Attended the Tuesday open gym as a surprise date night that my wife planned. I regularly do parkour and loved to train for Sasuke when I was younger. I had never been to a real ninja warrior gym but it exceeded expectations. The staff was extremely welcoming, the space was clean and had a ton of challenges that I've seen on TV but never had the chance to get my hands on. There is also a bouldering wall and a trampoline with a foam pit. I'll definitely be recommending it to anyone intested in ninja warrior challenges or just a fun place to play around and use your body!
Just like the real thing on the show Ultimate Ninja Warriors. This gym and the staff are amazing; our son loves it here and the skills he has learned are amazing. Highly recommend

This place is amazing and great for the kiddos. 2nd time there and brought three 11 year old girls and one 7 year old girl. They had a blast. I think the hide and seek during camp was a big highlight. Paola took great care of us and Mike “The Stallion” Silenzi was great. Cannot recommend enough.

Our little one has been doing Little Ninja classes since he was about three. We have had the BEST experience.

The coaches are amazing, especially Coach Pao. They are so invested in and supportive of the kids, and when the kids achieve a new milestone, like conquering the warp wall, the coaches celebrate alongside them.

The courses are always changing and challenging, and have done so much for our little one's agility, balance, confidence, and stamina. I love knowing that my little one is burning off some extra energy and developing a love of exercise. I also appreciate that the facility is always clean!

10/10 recommend!

Our toddler was able to go out and play for an open gym and we had an absolute blast! He struggles with muscle tone and we work with him through OT we were delighted to see so many of the same activities readily available here.

His absolute favorite was the little zip line and the ramp to run up and touch the button.

I highly recommend taking classes and trying open gym. Great for littles as well as big kids!

Went here with my daughter for a birthday party. Loved that they closed off half the gym at a time so kids had privacy and space to enjoy everything. The staff was great helping kids reach things and explaining what to do on the equipment.
Top notch facility. Super fun for the kids. The owner is suuuuuper friendly and checks in periodically. I couldn't say enough good things about this place. Priced affordably, clean, the list goes on

We had a large birthday at Ultimate Ninja for my 6 year old today and it was absolutely amazing. The staff were so helpful and very welcoming. They were wonderful accommodating all our needs. Our guest list ranged from 6 to 17 and everyone had a blast. Even the adults participated and loved it so much. I highly recommend this place. Definitely looking into the classes they offer.

We visited for the first time Friday night to check out open gym and came back Sunday morning again. My son is obsessed and keeps asking to come back. Perfect for an active kiddo. I was impressed not only by the facility itself but also by how welcoming some of the “regular” kids are. Both days there were older kids who clearly visit regularly helping my son climb the walls and then playing with him. We will definitely be back and are considering this location for a birthday party spot. I am also thinking about getting my son signed up for a class since he loves it so much. My only suggestion would be to maybe give a tour to newbies- I can see how this place could be intimidating to some! There is so much to do!

We went to a birthday party at Ultimate Ninjas in Oak Creek today and it was an amazing experience! The kids had an absolute blast! There are so many fun obstacles and activities for every age! We will definitely be returning here again and will sign up for some of their classes too! If you are looking for a unique, fun and exciting place to take your kids this winter or need a cool place to host a birthday party, this is a great choice! Definitely recommend!

We celebrated our son’s 7th birthday at Ultimate Ninjas in Oak Creek, and it was an incredible experience! The staff was friendly, organized, and great with the kids. The facility is top-notch, with fun, challenging obstacles that kept everyone engaged and having a blast. The party setup was seamless, and they made sure everything ran smoothly from start to finish. Our son and his friends couldn’t stop talking about how much fun they had. Highly recommend Ultimate Ninjas for birthday parties or just a fun day out. Thank you for making our son’s birthday unforgettable! You guys rock!

Absolutely LOVE this place and so glad I found it.. my kiddo is 5 years old and he's now addicted to the classes. It helps build his muscles and his confidence!! 20.00 a week for 5 year olds and 25 a week for 6 up is a great deal. Mike (the owner) was an actual "Ninja Warrior" and has made it to the finals multiple times on the show.. Watch season 14, episode 8 (currently on Netflix).. He is the first person on that episode. He's the real deal and designs all the classes.

My son Charlie is 3.5 years old and loves Parkour and ultimate ninja warrior which makes life challenging to try and support this way of life for him. Little ninjas class has been absolutely incredible for him! I have never seen him more engaged and excited about any other sport/activity we have signed him up for. Coach Paola is absolutely amazing! My son literally loves her and talks about her all the time. She has such patience and motivates toddlers to focus and keep trying which as a mom of a toddler, I can tell you that that is no easy task with 1, let alone a whole class! Coach Mike is always so kind and encouraging every time we come into the gym as well! If you are looking for a new activity for your high energy physical child, look no further! I cannot thank you all enough for giving Charlie a place to reach his full ninja potential! 💪🏼✨

We just celebrated my son's birthday at Ultimate Ninjas Oak Creek. The kids had a blast! The staff was attentive and involved in coordinating the supervised open play. The facility was clean and the communication and check in process was smooth. We would 100% recommend this location for any parents considering having a birthday party here.
Exceptional faciliity! Just like American Ninja Warrior. Obstacles are well designed for all ages. Activities are fun, safe, and challenging. My kids love it! We drive over 30 minutes and it's worth it!

We attended a birthday party and it was great! We were in the little ninja area and the kids were fascinated by the warped wall with the slide. Pizza was delicious and the staff was very friendly!!

If you're looking for an active field trip for kids who love to climb and try new things, this is 100% the place to go to.

Brought my class here on a field trip all the way from Madison and I can say it was for sure worth the trip! Mike, Nathan, and Marquez made sure my class had an amazing time on all of the ninja equipment while also making sure the kids were safe on new obstacles. They even provided us a room for lunch and to keep our things in.

Thanks guys!

We switched our two girls to Ultimate Ninjas Oak Creek from a gym in Hartland we had been at for a couple of years. It is a little longer drive, but it is easily worth it! The staff is very encouraging, the obstacles are super fun and the classes are well structured. Ninja is a great sport for kids of all ages, and Ultimate Ninjas is the place to do it.

We had the honor of being the first party that they hosted. My daughter’s 7th birthday party was amazing! Mike followed up before the party to confirm everything and answered all of our questions. The staff was so awesome! Marquez and Nathan (as well as another young lady) interacted with all of the kids. They were very involved in assisting us with the set up of the room (we had themed tablecloths and balloons), pouring drinks, passing out pizza and cupcakes. They even stayed and sung happy birthday. It was truly a great experience that you won’t get anywhere else. You can tell everyone truly enjoys what they do. We will definitely return back, especially to check out those Ninja classes. So what are you waiting for??? Book today!!

We had the best experience here today! The staff member working in the little kid area was awesome. She was super helpful and encouraging to both of my kids (2 and 5). I chatted with the owner a bit about the classes and he was very friendly and informative. We’ll definitely be back!
