In 1999, my family and I moved to Colorado, settling in the Springs area. Coming from the East Coast, where I was used to bass fishing with spinning rods and catching stocker trout in lakes, this was a whole new world. My first taste of fly fishing happened on the Dream Stream section of the South Platte River. I began with nymphing, but I quickly grew frustrated with it. On a whim, I decided to try dry fly fishing, and after a few trips, I finally hooked my first 20+ inch rainbow on a caddis fly. Colorado is truly a special place for trout fishing. The abundance of rivers and streams, paired with the stunning natural beauty, make it an angler’s paradise. There’s something surreal about fishing the high plains while watching bison roam in the distance—all while casting to big fish. This place continues to fuel my passion for fishing every year.
In this article, we want to help fellow anglers discover some of Colorado’s best trout fishing spots. Over the years, we’ve explored many of these rivers and streams ourselves, learning what works and where to find the big ones. But we didn’t stop there. To make sure we’re covering the hidden gems, we polled our followers, reached out to local fly shops, and consulted with expert guides who know these waters inside and out. By combining our own experiences with their expert insights, we’ve put together a list of some of the top fishing spots in Colorado. Whether you’re a seasoned pro or just getting started, we hope this guide helps you find your next great adventure on the water.

#28 – Boulder Creek
Boulder Creek is one of the most accessible and enjoyable fishing spots right in the heart of town. This stretch flows through Boulder and offers easy access with plenty of opportunities to catch small, eager brown trout. From Arapahoe to Eben G. Fine Park, anglers can expect to find fish willing to take dries, nymphs, and streamers in nearly every riffle and run. While the creek sees heavy pressure, the fish remain relatively easy to catch, especially if you focus on watching your backcast—overhead casts tend to snag trees.
The walking path along the creek makes it easy to explore the water, which is filled with pockets, holes, and riffles. Dry droppers work best most of the year, but nymphing is productive in early winter and spring. During the summer, college kids tubing down the creek can make fishing a bit tricky, but early mornings and late fall offer the best opportunities.

The creek is typical of Southpark’s small waters, requiring short, careful casts with dry flies, nymphs, or streamers. Access is limited, so be considerate of other anglers.
