The Rio Grande begins in the San Juan Mountains and offers one of the most classic river fishing experiences in Colorado. The stretch between Del Norte and South Fork is especially productive, combining accessibility with strong trout populations.

This is primarily a trout fishery, with rainbow and brown trout dominating. Mid-summer (June through July) is one of the best times to fish, as insect activity increases and trout become more aggressive.

The Rio Grande is ideal for anglers who want a traditional river fishing experience with consistent trout action and scenic surroundings.

The Fryingpan River is one of the most famous tailwater fisheries in Colorado and is known for producing large trout, including rainbow trout exceeding 10 pounds.

Located near Basalt between Aspen and Glenwood Springs, the river benefits from cold, controlled water released from Ruedi Reservoir. This creates stable conditions and allows trout to grow larger than in many freestone rivers.

This is a technical fishery—presentation matters. Fly fishing is dominant here, and anglers often focus on matching insect hatches.

The Fryingpan is best suited for anglers looking for trophy trout and a more precise, skill-based fishing experience.

The North Platte River offers a mix of accessibility and adventure. While some sections are easily reached, others require rafting or kayaking, adding an extra layer to the experience.

This river is known for producing high-quality trout, particularly in the meadow sections near Walden. The combination of structure, current, and habitat creates strong feeding zones.

The North Platte is ideal for anglers who want strong trout fishing with the option for a more adventurous, less crowded experience.

Gore Creek is a smaller but highly valuable fishery, especially for anglers interested in the state fish of Colorado—the Greenback Cutthroat Trout.

While it doesn’t have the size of larger rivers, it offers a more focused and intimate fishing experience. Clear water and smaller stream conditions require a careful approach and lighter presentation.

This is a destination for anglers who value species-specific fishing and a more technical, small-water environment.

The Upper Arkansas River, near Leadville, offers one of the highest-elevation fishing experiences in the United States.

This river combines alpine scenery with strong populations of brown and rainbow trout. The structure—boulders, bends, and varying current—creates ideal trout habitat.

Fishing here is heavily influenced by elevation and weather, making timing important. Summer and early fall are typically the most productive seasons.

This is ideal for anglers who want high-altitude fishing with strong trout populations and diverse water conditions.

Spinney Mountain Reservoir is known for its trophy trout and open-water fishing environment.

Located in Park County, this reservoir produces large trout, along with walleye and kokanee salmon. The lake’s structure and nutrient levels support consistent fish growth.

Boat fishing is common here, and anglers often target deeper water depending on season.

Spinney is best for anglers looking for larger fish and a reservoir-based approach rather than river fishing.

The Gunnison River is one of the most productive trout fisheries in Colorado, particularly in sections near the Black Canyon.

This river is known for large rainbow and brown trout, with some fish reaching sizes that are uncommon in most U.S. waters.

Access can be challenging, with steep terrain and winding roads, but the reward is a high-quality fishery with less pressure in certain areas.

The Gunnison is ideal for anglers who want big trout and are willing to work for access.

The Animas River flows through Durango and offers a mix of accessibility and strong trout fishing.

Despite its dramatic name, the river is surrounded by scenic landscapes and supports populations of brown, rainbow, cutthroat, and brook trout.

Fishing can be productive throughout much of the year, though larger trout can be more difficult to catch.

This is a solid option for anglers who want consistent trout fishing with easier access and nearby amenities.

North Delaney Lake is one of the highest mountain lakes in the country and is known for its high concentration of trout.

Located near Walden, the lake provides a stable habitat that prevents overfishing and supports sustainable populations. It is also used as a source for trout eggs to support other fisheries in the state.

This is a destination for anglers looking for high-percentage trout fishing in a quiet, high-elevation environment.

Cherry Creek Reservoir offers a completely different experience compared to most Colorado fishing locations.

Located near Denver, it provides easy access and a mix of species, including trout, walleye, and bass. It’s one of the few places where anglers can combine urban convenience with productive fishing.

This is ideal for anglers who want accessible fishing without traveling deep into the mountains.
