Very much of a rip off production. Watch their weight limit. I had called for reservations and paid for 4. One child was small but said his last visit to the doctor weighed him at 76 lbs. So i paid for him, too. When we got there, he was just under and they would not let him go. They also would not refund the money paid for him even though they had 3 more show up late which more than made up for his reservation. So I paid for 4 and we sent 3 people. The ziplines were slow and uninteresting. no challenge. The kid probably could have gone without getting stuck. And furthermore, the guides expect a big tip at the end. perhaps i should have made up for the overpayment by stiffing their tip.
I called to appeal to the owner several times and got no response, only to say that those were the rules. Legal ripoff. My advice is to zipline in Kauai instead (if you must zip).
