Hiring a Henry’s Fork Guide
Hiring a Henry’s Fork Guide has its benefits whether you’re a first time fly fisher, veteran angler, IFFF certified casting instructor, or a guide in Alaska. The main reason, the Henry’s Fork is one of the most diverse rivers in the world and spans 127 miles!
When most people picture fishing the Henry’s Fork they imagine fishing the Harriman Park (aka Railroad Ranch). It’s a wide, slow moving spring creek through breathtaking high mountain meadows being overlooked by the Bitterroot mountain range. This section is 8 miles and can have fish almost anywhere. They are smarter than most fish as well. You’ll have to practice the 3 P’s of fly fishing; Presentation, Presentation, Presentation.
The truth is that the Railroad Ranch is only one minor part of why the Henry’s Fork is so amazing. You have the Box Canyon, Hatchery Fork, Mesa Falls, Warm River, Ora, Vernon, Chester, Fun Farm, & more! All Three Rivers Ranch guides are experts in this amazing Blue Ribbon fishery and the mind blowing amount of insect life that feed the approximately 6200 fish per mile.
