Read more about this location
Kiddo Adventure is a downtown San Mateo indoor playground built as both an everyday open-play option and a full-service birthday venue. The space mixes slides, obstacle-style climbing, ball pits, role-play areas, and soft play with a polished look that feels more destination-worthy than a basic playroom. Daily walk-ins are welcome, but the venue also supports memberships, advance ticketing, and a detailed party program with hosts, themed room setups, and semi-private or more private formats.
