First time Zipliner here... Went with my adult son and we had a very enjoyable time. The highlight of the tour, besides spending some quality time with my son, was that one of the platforms offers an incredible view of McKinley. I was a little worried before heading out that this was going to be difficult or scary or something crazy (like bungie jumping)? However, it was not scary at all and was very controlled and safe. There are a total of 9 ziplines on the trail and three bridges. You essentially feel by the end that you are ziplining on your living room couch and simply taking in the view (which is nice). The only downside is that with a large group, it takes about 2-1/2 hours to do a zipline course that would otherwise probably only take 30 minutes. The guides are very detailed at locking everyone in so there are no problems (which is great!), but it simply makes things kind of slow. So, there is ample time to talk to the other people in your group. We were with 8 people, including three female doctors from Austrailia and it was interesting talking to a diverse group. We also learned a new saying that they used since one of them was a little scarred. It was "Think of England!". I won't go into the meaning of this saying, but it was funny! Anyway, we had a great time, just be patient and enjoy the moment!
