Harriman State Park

Below the Box Canyon the water slows and flattens into a beautiful meadow that offers a true “spring creek” experience over the next 10 miles. There is good access along the water at Last Chance to the upper parking lot of the Harriman State Park. The renowned Harriman State Park, often referred as the “Railroad Ranch” is arguably the finest stretch of fly fishing water in the world. 

The river here is famous for its abundant and often large rainbow trout, which can be particularly selective, demanding precise casts and delicate presentations of dry flies and nymphs. Wading is generally good, allowing anglers to carefully stalk rising fish. Blindly fishing nymphs, a common practice on most trout streams of the west, is usually a complete waste of time and effort on this water. 

Access to this water is limited to walk-in only. Parking access is available at Last Chance, the famous mailbox on Highway 20, Osborne Bridge, Harriman Park headquarters, and Forest Service Road #313, commonly referred to as Wood Road #16. 

If you’re into numbers, the “Ranch” is not your kind of place. The trout are extremely selective, requiring a perfect “drag-free” drift, light tippets and tiny flies. Trout are not concentrated and finding fish feeding can be difficult. If you’re lucky enough to hook one, plan on the battle of your life. Even the most experienced anglers consider landing a couple of big rainbows a great day. The Harriman Park experience is more than about fishing. The stunning scenery of the park, with the Teton Mountains as a backdrop, enhances the overall experience, making it a truly special destination for dry fly purists.
