Idaho is an opportune place for beginner, recreation, and sport fishers alike. Broken up into seven regions, from Panhandle Region (home to Coeur D'Alene National Forest), to the Southeast Region (home to Caribou National Forest), there is an actively-stocked body of water in every corner. Popular in the state are mountain whitefish, walleye, catfish, trout, salmon, white sturgeon, and many more.
