Sunnyvale gets hot in summer and the Bay Area fog doesn't always cooperate on the inland side — which means a splash pad can go from "optional" to "necessary" faster than you'd think. Sunnyvale has several seasonal spray parks right in the city, and within 14 miles you've got the Hellyer County Park splash pad that gets consistently ranked among the best in the South Bay after its $6.5 million renovation. All five picks run on roughly the same April-to-October schedule and they're all free or under $7 to enter. Here's what's worth loading the kids into the car for near Sunnyvale.

Location: 1010 Morse Ave, Sunnyvale, CA 94089
Sunnyvale👶 Best for all ages💲 Free🚗 2.3 mi
A pirate ship playground with a free seasonal spray pool — Sunnyvale's most rated splash stop: Seven Seas Park is consistently the splash pad Sunnyvale parents recommend first, and the reason is that the water feature sits next to a genuinely fun pirate-ship-themed playground, which means kids who aren't ready to get wet yet have something to do while siblings do.

The South Bay's most talked-about splash pad — part of a $6.5M playground renovation at Hellyer County Park: Hellyer County Park's splash pad is built into a rock-formation theme with water jets, waterfall features, and ground sprinklers arranged so that kids can move through it at their own pace — walk to the edge and get misted, or stand in the center and get completely soaked.

The $6 vehicle entry fee covers the whole park, which includes the 30-foot play structure right next to the splash pad and a toddler zone with its own sand play and musical tiles.

How we picked these
We picked these based on what parents actually care about at a splash pad: whether the water feature is the real thing (not just a decorative fountain), whether there's shade and restrooms nearby, and whether the experience holds up for multiple age groups at once. Research draws on city parks data, county parks pages, and parent reviews from across the South Bay. No paid placements.Planning your visit
All five splash pads in this list run approximately April through October — some start as early as March 15 if temperatures cooperate, and a few run into late October. Hours are typically 10am to 6pm for the city parks; Hellyer County Park's splash pad runs during park hours with the same seasonal window. The city parks (Seven Seas, Magical Bridge Fair Oaks) are free; Hellyer and Jack Fischer require a quick drive to Campbell or San Jose but add the bonus of a full park experience around them. Call ahead if you're making the trip specifically for water play — closure for maintenance can happen without much notice.

Sunnyvale 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: Magical Bridge at Fair Oaks Park — Water Play Zones and most Sunnyvale 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 Seven Seas Park Splash Pad, standard filtration doesn't remove all pathogens instantly.
