Summer Camps

Looking for something AMAZING to offer your kids over break? Send them to Ultimate Ninjas Camps, where they will learn how to tackle obstacles as seen in the hit TV show American Ninja Warrior. At Ultimate Ninjas it's so much fun to get back up and try again.....

At Ultimate Ninjas, we instill self-confidence, acceptance, and a true hunger for tackling obstacles with a positive mindset. The best part: we have a BLAST doing it! The camps are designed by 3 time American Ninja Warrior Jesse Labreck, you will not find a more positive environment where kids can show up, be valued for exactly who they are, and discover what they are uniquely capable of achieving.

During camp, kids are grouped together by age and rotate through stations where they are coached on each obstacle. After learning how to tackle the obstacles, they have time for open play so they can pick their favorites and spend extra time on the obstacles they want to master or just enjoy! At the end of camp all kids will get a chance to run through the course with their coaches just like you see on TV!


$45 for your first session, each additional session for that week is $40 | 50% sibling discount

My family visited Ultimate Ninjas Libertyville for a birthday party. I was very impressed with the service, instruction, and attention the kids received while on the Ninja course. The birthday attendants kept close watchful tabs on the kids to ensure everyone's safety and got an ice pack for the birthday boy when he bumped his head. 40 minutes on the warped wall (several different heights), then 40 minutes on the Ninja obstacle course plus basketball and a fun game of dodgeball, and then 40 minutes in the party room. The attendants kept the kids busy on the obstacle course, were attentive and taught the kids the game of dodgeball, and were super helpful in helping with the party (carrying the cake to the table, passing out anything needed by the parents, and helped me take down decorations! I was very impressed with the service compared to other kids party places I have visited. I would hands down recommend this place for kids birthday parties! My kids loved it here! Make sure to check out the different walls throughout the facility with large photos of famous America Ninja warrior contestants and kids at the gym. Super cool place, for kids and parents alike!

What our customershave to say about us

We just threw my daughter's 6th birthday party here and it was wonderful! They were very helpful and accommodating. Our guests had a great time and the staff assigned to help our party could not have been nicer. I would recommend this for a party venue (or just a fun open play/class activity) to anyone!Hannah B.
I brought my 11YO son today for open gym and he absolutely loved it! It definitely became more crowded after 12:30, but the staff was great and offered assistance when requested. The obstacles were just like the show and are easy to try, but challenging to master. We will be back for sure!Amy J.
