My husband and I (age 65-66) did the Captain Zipline tour on August 20, 2014. We were nervous because of our ages and the fact that we hadn't done a zipline before. We are in fairly good shape for our ages. Upon arrival we were welcomed by Josh. The check in process was very easy and we waited for all participants to arrive. There were 14 in all, two children, several middle aged adults, and several senior citizens. They have GoPro cameras for rent if you want one for $29. They give you the card from it at the end of the tour. After we all received the gear to wear, we were given an individual lesson on a short zipline that is close to the ground. Then we proceeded by van to six different ziplines which increased in length and degree of descent. You have to do short hikes between the ziplines. Some are fairly steep, but short. Josh and James were wonderful guides and were funny, helpful, kind, and informative about the surroundings, i.e. rocks, mines, etc. We never feared for our safety. This was such a great experience and we both can't wait to do it again!
