Ninja Camp is Cool!
Ultimate Ninjas Camps are designed to keep kids active, energized, and moving during their school breaks. Our ninja camps offer a structured, supervised environment away from the classroom that helps children grow socially and physically. Rather than sitting at home, children join a vibrant community of peers where they tackle exciting obstacle courses, build endurance, and channel their inner ninja.
Ninja Camps include:
- Obstacle Stations
- Trampoline & Foam Pit
- Games
- Arts & Crafts
- Open Play
Camps are designed for ages 5 -16.

AMERICAN NINJA WARRIOR -- "Baltimore City Finals" Episode 1110 -- Pictured: Mike Silenzi -- (Photo by: William Gray/NBC)
Mike is a 11 time American Ninja veteran and 7 time Las Vegas finalist. His nickname on the show is “The Stallion” and he can be seen on season 4, 5, 6, 7, 9, 10, 11, 13, 14, 15, and 16.
Michael grew up a competitive gymnast and by the age of 12 was ranked 37th nationally. In high school he made varsity as a freshman for pole vaulting and for fun was involved in a breakdancing group. He transitioned into ninja warrior training during college at Northern Illinois University where he earned his master’s degree in Physical Therapy. “I currently supplement my obstacle training with rock climbing and water sports including slalom skiing, bare-footing, and wake boarding.”
Michael hopes to grow the ninja community and promote the “NINJA LIFESTYLE” which involves being active, eating healthy, treating people kindly, and doing the right thing. “Competing on TV gives me a platform to be a role model. Whether I complete an obstacle or fall in the water I measure my success based on if I can make a positive difference in someone’s life.”

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.
