Down at the Berkeley Marina you'll find one of the Bay Area's all-time classic kids' attractions: the Adventure Playground. This unique place at the foot of University Avenue is no ordinary playground, however. At first glance, it actually looks more like a junkyard than a playground, but it's actually an amazing outdoor wonderland where kids can let their imaginations and creative energy run wild and build with hammers, saws, nails, paint, and recycled materials. Don't worry—it's not a Lord of the Flies-style free for all.
