San Dimas is best known for the water slides at Raging Waters, but that's a paid amusement park, not the kind of free afternoon spray session most families are after on a random hot Tuesday. The city's own parks lean on trails, an equestrian arena, and a dog park rather than a splash pad, so the closest free options are just a few minutes over the city line in Pomona, Covina, and Azusa. Here are the best ones within a short drive of San Dimas.

Most of these splash pads run seasonally from Memorial Day through Labor Day, generally late morning through early evening, and hours can shift with staffing, so it's worth a quick check of each city's page before you drive over. Mornings are the most comfortable time to go once the inland heat sets in during July and August. Bring swim diapers for toddlers and water shoes since the pavement heats up fast in direct sun.For more kids' events near San Dimas this week, see the San Dimas events page.
San Dimas 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 San Dimas 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 Cougar Park Splash Pad, standard filtration doesn't remove all pathogens instantly.
