I am not a parent, but I do take care of my sister's son at least 40 hours a week.
So, I am always on the look-out for fun spots to take him to in the City.
I also have a 70 pound, mostly deaf, rescue dog and she's a whole lot of puppy even though she's almost 4.
I check out any dog park or green square that looks tantalizing for her.
Often any place my dog likes, my nephew digs too....

"picturesque playground"
The playground rocks.
The swings have a magnificent view of the city and there's a sandbox and the structure is challenging and entertaining.
We have encountered several friendly kids and guardians and it's nice to play and then go relax on or walk around the grass.
It can get a little brisk here, so bring a coat. And make sure you sunscreen you and the little one as there's no real shade to speak of.
