Spa day… but make it kid-proof. Spa Castle in Queens’ College Point, the famously over-the-top, five-story, hydrotherapy-filled funhouse, just added a new twist: Kids Castle, an indoor play zone designed exclusively for ages 5–10. That means that while adults soak, steam or nosh on dumplings between saunas, the little ones get their own kingdom.
Kids Castle lives inside the same sprawling complex known for everything from neon-lit saunas to year-round outdoor pools, but the new play area taps into a sense of surreal delight, swapping hydrotherapy for hands-on workshops, cozy lounge corners, interactive games and plenty of energy-burning activities. Kids get a full afternoon of fun and parents get permission to disappear into a whirlpool without guilt.
It’s a clever expansion for Spa Castle, which already draws a wildly mixed crowd of everyone from frat bros and couples to aunties who take their sauna rotations seriously—and has quietly become one of the city’s most talked-about daycation spots. The original Queens location sprawls across multiple floors, with separate nude bathing areas on the first level and coed water parks, themed saunas and a Korean restaurant upstairs. Families have long treated it as an all-day outing, so now the venue has officially leaned in.
Spa Castle’s full amenities remain in play for grown-ups: seven themed saunas, shiatsu massages, outdoor hydrotherapy pools and a classic, meandering vibe that makes every visit feel slightly chaotic in the best possible way.
Now, with a dedicated indoor haven for kids, the spa might have achieved the unachievable: a genuinely relaxing family outing where nobody gets bored and everybody gets to unwind—just not necessarily together.
