Roaring Fork River

The Roaring Fork River is one of Colorado's most productive wild trout fisheries and one of the premier fly fishing destinations in the Rocky Mountains. Beginning high above Aspen and flowing through Basalt, Carbondale, and Glenwood Springs before joining the Colorado River, the Roaring Fork is famous for its crystal-clear water, incredible insect hatches, explosive dry fly fishing, and healthy populations of wild brown and rainbow trout.
Fed by cold mountain tributaries and protected by exceptional habitat, the Roaring Fork fishes beautifully throughout much of the year. From technical dry fly fishing during prolific summer hatches to trophy trout opportunities during the spring and fall, this river consistently delivers unforgettable days on the water.
At Colorado River Outfitters, we spend countless days guiding the Roaring Fork each season. Our experienced guides know every productive riffle, bucket, seam, and undercut bank, allowing us to consistently put clients in front of quality trout while showcasing one of Colorado's most beautiful river valleys.

The stretch of the Roaring Fork from Basalt to Carbondale is widely considered one of the finest dry fly fisheries in Colorado. Cold water flowing from the Fryingpan River combines with excellent insect populations and ideal trout habitat to create consistent fishing throughout the summer and into the fall. With spectacular views of Mount Sopris, cottonwood-lined banks, and crystal-clear riffles, every day on this section feels like fishing in a postcard.
Legendary Dry Fly Fishing
If your dream day involves watching trout confidently rise to dry flies, the Upper Roaring Fork belongs on your bucket list. Throughout the summer, trout feed aggressively on an incredible variety of aquatic insects, creating outstanding opportunities for anglers who enjoy visual fishing.
Major hatches include:
-
Caddis
-
Pale Morning Duns (PMDs)
-
Blue Winged Olives (BWOs)
-
Yellow Sallies
-
Golden Stoneflies
-
Green Drakes (during favorable years)
-
Tricos
-
Midges
These dependable hatches often provide all-day dry fly opportunities, especially during the cooler mornings and evenings of midsummer.
Healthy Wild Trout
This reach supports exceptional populations of naturally reproducing wild brown trout and rainbow trout.
Most fish range between 12 and 18 inches, but every week anglers land beautiful trout exceeding 20 inches. Strong current, abundant insect life, and cold water create incredibly healthy fish that fight well above their size. Whether you're fishing pocket water, long riffles, or classic runs, nearly every piece of water has the potential to hold feeding trout.
Technical Yet Rewarding
The Roaring Fork rewards anglers who enjoy making accurate casts and thoughtful presentations. Long leaders, natural drifts, and careful wading often make the difference between a good day and an unforgettable one. Fortunately, our guides help anglers of every experience level learn to fish this incredible river successfully.

As the Roaring Fork leaves Carbondale and flows toward Glenwood Springs, it grows significantly in size and character. Additional tributaries increase both flow and nutrient levels, creating one of the most productive trout fisheries anywhere in Colorado. This lower section offers incredible diversity. Long riffles, deep buckets, undercut banks, boulder gardens, and classic runs provide endless habitat for large wild trout. Many experienced anglers consider this the premier float fishery in western Colorado.
Trophy Wild Trout
The Lower Roaring Fork is known for producing exceptional wild brown trout, cutbow trout and rainbow trout. Rich insect populations and abundant food allow fish to grow quickly, with trout over 20 inches caught every season. Whether drifting nymphs through deep seams or throwing articulated streamers against cut banks, every cast carries the possibility of connecting with a truly memorable fish. This is a section where quality often matches quantity.
Outstanding Spring and Fall Fishing
While this river fishes exceptionally well throughout summer, CRO guides eagerly anticipate the shoulder seasons. Ask any of our guides and they will emphatically tell you "March is the best month to be on the Fork"
Spring
As water temperatures begin to warm before runoff, trout become increasingly active. Blue Winged Olive hatches, midges, stoneflies, and streamer fishing create outstanding opportunities for anglers chasing large fish before summer arrives. This is often considered the best fishing of the year anywhere is Colorado.
Fall
Autumn transforms the Roaring Fork into one of Colorado's most beautiful rivers. Golden cottonwoods line the banks, crowds begin to disappear, and cooling water temperatures encourage trout to feed aggressively. Streamer fishing becomes increasingly productive, while Blue Winged Olives and late-season caddis continue providing excellent dry fly opportunities.
Float Fishing Paradise
The Lower Roaring Fork is perfectly suited for drift boat fishing. Floating allows anglers to cover miles of productive water while accessing trout that rarely see anglers on foot. Our guided float trips combine incredible scenery with consistently productive fishing, making this one of our favorite rivers to guide throughout the season.
