Flying through the rainforest canopy on a zipline is a fun, exhilarating, and safe way to truly get a "bird's eye view." In fact, you might even spot some birds and monkeys eyeing you curiously from the topmost branches of the trees! Contrary to popular belief, people usually don't find ziplining to be a stressful or frightening activity at all (unless you're very afraid of heights) -- the ride is actually quite smooth, and there's little else to do besides relax and enjoy the scenery.
