From Dillingham the journey inland on the Nushagak River takes you to many small villages that the average tourist doesn't get to. I don't have that many pictures of the actual villages of Ekwok, New Stuyahok, and Koliganek that I have gone to so I'm making this a trip from Dillingham - the town you'd get to from Anchorage.
Besides all the species of Alaskan wild salmon, there is a good chance you'd catch dolly varden, or grayling. There are lots of lodges along the Nushagak River, and smaller operators that are more affordable than some of the luxury $1000 a day lodges. Some friends of mine have a small fishing charter and or hunting guiding businesses out of Koliganek. If you're interested write me and I'll get you in touch with them.
It isn't probably a very inexpensive place for people to stay. This won't be a budget travel tip! But they really take care of their guests. I've only been invited up there as a member of the Aruvak Dancers. They have a gift shop, a bar, a fancy cook. It's a lovely building, on a lovely lake. Budget travel to Snake Lake would be like us locals to... drive up there with our own boats.
Equipment: Their web page has a long list of things you should bring. My suggestion is TWO bottles of bug dope. There are tons and tons of bugs up that way.
