If you want a good amount of decent salmon, get thee to Seward in July for a couple of silver salmon charters. 6 fish per person per day will add up for you if you want to take a couple of boxes of good quality salmon home. I'd rather have those than sockeye from a river, but that's just me. If you really want to ring the bell, show up for your charters with a small insulated fish bag full of ice, and ice down your fish immediately after bleeding. Not all charters put your fish on ice after bleeding, and the quality difference is apparent. Pray dear Lord also that you hang a king or two...Seward feeder kings are incredible eating. Then, drive around and fish for various trouts, chars and grayling. I think you'd have more fun that way, with fewer people and better scenery. Grayling along the Denali Highway is a riot, with incredible scenery, if a bit buggy. Salmon get all the attention, and you're driving by world-class stream fishing only to stand shoulder-to-shoulder to fish salmon.

If you want kings, PM Calvin on this site, and plan a separate trip to SE AK.
