Detailed Trail Description from our Guidebook
"Quite simply, this canyon, below Island Park Dam is quite simply a gorgeous place to cast a fly. Truly monster trout patrol this three-mile stretch, and their presence has enticed fly fishers for years. In this section, one has a reasonable opportunity to take a 10-pound trout on a dry fly, big nymph, or streamer, but it’s a challenge.

This trail guide covers the “where, when, and how: to fish in this region. You’ll get a full-page map and information on the known hatches, suggested equipment to bring, and the best flies to use."
