Slide Mountain at Pier 6

A sprawling sandbox with little wooden huts to hide in, best for younger kids. Bring a bucket.

Spray jets to dodge and water to push around and experiment with. Bring a towel.

Pick a painted horse on a century-old carousel and ride it with the skyline right outside.

Giant loose foam blocks your kid can build with, plus sand to move and water when it's warm. Endlessly rearrangeable.

Granite slides at different heights, tree houses to scramble through and sand and water to mess with. Every age finds a slide.
