Birthday Parties

Party Time!

At Gymja, we know how to throw a Birthday Party! Fun but challenging obstacles, exciting Ninja Warrior courses, and the bounciest trampoline you’ve ever seen will leave you and your guests talking about this party for years. Our enthusiastic party staff are there to teach, ensure safety and make this the easiest party You as a parent have ever thrown. (Parties for kids 6+ unless currently enrolled in our Little Ninjas program.)

For the best understanding of how our parties operate and what to expect, read through this entire party page AND/OR head into the gym (during our set class hours Mon-Thu after 3pm) and ask one of our coaches to give you the full run down. Parties are held Fri, Sat and Sun.

“This is the second year in a row that my son has had his birthday party here and the staff are amazing! They tailor the party to the ages attending, keep the kids engaged, and make sure everyone has a blast! Add in the fact that as a parent you only have to bring the cake and drinks while they take care of the rest, it the perfect recipe for all! My son is already asking to go back to open gym or to take a class!” –Allison, Topsfield MA

All Parties include:

-Gym Time: This is where the party happens! Free play at the beginning, instructed obstacles time, and awesome ninja courses are the bread and butter of our birthday parties. If there are any special requests, let us know beforehand so we can set it up! (gym time varies by party package)

-Party Room Time*: At the end of your allotted gym time, you’ll get 30 minutes in our closed off party room for food, drinks, and cake!

-Gymja T-Shirt: The Birthday guest of honor gets their own Gymja Warrior T-Shirt. (Ask the staff the day of your party to see the different types of shirts we have in stock)

-The Ease of a Gymja Party: Our party staff is there to teach/monitor the kids during the party so you can sit back, relax, and take all the pictures you want. (Kids under 5yrs should be accompanied by an adult during the party) We provide the table cloths, napkins, cutlery, and candles. (Feel free to bring your own if you have a certain theme for your party) There is a fridge and freezer in the break room if you need anything to stay chilled. And lastly, we will do the clean-up, making this the easiest party you have ever thrown!
