North Saint Vrain Creek is a picturesque Colorado waterway offering excellent fly fishing opportunities in a stunning mountain setting. Located in north central Colorado near Lyons, this freestone stream consists of three main branches that form the main creek. The North, Middle, and South forks each provide distinct fishing experiences with varied terrain and fish populations. Flowing from high elevations in Rocky Mountain National Park and the Indian Peaks Wilderness, the creek features pristine waters teeming with multiple trout species. The stream is characterized by pocket water, riffles, runs, and pools formed by large boulders that have tumbled down from canyon walls, creating ideal trout habitat throughout its course.
