Birthday Parties

Let Stamford Ninja Academy Host Your Next Birthday Party!

If you are looking for an entertaining kids party venue, Stamford Ninja Academy is the place to go in Stamford, CT. Our venue is just a short drive from the towns of Darien, Norwalk, Westport, New Canaan, and Greenwich. Our ninja facility offers a great alternative to home birthday parties! This means FUN for all the kids and less work for you! Your children will be challenged to an hour of fun ninja obstacle training with three of our professional ninja staff in most cases, and then a half hour for food and cake! If you are planning a birthday party for your son or daughter, we invite you to contact us and reserve your spot today!

Parties book up quickly so please book your party well in advance.

How It Works

  • Parties start at 6 years old, but all guests must be at least 5 years old to participate, and no older than 14.  We can comfortably handle a maximum of 27 participants, but can go up to 36 with additional staff.  You are the only people in the gym during your party.
  • During the 1st hour, your children will be challenged to fun obstacle training with our professional ninja staff. After the hour in the gym, you have 30 minutes for food and cake (you must supply the food and drinks). NO ONE is allowed back into the ninja area after the activities are completed. Piñatas and helium balloons are NOT allowed, sorry.
  • Parents are NOT allowed in the ninja area (on the mats) for safety reasons, but can watch from the bleachers and benches.
  • Presents should be brought home to be opened as there just isn’t enough time without shortening the gym time.
  • Gratuities are not included in the cost of the party and can be given directly to the instructors if you enjoyed the party.
  • For pizza, we recommend Bronx House at (203) 883-8883. Mention Stamford Ninja Academy for a $14.00 Large Pie (plus tax) with $2 toppings! They deliver too!!
  • Guest parents MUST fill out the waiver at the link below if they haven’t done so in the past year, please include with your invitation.
  • Please NO balloons or Pinata’s, thank you
