Ultimate Fly Fishing Vacation on Wyoming's Miracle Mile



Big trout, an extended season, and low pressure from anglers makes for unforgettable fishing.

Private Access on the North Platte with Crazy Rainbow Guides

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 docking adjacent to private land.  The Crazy Rainbow Advantage provides plenty of wade fishing, relaxing gourmet stream-side lunches, and access to private restroom facilities.

The North Platte River

Blue Ribbon Trout Fishing

Come experience one of the most productive and exciting wild trout fisheries in the Rocky Mountain Region. Casper has an international airport with regular flights from Denver, Salt Lake and Las Vegas.

Blue Ribbon Trout Fishery

The Miracle Mile, Fremont Canyon and the Grey Reef tailwaters of the North Platte River are easily accessible from Casper, WY.

Wild Rainbows, Cutthroats, and Browns averaging 17 to 22 inches will keep anglers smiling. However, trophy fish of 10+ pounds are the main draw to this section of the North Platte. The combination of size and numbers of these fish make it one of the top destinations in the continental United States.
