We spent a week on Maui and had a day without anything planned. We decided to try zip lining and found a flyer for North Shore Zipline. The Day ended up being one of the highlights of the week for my kids. There is a guy there, Kevin I believe, that looks like he smoked his breakfast. As soon as he opened his mouth I could tell we were in for a fun day. I am not saying that the other guides would not be worth the trip, but it has been a long time since my wife, kids, and I have laughed so hard. If you can choose your guide, I would suggest requesting him. He is very intelligent, witty, and full of one liners. He talks like he is highly educated and I am sure he is a zip line guide by choice.(not saying that he does not have an important position). In addition to Kevin's awesome guide experience the views are awesome. Northshore Zipline company makes safety their first priority and I would recommend the trip. Very reasonably priced.
