Looking for the best trout fishing in the United States? Whether you’re chasing wild cutthroat in alpine lakes or casting for trophy browns on a scenic river float, the U.S. is home to some of the world’s most iconic trout fisheries. From the towering peaks of Colorado to the wild rivers of Montana, anglers have endless opportunities to find their perfect cast.
At Kirks Flyshop, we’ve been guiding anglers through some of the most productive trout waters in Estes Park and Rocky Mountain National Park since 2002. We know what makes a destination stand out—and we’re sharing our top picks to help you plan your next adventure.
What Makes a Trout Fishing Destination the Best?
Not all trout streams are created equal. The best places to fish for trout in the U.S. typically offer:
-
Diverse Trout Species – Rainbow, brown, brook, and cutthroat trout thrive in healthy systems.
-
High-Quality Water – Clean, cold water with rich aquatic insect life creates ideal trout habitat.
-
Scenic Surroundings – Great fishing is even better when you’re surrounded by mountain peaks or wild canyons.
-
Accessibility and Variety – Whether you want a float trip, a short walk-in spot, or a full-day backcountry hike, variety matters.
-
Experienced Local Guides – A knowledgeable guide can turn a good day into a great one, especially if you’re fishing somewhere new.
Top US Regions for Trout Fishing
1. Colorado – The Crown Jewel of Western Trout Fishing
Colorado earns its place at the top thanks to high-elevation lakes, scenic rivers, and healthy trout populations. At Kirks Flyshop, we specialize in fishing the waters around Estes Park, the Big Thompson River, and Rocky Mountain National Park. These waters offer year-round action, crystal-clear streams, and a true Colorado wilderness experience.
And for those seeking a float trip, the Upper Colorado River near Kremmling delivers stunning views, thousands of trout per river mile, and the chance to land a trophy. Ask about our overnight float trips for a full-on immersive experience.
2. Montana – Big Sky Country for Big Trout
Montana is one of the most well-known trout fishing destinations in the U.S. Rivers like the Yellowstone, Bitterroot, Madison, and Missouri draw anglers from around the world thanks to strong wild trout populations and reliable hatches. These rivers are accessible to wade anglers and float fishers alike.
Montana is especially popular for dry fly fishing during summer, when caddisflies, mayflies, and terrestrials are abundant. With public access points and fishing-friendly regulations, it’s easy to plan a DIY trip—or hire a local guide for a more productive experience. Whether you’re targeting cutthroat or chasing larger browns, Montana offers variety, consistency, and quality water.
3. Idaho – Hidden Gems and Trophy Fish
Idaho has some of the best trout fishing in the West, but it’s often less crowded than neighboring states. The Henry’s Fork, Silver Creek, and Salmon River are all excellent options for fly anglers.
Silver Creek is known for its crystal-clear spring water and selective trout, while Henry’s Fork is home to strong rainbow populations and technical dry fly conditions. If you prefer larger water with room to explore, the Salmon River is a good fit. Idaho is a great pick for anglers looking for solitude, public access, and the chance to catch wild fish in clean water.
4. The Smoky Mountains – Wild Trout in the East
The Great Smoky Mountains National Park offers hundreds of miles of trout streams. It’s one of the best options for fly fishing east of the Mississippi. Anglers can find wild brook, rainbow, and brown trout throughout the park.
Streams here are small and fast-moving, making them well-suited for short casts and dry flies. Most creeks are accessible by car or foot, and no trout stocking is done inside the park—so every catch is wild. If you’re based on the East Coast or looking for a lower-elevation trip, the Smokies provide easy access to year-round trout fishing.
