidence as they do.”
From the reviews
We originally went to Ultimate Ninjas Academy Naperville to burn off some energy during the cold winter months, but what we found was a second home! Our kids (3, 5 and 6 when we started) have built confidence, body awareness, overall body strength, resilience, determination and so much more from attending ninja…
I can’t say enough great things about Ultimate Ninjas Academy! The entire staff is upbeat, positive, and incredibly attentive to the children — you can really tell they love what they do. The energy in the gym is always fun and encouraging, and the kids leave feeling proud and confident.
We recently had our son’s 3rd birthday party here and it was such a wonderful experience! Melissa was great during the booking process and coordinating with us the week of to make sure we had everything we needed.
I cannot overstate how great Ultimate Ninjas Academy is! I took my 6 y/o for a class, and I loved watching the coaches gently instill confidence in each kid, showing them that they’re capable of doing more than they imagine.
Birthday parties at Ultimate Ninjas Academy Naperville
Ultimate Ninjas Academy Naperville hosts birthday parties — confirmed on their own site. Climbing parties come with staff who handle the harnesses and belaying, so parents can mostly watch. One thing that's different here: every guest needs a signed waiver — send the gym's waiver link to the other parents when you send invites, or check-in day gets slow. Packages, party rooms, and pricing change often, so check the current options and book ahead — weekend slots go fast at popular gyms.
Kids classes & camps at Ultimate Ninjas Academy Naperville
Reviews and the gym's own info mention kids programs at Ultimate Ninjas Academy Naperville — climbing classes, school-break camps, or a youth team where kids learn technique from coaches instead of just scrambling around.
