Powell Barnett Playground (Seattle, Wash.)
Powell Barnett Park in Seattle, Wash., is divided into two sections, one for little kids (ages 2 to 5) and another area for the older set. The park features a variety of spinning and bouncing equipment as well as elaborate climbing structures -- including a giant red spider web made out of rope. For the older kids, there's a full-size basketball court. And for the little ones -- don't miss the tricycle maze and the wading pool (summer only).
Another cool feature? Believe it or not, it's the restrooms. Powell Barnett Park's restrooms are located in a castle-shaped building next to the play space, and are ADA accessible.
