Come “swing like a gibbon” at Jungle Gym, a 35-foot-tall tree house, cargo-net climbing area, slide, and giant snake tunnel at the Nashville Zoo. It’s the largest community-built playground in America (perhaps there’s something to that Volunteer State nickname), and a perfect stopover between the African Savannah exhibit—teeming with giraffes, elephants, river hogs—and the Jungle Loop, where leopards, lemurs, and antelopes run wild.
