We just got back on 7/2/06 from the NCL Star. We did the zipline tour in Ketchichan and really enjoyed it. It was alittle expensive at $159 a piece but we enjoy adventure and had never done a zipline before. You will be 80 to 140ft up in the treetops and the longest zipline is over 700 feet long. I think there were 7 ziplines in all and about 3 suspension bridges that you cross. We were lucky and had the first sunny day in a month for Ketchikan. The guides were really nice and the view from the first platform towards the bay were great. If you are interested we, my 19 year old daughter and 17 year old son also really enjoyed the rock climbing and rapelling in Skagway and the whale watching in Juneau with Orca Enterprises.
