About
Kiddo Adventure Indoor Playground in San Mateo is one of the most spacious indoor play facilities on the Peninsula, featuring a two-level climbing and play structure, slides, ball pits, sensory play areas, and a dedicated infant and toddler zone all under one roof.
The scale of the facility is its defining feature: rather than a single main bounce house or a small padded room, Kiddo Adventure provides enough variety — and enough square footage — that kids genuinely explore and discover for the duration of a 2-hour visit. Older kids gravitate to the upper level climbing structures and slides, while toddlers and babies have a gated zone at ground level where they can move freely without the risk of being knocked over.
For parents, there's a notable quality-of-life feature: a café area where adults can sit with coffee and still see the entire play floor. This is the kind of thing parents notice and tell other parents about — being able to stay present without being physically on the ground for two hours.
Kiddo Adventure is a popular birthday party venue; weekend party slots book up weeks in advance. For weekday open play, walk-ins are generally welcome. Located off 31st Avenue in San Mateo, it's accessible from throughout the Peninsula and close to Highway 92.
