Before you go

fishing in Northern Colorado

Did you know everyone can fish in Colorado without a license on the first full weekend of June every year? But if it’s not the first weekend of June and you’re over the age of 16, you’ll need a license. Luckily, Colorado Parks & Wildlife makes getting yours easy. Both residents and non-residents can purchase annual and daily licenses online here. And they even host special fishing events throughout the year; you can see their event calendar here.

If you want to talk to the local experts, we recommend heading to Elkhorn Fly Shop in Loveland or St. Peter’s Fly Shop in Fort Collins. Elkhorn is a full-service fly shop, a manufacturer of their own fly rods and reels, and an educational facility where you can learn both how to make materials and how to use them.

With two locations in Fort Collins, St. Peter’s Fly Shop is a landmark of Fort Collins fishing culture. In addition to tools, expertise and the best fly selection in town, they offer frequent classes, events and free demos which take place both on the water and off.
