Cruises through Southeast with stops in Ketchikan mostly offer fly out fishing packages for salmon, and boat trips for halibut .
If you want to fish and not pay an arm and a leg ($600+), hop a cab in Ketchikan and head out to Ward Creek and Lake.
Having been all over Alaska from SE,Valdez, Kenai Cook Inlet, Dutch and Aleutian chain, upwards to St. Paul.
I have learned two things:
1. No such thing as bad weather, on bad clothing
2. There is really no good fishing in Alaska, only CATCHING
