2500 W. Lunt

This is hands-down the best hide-and-seek spot in Chicago. I still remember a sixth-grade school scavenger hunt that included finding a duck feather. For that, we headed straight to Indian Boundary. One of the few Chicago parks with a small zoo (llamas and goats) and duck pond with a small island, Indian Boundary's pretty setting includes new expanses of natural-habitat gardens, a big old sprinkler/wading pool area and, of course, the rambling wooden maze of a playground. This is one of those old-fashioned '70s-era structures that begs to be climbed, conquered and hidden in. Foot bridges sway and creak, fat tire structures invite crawl-throughs. The park's fieldhouse has public bathrooms, and there are three tennis courts. If you walk the zoo path, the best time to view the animals is 9 a.m.-4 p.m.
