ColoradoFlyBox is family-owned with over 30 years of experience fishing Colorado rivers and high mountain lakes. We stand behind the quality of the flies we sell and will do our best to make you a lifelong customer.

Our two-part mission is to provide you with proven selections of nymphs and dry flies tailored to the time of year and waters you like to fish in Colorado and to help make fly fishing accessible to more anglers by providing these selections at a great value.

Each pattern and size included in our fly assortments were selected based on collaborations with local experts and professional guides. While nothing beats the advice of an experienced guide, our assortments will give you effective imitations of the bugs the fish will be feeding on at the time of year for the river of your choosing. With a little time observing the river and a bit of trial and error, you’ll find what fish are biting on and have a successful day on the water. In addition to our curated assortments, we also provide you the opportunity to create your own custom assortments. If you’re like most of us, you never feel like you have all the flies you need. Let us know if we’re missing your favorite pattern or size — we’re always looking to expand our inventory!

Thank you for visiting our website and buying our flies.

May the fish quake with fear at the mere mention of your name. Tight lines and happy fishing!
