But don't take our word for it. We are the best place to have a ninja warrior kids birthday party in the Hagerstown, Greencastle, and Martinsburg area. Here are some reviews from previous birthday parties at 4 Star Obstacles:


Jessica says:   “I had my son’s 7th birthday party here. The staff were attentive and awesome with the kids. The all around vibe of the place was fantastic. It was well organized and I really appreciated being the only group in there; the kids didn’t want to leave! I would highly recommend 4 star to anyone!!”

Scott says:   “Granddaughter’s 9th birthday party…10 girls and they all loved it !! Excellent staff..very attentive and aware of individual needs and abilities.. challenging but adjusted to age..give them an experience to remember…highest marks”

April says:   “My daughter just had her 7th birthday party here and it was awesome! The coaches were so helpful and attentive. Every single kid had a blast and is ready to come back. I would highly recommend 4 Star Obstacles if you are considering this venue for a birthday party!”

Preparing for the party

Please arrive 15 minutes prior to the party. Participants will need tight fitting shoes and comfortable clothing. New Balance typically has good grip if your looking for a ninja shoe.
