Pomona sits in the eastern San Gabriel Valley where summer temperatures routinely top 100°F, making splash pads a practical necessity from June through Labor Day. The city itself has free options, and the broader region — stretching toward Rancho Cucamonga and Orange County — adds a strong mix of free neighborhood pads and a full-scale regional water playground. Most are a short drive from anywhere in Pomona.

Pomona Splash Pad Checklist
- Two towels and a dry change of clothes per kid: wet swimsuits on a hot car seat are miserable.
- Water shoes: rubber soles grip wet concrete; bare feet burn on pavement between jets.
- SPF 50+ sunscreen, applied 15 min before arrival: Ganesha Park Splash Pad and most Pomona splash pads have minimal shade, so a portable canopy extends your session past midday.
- Your own water bottle: splash pad water recirculates through a filtration and chlorination system and is not safe to drink, even when it runs clear.
Swim Diapers and Water Hygiene
- Swim diapers only for children not yet potty trained, regular diapers absorb recirculating water, swell, and can contaminate the shared system. Most municipal splash pads require them.
- Don't swallow the water: it's treated recreational water, not drinking water. Repeated swallowing can cause gastrointestinal illness.
- Rinse off after with soap and water. Keep kids with open wounds or a recent stomach illness out of places like Cucamonga-Guasti Regional Park Splash Pad, standard filtration doesn't remove all pathogens instantly.
