About Us
Welcome to Kiddo Adventure. San Mateo’s ultimate children’s indoor playground, birthday party venue, and hub for kids’ get-together. We’re here to turn play into a full family experience, with party rooms, slides, obstacle courses, suspension bridge, log swings, zipline, role-play zones, soft play areas, and endless adventures waiting to be discovered. Our doors are open to provide a relaxed, welcoming “home” for birthday parties, celebrations, playdates, social connections, and community gatherings.
As one of San Mateo’s best indoor playgrounds for toddlers and kids up to age 10, our focus is on encouraging physical activity and supporting developmental growth, while helping families maintain a healthy balance with screen time. And we’re passionate about providing a clean, safe, and welcoming space where kids, families, and friends can enjoy active play and create fun memories together.
Come join us for a fun-filled experience at our adventure-packed indoor playground!
