North of Walden, the North Platte River follows a 150 mile winding route through canyons and valleys. While most of the river is in Wyoming, there is a beautiful and productive section north of Walden to the Wyoming border. You can expect to find large brown trout and rainbow trout. The section from the southern boundary of the Routt National Forest north to the Wyoming border is designated a Wild Trout Water and is not stocked. In this zone, only artificial flies and lures are permitted. Also, the daily bag and/or possession limit is 2 per day. With the exception of the Northgate Canyon and the stretch below Six Mile Gap, the majority of the Upper North Platte River tends to offer easier floats and good fishing during moderate flows.
Since the river is in both states, keep in mind that fishing licenses are required from both states.
The signed access point is off SR125 about 5 miles below the Wyoming border.
Overall, North Platte River is the 28th most popular fly fishing river of all 47 fly fishing spots in Colorado.
