How to Plan Your Trip to the Best Fly Fishing Spots in the US
Once you have picked a destination, build the trip backward from the hatch or run you want to fish, then check current flows and regulations through the relevant state fish and wildlife agency before you go. Tailwaters fish well in shoulder seasons when freestone rivers are blown out, so they make excellent backup plans. For your first trip to any unfamiliar water, book a local guide for at least one day; you will learn the river faster than a season of trial and error.
Match your tackle to the target. A 5 weight covers most western and eastern trout, you will want a 6 or 7 weight for big water and streamers, an 8 weight for Alaska rainbows and salmon, and a 9 weight or heavier for saltwater species like tarpon. Pack layers, polarized sunglasses, and more flies than you think you need, because the shops near these rivers know exactly what is working that week.
Final Thoughts on the Best Fly Fishing Spots in the US
You do not have to fish all 25 of these waters to call yourself a serious angler, but every one of them earns its place on a list of the best fly fishing spots in the US. Pick the destination that fits your season and skill level, do your homework on flows and regulations, and treat each river with the respect it deserves.
