Preparing for a Successful Fall Fly Fishing Trip in Colorado

Fall in Colorado is a magical time for fly fishing. Crisp air, vibrant foliage, and hungry trout make it one of the best seasons to hit the water. But the key to a successful trip is preparation. From understanding the hatches to packing the right gear, here’s how to make your fall fly fishing adventure a triumph.

Know Your Rivers and Hatches

Fall brings some of the most exciting hatches of the year. Knowing what’s happening on the water can mean the difference between a banner day and a bust.

• Blue-Winged Olives (BWOs): These small mayflies hatch from mid-September through November, particularly on overcast days.
• October Caddis: Big, bold, and active in late September through mid-October, these flies are a favorite among trout.
• Midges: A year-round staple, midges are especially important in cooler months when other hatches fade.

Top Spots: The Fryingpan River, South Platte River, and Gunnison River are prime destinations for fall fly fishing. Be sure to check local fishing reports for updates on conditions and hatches.

Gear Up for Fall Conditions

Fall in Colorado can be unpredictable, with chilly mornings, warm afternoons, and sudden changes in weather. Proper gear is essential to staying comfortable and focused.

• Clothing Layers: Start with moisture-wicking base layers, add an insulating mid-layer like fleece, and finish with a waterproof outer shell.
• Waders and Boots: Insulated waders and waterproof boots will keep you warm and dry. Consider neoprene options for extra insulation.
• Accessories: Don’t forget a fleece-lined beanie, fingerless gloves, and wool socks.

Pro Tip: Pack a lightweight rain jacket—even on sunny days, Colorado weather can change in an instant.

Choose the Right Flies

Matching the hatch is critical for fall fishing success. Carry a well-stocked fly box with these essentials:

• Parachute Adams and BWO emergers for Blue-Winged Olives.
• Orange Stimulators and Elk Hair Caddis for October Caddis.
• Zebra Midges and Griffith's Gnats for midge action.

Pro Tip: Have a few streamers like Woolly Buggers or Sculpins in your arsenal. Fall is a great time to target larger, aggressive trout.

Time Your Fishing for Peak Activity

In fall, trout are most active during the warmest parts of the day. Aim to fish between late morning and early afternoon when insect activity peaks, and trout are feeding actively.

Pro Tip: Cooler nights can slow morning hatches, so plan your start time accordingly.

Pack Smart: Essentials for a Successful Trip

A well-packed bag can save your day. Here’s what you shouldn’t leave home without:

• Fly Box: Include a variety of patterns to cover all likely hatches.
• Tools and Tackle: Tippet, leaders, nippers, and forceps are must-haves.
• Snacks and Drinks: High-energy snacks like trail mix and a thermos of coffee or tea will keep you fueled and warm.
• Sunglasses and Sunscreen: Fall sun can be surprisingly intense.
• Net and Wading Staff: Safety and convenience go hand in hand.

Understand Fall Trout Behavior

During fall, trout are in pre-winter feeding mode, aggressively bulking up for the colder months. They’re more likely to strike at larger flies, especially during streamer season. Target slower pools and deeper runs where trout are likely to conserve energy while feeding.

Pro Tip: Be stealthy in your approach. Fall’s lower water levels make trout more cautious.

Respect the Environment

Fall fishing is not just about the catch—it’s about appreciating Colorado’s incredible natural beauty. Follow these principles to preserve the experience for others:

• Practice catch-and-release with proper handling techniques.
• Leave no trace—pack out all trash, including tippet and leader scraps.
• Respect local regulations and seasonal closures.
