Juneau and S.E Alaska cannot be discounted during the summer. The scenery is amazing, hiking up Mt. Juneau or on the glaciers is a once in a lifetime experience, and I have never been out in Juneau without seeing whales up close and having Eagles come visit us. Kings are the ultimate prize and occasionally you can catch a "white King" which has buttery white meat vice the "salmon" colored meat - absolutely amazing. Kings can be caught year round but aim for late May - July. Silvers are also good eating and are the most fun to hood into, they really fight. They start running in July and peak in late August and early September. Reds, Humpies, and Coho are also available but not necissarily target by sport fishers. Dont get rid of the Coho if you catch them though, they are amazing smoked.
Jerrys Meats in Juneau is by far the best to take care of your catch. Make sure you have them smoke some meat for you, it is the best in Alaska.
