One of the most popular of Center City Philly splash zones is the Dilworth Park fountain at City Hall. Rows upon rows of water jets make a super-fun maze for kids (and their parents!) to run through. A public art piece is supposed to debut this July, too.

Sister Cities has two areas to relax and cool your jets. There is a "stream" fed pool to dip your feet in and there is the playful 10-spout fountain at the main entrance.

Francisville Playground became the first pool to participate in the city's Swim Philly program, which reimagines a select number of pools as engaging civic spaces. And, with summer right around the corner, the playground is gearing up for its big opening day on June 20.

O'Conner Pool is one of the best public pools in the city. It's near the Schuylkill River Park and all the fun on South Street West. It returns again this year as part of the Swim Philly program, reimagining it as a "vibrant public space," and the free kids summer swim team has already started this month. Get more information on their website.

This playground at 10th and Lombard is always bumpin' with families. The sprayground, which turned on in late May, is just an added bonus to the park, which also features a dog park, basketball courts, and tennis courts.

When you're not lounging in a hammock or hanging out in the beer garden at Spruce Street Harbor, find one of the many fountains in this seasonal pop-up park and cool off.

With multiple areas to get your spray on, families from all over come to Herron Park to cool off here. The sprayground is open now, according to Facebook, and you can check out the hours here. As one commenter suggests: bring some chairs and water toys.

This South Philly pool sits on the 3.7-acre Solomon Sacks Playground, so there are basketball courts and baseball fields to play around when you need to dry off. Jefferson Square Park is also across the street.

This one is also pretty new as it debuted a few years ago. It's small, but gets the job done. It gets steamy down by the Delaware in Queen Village. Plus, it just opened up for the summer with hours starting at 11 a.m. until 7 p.m.

Located near 3rd and Fairmount, it's a close-knit pool nestled within a densely populated neighborhood. Be mindful of the pool rules, listed here.

The sprayground at Shissler Rec Center opened in 2013 with some help from the Mural Arts Program and the city. Kids love this place, which goes by the theme "Take me to the River."

The John B. Kelly Pool in Centennial Park offers a big pool with swimming lanes, plus a great backdrop of the Please Touch Museum. There's a great lawn to camp out on, as well.

We defy you to not have any fun running through a water shooting rainbow. It's impossible.

Bonus: Mt. Airy Playground at 7001 Germantown Avenue also has a big spray fountain.

Venice Island in Manayunk is a park, recreation, and performance center that is managed primarily by the Philadelphia Parks and Recreation Department. Designed by local landscape architecture firm Andropogon Associates, the park includes state-of-the-art water features that demonstrate water retention in an urban environment, as well as recreational facilities for basketball and outdoor performances, space for a dock, outdoor sculptures, and a theater. It’s certainly one of the coolest (get it?) places on this list.
