Bonita 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 — Sweetwater Summit Regional Park Splash Pad and most Bonita 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 Millenia Stylus Park — standard filtration doesn't remove all pathogens instantly.
