We are a huge fan of Smithtown Ninja!!
Highly recommend.

Kathryn (the owner) is amazing. She has created an environment that is supportive & fun (for every level). They have professional coaches & they’re great with the kids.

My kiddo enjoys the weekly classes.

There are Winter, Fall & Spring semesters. (If you want to register after a semester starts - just call, I think you can start up until the 4th week of class).

In the summer they have their weekly classes or a summer camp option.

There’s also the special event “fun run” which is a full course for the kids to go through.

The facility is clean!! They have a nice sized Birthday Party room, too.

Definitely check out Smithtown Ninja - I highly recommend!

Editing to add:
My kiddo had his Birthday Party there this year and it was SO much fun!

The instructors were amazing, as usual, and even though we had so many kiddos with different skill levels, they all did great! I brought decorations and they totally set it up while I enjoyed the party and let one parent around the ninja area to take action shots of the kiddos (the other parents could watch or relax in the "parent area"). The party room was super clean and the instructors totally took care of the kids while I ate & enjoyed the party!

Yes, I definitely recommend their birthday parties, too!

My son loves coming here. We registered him for a 4 week summer program to see if this place was a good fit for him and we're definitely signing him up for the 12 week program this Fall!

I had my son’s 7th birthday party just today and had to get on to write this review immediately! Smithtown Ninja is the place to be. From the moment we arrived until we left, Kathryn and her staff took care of EVERYTHING. They were so great with the kids and had smiles on their faces the whole time. You can tell they all genuinely love what they are doing. My son and his friends didn’t want to leave. This place is so cool- even the parents wanted in on the action! If you are looking for a place that is different from all of the other birthday party spots, look no further!! You will not be disappointed! Thank you Kathryn and the Smithtown Ninja Staff for making my son’s birthday one we will never forget!

Just had my son’s 8th birthday party and was super impressed. All the kids had a blast and the staff was so professional. Looking forward to signing my son up for classes.

We can’t recommend Smithtown Ninja Academy enough! Our daughter is not a sports kid and has always agonized over PE in school. I was concerned this would be too difficult for her, but she is loving Ninja class and always leaves class with a smile! All the coaches are so encouraging, and each child gets individual attention to meet their skill level. Best class she’s ever taken!

The best place to train on American Ninja Warrior style obstacles in Suffolk County with the only 18-foot wall on the Long Island. This facility is so fresh and clean! Birthday parties and team building events are so much fun here!!! Adult nights, too!!!

Didn't know what to expect going in the first time, and was surprised to see the size of the facility and how they were able to create so many obstacles! On top of that, the staff was so sweet and made it an amazing time! The classes are amazing because you can be challenged or accommodated, so no matter your fitness level- you will feel comfortable and enjoy it!
It was so great that I decided to stick around permanently haha!

We had my daughter’s 8th birthday party here and it was fabulous!! The kids all had a great time. The entire place is extremely clean and the staff is wonderful. They are very accommodating and go out of their way to make the party special. Highly recommend for birthday parties, or even if you are interested in their classes. Would definitely consider for my son’s birthday party too.
Thank you Kathryn!!

What an amazing place. Classes are lead by knowledgeable instructors who seem to really care about the kids. Kids learn functional fitness while having tons of fun. Equipment is clean, well maintained and many options for kids of all sizes. I imagine with all this equipment it would be great for adults who have ninja and fitness ambitions, or who want to just have fun trying something different. Highly recommend.

Had an incredible experience at Smithtown Ninja Academy for our son’s 6th Birthday party. Kathryn and the staff are amazing to work with and the kids all have the best time! Reserving and scheduling the party was so easy and Kathryn communicated with us the entire time to make sure everything went smoothly. The day of the party, they took care of everything, were so patient with the kids, and made sure they all had fun and were safe. The other parents could not stop talking about how cool it was!

The gym itself is so impressive and everything is brand new and clean. We will definitely be back with our son and I may even look into trying it out myself!

100% recommend this place to everyone. Check it out!

What an awesome birthday party experience for our 10-year-old. Facility is cavernous and clean with a variety of apparatuses, and the coaching staff was extremely upbeat as the kids took on new challenges. One went home and said “let me tell you how cool this place is!”—they were into it! It would be cool to allow each kid to try an obstacle course—food for thought!
