What's there: Cutthroat trout, rainbow trout, brown trout, whitefish.
Description: This is a classic, large, broad, sweeping river that is fished best from a boat. Driftboats and rafts are the preferred craft, but skilled paddlers can float it in a canoe or other boat. The river is famous for its dry fly fishing for cutthroat trout, so much so that Idaho Department of Fish and Game asks anglers to harvest rainbows to ensure a healthy and productive cutthroat population. The river also has huge brown trout that provide a bonus for trophy anglers. The most popular stretch of the river is from Palisades Dam down to the take outs near Ririe. The canyon section is a great opportunity for floating and camping.
Getting there: Take the freeways east to Idaho Falls and go east on U.S. 26.
Drive time: About 6 hours.
