WHEN TO FLY FISH IN COLORADO
Colorado is one of the most iconic fly fishing destinations in the United States. With its high alpine lakes, pristine freestone rivers, and spring-fed creeks, the state offers a wide range of opportunities for anglers of all skill levels. Whether you’re casting dry flies for rising trout or drifting nymphs through a quiet run, timing is key to having a successful fly fishing experience.
At Sage Outdoor Adventures, we provide guided fly fishing trips on exclusive private waters near Vail and Beaver Creek, where the scenery is unmatched and the trout are wild and healthy. In this guide, we’ll walk you through when to fly fish in Colorado and how our guided experiences can help you make the most of every season.
Colorado’s Fly Fishing Seasons at a Glance
When to fly fish in Colorado depends on what kind of fishing experience you’re looking for. Each season brings its unique challenges and opportunities. From spring runoff to fall spawning, understanding seasonal trout behavior and water conditions can make all the difference in your fishing experience. Here’s what to expect throughout the year:
Spring Fly Fishing in Colorado (March to May)
Spring marks the beginning of the fly fishing season for many anglers. As winter recedes, rivers and creeks begin to thaw, and trout become more active after the long, cold months. March and April can offer exciting fishing with blue-winged olive hatches and hungry fish looking to bulk up.
This time of year also brings changing water levels as snow begins to melt at higher elevations. While this can make conditions unpredictable, it also presents an excellent opportunity for guided fishing. At Sage Outdoor Adventures, our local guides monitor river conditions daily and have access to spring-fed private ponds that remain fishable even during runoff. This gives our guests an advantage when public waters are muddy or blown out.
Summer Fly Fishing in Colorado (June to August)
Summer is the peak season for fly fishing in Colorado. By mid to late June, most rivers are clearing up from runoff, and the bug life is in full swing. Dry fly fishing is at its best during this time, with prolific hatches including caddisflies, stoneflies, and mayflies.
July and August offer consistent conditions, warm weather, and longer days, making them ideal for both beginner and experienced anglers. The trout are aggressive, and the fishing can be fast-paced, especially in the early morning and evening hours.
Sage Outdoor Adventures offers full and half-day guided fly fishing trips during the summer months, providing access to over 6,000 acres of private land and carefully managed ponds. Our guides focus on creating a stress-free experience by handling everything from gear and instruction to fly selection and safety. If you’re traveling with family, summer is the perfect time to introduce kids or first-timers to fly fishing in a controlled, scenic, and productive setting.
Fall Fly Fishing in Colorado (September to November)
Fall is a favorite season for many seasoned fly anglers. As the air cools and the crowds thin, trout begin their pre-winter feeding frenzy. Brown trout enter their spawning season, becoming more aggressive and territorial, which makes for exciting streamer fishing.
September is still warm enough to see sporadic hatches, while October and November bring lower, clearer water and solitude on the rivers. It’s the perfect time for those who want to experience Colorado’s natural beauty without the busyness of peak tourism season.
At Sage, fall fly fishing is all about immersion. You’ll find yourself surrounded by golden aspens and mountain views while working a slow presentation through quiet water. Our private access ensures that you’re not competing with other anglers, and our guides tailor each outing to the conditions and your preferences.
Winter Fly Fishing in Colorado (December to February)
While winter is the quietest time of year for fly fishing in Colorado, it still offers opportunities for those willing to bundle up and slow down their presentation. Tailwaters, which are rivers below dams, often remain ice-free and provide consistent flows and temperatures that keep trout active year-round.
Sage Outdoor Adventures offers private access to spring-fed water that remains open throughout the winter months, providing a peaceful and slow-paced fishing experience. Our guides are skilled at teaching winter tactics, such as fishing midges and small nymphs with long leaders and light tippet.
Winter trips are more intimate, and conditions require patience and skill. Still, for those looking to avoid crowds and test their technical ability, it’s a rewarding challenge.
When to Fly Fish in Colorado with Sage Outdoor Adventures
While fly fishing is possible year-round, the best months for a well-rounded experience are May through October. During this time, water temperatures are ideal, insect activity is high, and trout are at their most aggressive.

What sets Sage Outdoor Adventures apart is our access to private water that remains productive throughout the season. You won’t have to worry about high-pressure fishing spots or public access limitations.
