Rainbow Trout
Ashton, Idaho, sits in the heart of some truly spectacular rainbow trout fishing. The Henrys Fork of the Snake River is the star attraction, offering diverse fishing opportunities from the legendary Harriman State Park (Railroad Ranch) to the Box Canyon's challenging waters. Spring and fall provide excellent fishing conditions, with hatches of mayflies, caddisflies, and midges drawing trout to the surface. Summer can also be productive, especially during the early morning and late evening hours. A crucial local tip: pay attention to the prevalent hatches and match your flies accordingly. The trout here are known for being selective, so accurate presentation is key. The Box Canyon section is particularly known for its large, wild rainbows, but it requires a drift boat or wading skills and a good understanding of the river. Remember to check the special regulations for different sections of the Henrys Fork, as they vary.
