Santa Rosa summers regularly climb into the 90s, and the city has stepped up its water play game with a brand-new spray park at Finley Aquatic Center and the long-running free spray ground at Prince Gateway Park downtown. Spring Lake adds a splashy inflatable water park option for older kids, and Petaluma has a solid splash pad if you want to make a day trip of it. Here's where Sonoma County families go to cool off.

Downtown Santa Rosa's go-to free splash spot is Prince Gateway Park's spray ground. The half-acre park offers cool water spraying down for kids of all ages, open daily 11am to 6pm from May 23 through September 7. It's compact, so pair it with a nearby playground if the kids want more to do.

2. Finley Aquatic Center Spray Ground (Santa Rosa)

Location: 2060 W College Ave, Santa Rosa, CA 95401

Santa Rosa👶 Best for ages 2-17💲 $🚗 1.7 mi

Finley Aquatic Center opened a brand-new spray ground in June 2025 with 15 interactive water features, from mild dripping palm trees for the little kids to a 10-gallon Sky Soaker that dumps a genuinely huge splash on anyone standing underneath. Admission is included with regular Recreation Swim pricing ($4-$5), and the tropical-themed landscaping with palm trees and two shaded picnic areas make it easy to plan a full afternoon. It opens daily at 1:30pm through summer during Recreation Swim hours.

Parent tip: Get there right at 1:30pm opening if you want first pick of the shaded picnic tables before they fill up.

3. Spring Lake Water Park (Santa Rosa)

Location: 393 Violetti Rd, Santa Rosa, CA 95409

Santa Rosa👶 Best for ages 5+💲 $🚗 4.2 mi

Spring Lake Water Park is a different kind of water play: an inflatable, floating obstacle course on the swimming lagoon at Spring Lake Regional Park, with slides, climbing walls, bridges, balance beams, and an in-water sports court. It's built more for kids who can swim confidently than toddlers, runs Memorial Day through Labor Day in four daily sessions, and costs $10 to $14 per session. It's a great add-on if the kids want more of a challenge than a standard splash pad.

Good to know: floating water park, slides, climbing walls, lifeguarded, lagoon.

Parent tip: Sessions sell out on hot weekends, so book ahead online rather than showing up and hoping for a spot.

4. Leghorns Park Splash Pad (Petaluma)

A genuine about 23 min drive each way from Santa Rosa, worth it if the kids need serious space to roam.

Location: 690 Sonoma Mountain Pkwy, Petaluma, CA 94954

Petaluma👶 Best for all ages💲 Free🚗 15.6 mi

Petaluma's Leghorns Park delivers a free splash pad plus playground and picnic space, about a 20-minute drive south of Santa Rosa. No fee, no reservation, and enough grass and shade to make a full afternoon of it.

Good to know: splash pad, playground, picnic areas, free entry.

Parent tip: Combine it with a stop in downtown Petaluma for lunch since it's a short drive from the historic district.

5. Ridgway Swim Center (Santa Rosa)

Location: 455 Ridgway Ave, Santa Rosa, CA 95401

Santa Rosa👶 Best for ages 4+💲 $🚗 1.3 mi

If your kids are past the splash-pad stage, Ridgway Swim Center's water slide gives them something bigger to aim for. The 48-inch height requirement limits it to older kids, but the rest of the pool is open to all ages during recreation swim. Entrance fee is modest.

Good to know: water slide, public pool, swim lessons, restrooms.

Parent tip: Check the recreation swim schedule before heading over since pool hours rotate through lap swim, lessons, and open swim throughout the week.

How we picked these

We looked for real water play open to the public, whether free or paid admission, and skipped anything private or members-only. Shade, restrooms, and nearby picnic space counted in a park's favor. Picks reflect what's actually operating this season, not what's planned or under construction.

Planning your visit

Sonoma County's splash season generally runs Memorial Day through Labor Day, with Prince Gateway Park's spray ground specifically scheduled May 23 through September 7 this year. Afternoons in July and August get hot and dry, so bring sunscreen and water shoes, and check each facility's hours since a few only run water features during specific swim sessions.

Santa Rosa 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: Prince Gateway Park Spray Ground and most Santa Rosa 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 Finley Aquatic Center Spray Ground, standard filtration doesn't remove all pathogens instantly.
