Fly Fishing on the North Platte River

Fly fishing for trout on Wyoming’s North Platte is more about the classic fly fishing experience than trophy trout – although there are plenty of trophy trout. Therefore, Fly fishing in Wyoming is the way it should be. It’s not unusual to spend the day landing big trout out of the river while seeing only a few other fishermen.

Orvis Endorsed Crazy Rainbow Fly Fishing Outfitters


Proud to have been branded the Orvis Endorsed Outfitter on the North Platte River, our fly fishing guides at Crazy Rainbow are the ideal combination of expert reputation and camaraderie. Our fly fishing guides love what they do, and they are passionate about getting you onto the good fishing. Crazy Rainbow also, offers great lodging opportunities that can be booked along with your fly fishing trip.

Because of Crazy Rainbow’s private land holdings along the Grey Reef tailwater, you will be one of the first boats on the river and can enjoy all the wade fly fishing and solitude you need for the ultimate fly fishing vacation. Big trout, an extended season, and low pressure from anglers makes for unforgettable fishing experience.

The private river access and eight private boat ramps at Crazy Rainbow are a distinct advantage unavailable with many other fly fishing outfitters. Wyoming’s property laws don’t allow public wade fishing or boat launching adjacent to private land. The Crazy Rainbow Advantage provides plenty of wade fly fishing, relaxing gourmet stream-side lunches, and access to private restroom facilities.

Blue Ribbon Trout Fishery

The North Platte River

The North Platte River has its beginnings in the high mountains of Colorado, entering Wyoming as a freestone river of excellent trout habitat. As the river continues across Wyoming, a series of dams creates tailwaters and a variety of trout fishing scenarios.

Blue Ribbon Trout Fishery


Long recognized as a Blue Ribbon trout fishery, the people of Wyoming, along with both state and federal agencies, have worked together to ensure this resource is protected. The North Platte River from the Wyoming line to Casper is managed first and foremost as a trout fishery. Development and livestock grazing are limited, and water flow is closely monitored in order to produce superior trout habitat.

Private River Access

Much of the North Platte River runs through the checkerboard land ownership pattern common in western states. The streambank and underlying river bottom along private land is not accessible to the public. Because of this land ownership pattern, private access is a large part of what makes fishing the North Platte with Crazy Rainbow so unique. We own large parcels of land adjacent to the river where our clients can walk/wade and enter and exit the river where ever they please.

Fishing Wyoming Waters

Three notable stretches of the river are viewed as prime fly fishing spots: the Grey Reef tailwaters, Fremont Canyon, and Miracle Mile. Crazy Rainbow now guides the Big Horn River at the end of the Wind River Canyon the Wind River widens out in an area called the Wedding of the Waters where it becomes the Big Horn River and enters the Big Horn Basin nationally known for it’s Blue Ribbon Fishing.


The local lakes provide you an added opportunity to try Carp Fly Fishing. Many people compare our Carp Fly Fishing to Red fishing on the flats. Reserve your Carp Fly Fishing with Crazy Rainbow Guides today.

My family and I have been customers of Crazy Rainbow for years. It would take us some time to try and calculate how many fish we have caught with them over the years.

BEYOND EXPECTATIONS! I spent a week in July fishing with Ugly Bug guides Justin, Troy, and Addie (also at the shop) on the North Platte catching rainbows, cutthroats, and browns. I have fly fished most of my adult years, and this was by far the best trip of my life.
