The upper Teton River meanders through the farmland west of Tetonia in slow, looping bends, and is one of the better small-water fly-fishing streams in eastern Idaho. The river holds Yellowstone cutthroat trout — the native fish of the region — along with rainbows and the occasional brown. Fish are not enormous (most are 10 to 16 inches) but they take dry flies enthusiastically and the setting is hard to beat.
Access is from public bridges and a handful of marked fishing easements; much of the surrounding land is private ranch property, so wading from a legal access point and staying below the high-water line is the rule. The river is best from mid-June through October, with hatches of pale morning duns, caddis, and hoppers driving most of the action. Several outfitters in Driggs and Victor run float trips down the meander section.
