House of Sports – Ardsley
Choose from soccer, baseball or football at the House of Sports’ indoor 5,000-square-foot turf field, with spectator seating so parents can watch without getting whacked. There’s also a basketball option for parents of hoops fiends—nets can be lowered for the younger ones—as well as a paintball option. The facility’s coaches will help organize your child’s friends into games and activities. If that isn’t enough, you can also tack on a bouncy house, slide or a Gaga Pit for an extra fee. Parties are 90 minutes long: one hour to play and one hour in the private party room. Pizza and paper goods are included, but you bring the cake. 

Great Play of Scarsdale – Scarsdale
This 3,000-square-foot indoor turf field features projectors to bring interactivity to the activities. For example, they can set it up so your child feels like he or she is entering a stadium, complete with cheering crowds and scoreboard portraits, when the party kicks off. These parties are geared toward children up to age 10. Parties are 90 minutes long.
 
OnTrack Sport Center – Tarrytown
This facility has a whopping 26,000 square feet with indoor turf fields and batting cages. As with the other indoor fields, OnTrack offers the choice of including a bouncy house at the party for an extra fee. Speaking of fees, OnTrack attempts to keep costs lower than some of the other indoor arenas by segmenting its offerings. A “Coach Coordinator” isn’t included in the fee, but you can add one in if you wish. Likewise, you can either make use of OnTrack’s food or you can bring your own. Overall, though, even the most bulked-up package still comes in lower than several other places on this list.

Solaris – Yorktown
Children ages 4 to 13 can have a party at this sports club. These parties are (mostly) all-inclusive and come with pizza, cake, paper goods and activity coordinators. Guests can play team sports like soccer, basketball or whiffle ball, as well as playground games like dodgeball and red light, green light. There’s also a dance party option for an additional fee, and this is one of the few indoor facilities that has a tennis option for your little Serena or Andre.

The Cliffs – Valhalla
Young climbers can scale the walls at The Cliffs, an indoor rock-climbing facility. These two-hour packages include use of a party room, and you can bring your own food or use theirs for an additional fee. The staff will control the ropes—there’s a 1:5 ratio for staff and kids—so climbing experience isn’t required for your guests.
