For our 15th Anniversary, my wife and I decided to do the zipline/ropes bridge and rappelling course in Ketchikan. We had done ziplining 3 other times and always enjoyed it, but this was much higher and more fun! If you have never done it before, don't be scared, it is very safe, we had several people in our group of 10 that had never done it before and while nervous at first, they did great throughout the course.
The scenery was cool, eagles were flying around us at times just checking out these crazy humans trying to be like them! Daniel and Raymond were our leaders, and they did a great job; kudos to the entire staff at Kawanti for making a most enjoyable Anniversary excursion in Alaska!
Book it early so you don't miss out, it does fill up.
