Misty Fjords by float plane is AWESOME and I can highly recommend SeaWind Aviation. Tom and I had the opportunity to take that trip while in Ketchikan and it was a highlight of the cruise. Here is a link to Tom's special report:

While in Ketchikan, make sure to sample some of the best halibut and chips to be found in Alaska at Burger Queen. You can read more about this little local treasure at the Port Reviews site as well.
