The Arkansas River running through Fremont County is among the most productive fly fishing rivers in the Rocky Mountain West. The river runs for miles through varying terrain — from the wide meadow stretches above Florence to the tight canyon water of the Royal Gorge section — offering dramatically different fishing experiences within a short drive of downtown.
Gold Medal Waters
Colorado designates certain river sections as "Gold Medal" — a recognition that the waters support exceptional populations of large, wild trout. The Arkansas River holds Gold Medal designation for nearly 100 miles through Fremont and Chaffee Counties.
The peak season runs from late spring through fall, with hatches occurring throughout the warmer months. The caddisfly hatches in June and July are legendary — fish rising everywhere you look.
The Bighorn Sheep Canyon Section
From Salida east to Cañon City, the river runs through Bighorn Sheep Canyon — a dramatic section with Class II-III rapids that also holds exceptional brown and rainbow trout. This section is accessible from US-50 with multiple pull-outs and walk-in access points.
The water here tends to be slightly more technical than the meadow stretches upstream. Nymphing rigs dominate, but dry fly fishing is excellent during hatches.
Near Florence
Just west of Florence, the river braids through a series of wide, gravel-bottomed runs that hold large brown trout. These slower, deeper pools are accessible by foot from several public access points.
Access and Regulations
The Arkansas River is regulated as a catch-and-release, flies-and-lures-only stretch through the Gold Medal sections. Check current Colorado Parks & Wildlife regulations before your trip — size limits and season dates can vary by section.
Several local outfitters in Cañon City and Salida offer guided float trips and walk-wade guides. A half-day with a local guide is worth the investment for first-time visitors — the productive water isn't always obvious, and guides know the hatches.
Best Access Points Near Florence
The river fishes well almost any time of year, but late September through early November is special — the crowds are gone, the aspens are turning, and the trout are feeding aggressively before winter.
