I've been to several zipline attractions and this is by far the best one that I have been to. The guides are wonderful and the Ziplines are long and fast. Another plus to Ocoee Zipz is the fact that the guides will teach you how to do tricks on the ziplines, and will encourage you to try these out for yourself when it is appropriate and safe. That was a blast!
You definitely need to give this place a try; you will not regret it. Also, if you are into whitewater rafting you can make a day of it and zipline and raft as they do both.
