West of Fort Collins and east of Walden, the Big Laramie River is popular with fly fishermen. The Big Laramie is a freestone river that is a tailwater fishery coming from Chambers Lake that runs down to the West Branch Laramie River confluence. The Laramie Rivers flow about 28 miles north to the North Platte River confluence.
The best section from fly fishing on the Big Laramie River is above Rawah Ranch where there is plenty of public access to go after brown trout and brook trout. Below Rawah Ranch, most of the access is private to Honholtz Lakes. Although, the first two miles from Rawah Ranch are known to be very productive.
Overall, Big Laramie River is the 35th most popular fly fishing river of all 47 fly fishing spots in Colorado.
