You need a heart for adventure – but not necessarily a body of an athlete – to enjoy the thrill of zooming through the treetops and clambering across aerial suspension bridges at New England’s zip lines. In just a handful of years, these playgrounds in the tree canopy have sprung up across New England, serving people’s desire to unleash that inner Tarzan. Guides convey you safely along zip lines, through elevated obstacle courses, and across chattering rope and suspended bridges. Really fun for all averagely fit people as long as you carry enough weight to propel you (sorry, babies and toddlers). A great thing to do on a family getaway.
