Cheesman Canyon

Overview

Cheesman Canyon is widely regarded as one of the most challenging and rewarding tailwater fisheries in the western United States. Located below Cheesman Dam on the South Platte River, the canyon cuts through dramatic Pikes Peak granite, creating a rugged, beautiful setting that contrasts sharply with the open meadows upstream. The river here runs crystal clear through deep pools, boulder-strewn pocket water, and long riffles that hold exceptional numbers of wild brown and rainbow trout.

What sets Cheesman Canyon apart is the quality of its fish and the difficulty of catching them. Decades of catch-and-release management have produced a population of large, wild brown trout that are extraordinarily selective and wary. Fish regularly exceed 16 to 20 inches, with some genuine monsters in the deeper pools. These trout have seen every fly pattern imaginable and demand flawless presentations, fine tippets, and precise matching of the hatch.

The canyon itself adds to the challenge. Access requires a steep hike down the Gill Trail, and once on the water, anglers navigate large boulders and slippery rock. The effort filters out casual anglers and rewards those willing to put in the work. On any given day, Cheesman Canyon can humble even the most experienced fly fisher or deliver the fish of a lifetime.

Access & Parking

Cheesman Canyon is accessed from the Gill Trail, located off Forest Road 211 (Cheesman Canyon Road) near Deckers, Colorado. From Denver, the drive takes approximately 1 hour and 15 minutes via US-285 to Pine Junction, then south on County Road 126 through Deckers.

• Upper Parking (Gill Trail): The primary access point. The Gill Trail descends approximately 500 vertical feet over about one mile to the canyon floor. The hike down takes 20-30 minutes; the climb back out takes 30-45 minutes and is strenuous. Bring trekking poles and good footwear.
• Wigwam Club Boundary: The upstream boundary of public water is marked by signs at the Wigwam Club private property line. Do not wade or fish above this boundary. The public catch-and-release section extends downstream for approximately 1.5 miles.
• Lower Canyon: The lower end of the canyon can be accessed from downstream near Deckers, but this involves significant boulder scrambling and is less commonly used.

Regulations

Cheesman Canyon operates under the most restrictive regulations on the South Platte, specifically designed to protect this world-class wild trout fishery:

• Tackle: Flies and lures only. No bait fishing is permitted.
• Bag limit: Catch and release only. All fish must be returned to the water immediately.
• Season: Open year-round when road access permits. The access road (FR 211) is often closed in winter.
• License: A valid Colorado fishing license is required.

Barbless hooks are not legally required but are strongly encouraged. Use rubber-mesh nets, keep fish in the water while unhooking, and wet your hands before handling any fish. These trout are too valuable to risk injuring.

Tips from Locals

• Go small or go home. Cheesman fish see heavy pressure year-round. Downsize everything — use 6X or 7X fluorocarbon tippet and flies in #22-26. If fish refuse your offering, go one size smaller and one shade more natural.
• Master the reach cast. Drag-free drifts are everything in the canyon. The complex currents between boulders create micro-drag that educated fish instantly detect. Use reach casts, slack-line casts, and stack mends to extend your drift.
• Polarized glasses are essential. Sight fishing is the primary technique. You need to see the fish before you cast. Amber or copper lens tints work best in the canyon's variable light. Study the water column — trout often hold 12 to 18 inches off the bottom.
• Work upstream. Wade slowly and fish upstream through the canyon. Trout face into the current, so approaching from below keeps you out of their line of sight. Move no more than 20 feet between casts.
• Bring water and food. The hike out is steep and tiring. There are no facilities in the canyon. Bring plenty of water, snacks, and layers. Cell service is unreliable.
• Time your visit. Midweek fishing is dramatically better than weekends. If you must fish weekends, arrive at the trailhead by 6 AM. The best fishing is often in the afternoon when BWOs start hatching.
