Adventure Playground (Berkeley, Calif.)
There's truth in advertising when it comes to Adventure Playground in Berkeley, Calif., -- this playground truly is an adventure. Kids visiting this playground should be prepared to build things: The play space is filled with plywood and board buildings (shanties, boats, forts, towers, bridges, you name it) that were constructed by kids with supervision, of course. Kids (and their parents) can check out real tools -- hammers, saws and nails or paint and brushes or bring their own -- and get to work as carpenters.
It's not all about tools and hammering, though. There's a suspended tire climbing structure, and did we mention the zip line? Smack in the middle of the playground is a zip line -- slide on down and a pile of sand is waiting to catch you.
