Perched on the eastern end of the trendy waterside development, Seventh Street Park was created with its littlest neighbors in mind. Small fountains and misting sprays shoot up from the stony street surface to offer a cooling distraction.

Not even a foot deep, the Canal Basin is safe for toddlers, fun for elementary-schoolers and refreshing for adults who just want to soak their feet. To get really wet, splash through the waterfall or run through the fountains, which feature a kaleidoscopic light show once the sun starts setting. Located on the banks of the Anacostia, it’s close to plenty of family-friendly eateries — including Rasa, Ice Cream Jubilee and Shake Shack — as well as a plaza full of fountains just a few blocks away at Canal Park. 355 Water St. SE.

This splash park is amazing. It’s also an actual maze. Nearly 300 mini geysers form a puzzle that’s equally captivating and refreshing.

Parents who don’t want to get in on the action can keep an eye on the frolicking from one of the shaded picnic tables nearby. 18056 Central Park Cir., Boyds, Md.
