For some people I know, hiking the Kalalau Trail on Kauai makes them break into a sweat. Others I know won't even think about driving the famous road to Hana. For those people, I do not recommend ziplining. But, if you have a general respect for high places, like I do, and you like speed, like I do, then, you'll love ziplining. It's still a relatively new adventure in Hawaii. In fact, you won't even find ziplining adventures on all the islands.
