The Story

The Ugly Bug Fly Shop is a full-service fly shop established in 1983. We offer our clients a one-stop shop for their outdoor needs in the central Rockies. Our experienced guides have great knowledge of the local waters. We can tailor your trip to any level of fly fisher.

Date Range

The Ugly Bug Fly Shop is open all year. We guide fly-fishing clients year round, weather permitting.

What is Provided to Customer

Our guided fly-fishing rates include the use of rods and reels; we also include leader, tippet, and flies. A lunch, waters, and sodas are also provided.

Region/Terrain Where You Fish

We are located in the heart of the Rocky Mountains in central Wyoming, at about 6,000 feet of elevation. We are based on the world-renowned North Platte River where we offer walk/wade and float trips on the Grey Reef, Miracle Mile, and Fremont Canyon stretches as well as Float Trips on the Big Horn River outside of Thermopolis Wyoming. These are very health fishery due to our low water temperatures and tailwater environment. Casper has an international airport with regular flights from Denver, Salt Lake City, and Las Vegas. Casper is also located conveniently right off I-25 for easy access by vehicle.

Typical Weather by Season

The average rainfall for this area is 12.5 inches per year, and temperatures vary with seasons but we are known for mild springs and falls with warmer bright, sunny summer days. We advise that all clients bring appropriate clothing and sunglasses; we can provide nearly everything else. Water temperatures range from 33-65 degrees depending on the season.

Frequently Asked Questions


Q. What months offer the best fishing in your area?
A. March through October are considered our best months. We do, however, offer guided fishing trips all year long. The winter fly fishing is some of the best in the lower 48; during the winter months there are very few people on the water. We also offer a discounted rate for these months if you are interested.

Q. What kind of weather should I be prepared for?
A. Casper's elevation is 5,200 feet above sea level. At this elevation the sun is intense and weather can change quickly. Be prepared for a range of temperatures and conditions. Layers work best so you can adjust to changing conditions.

  • Rain jacket and warm layers in spring and fall
  • Shorts/sandals or warm-weather gear in the summer
  • Light windbreaker in the summer
  • Polarized sunglasses
  • Hat
  • Sunscreen

Q. How do gratuities work?
A. Gratuities are not included or expected, but certainly appreciated. The average gratuity for our fishing guides is $50 per person, per day.

Species You Fish for by Season

Wild rainbows, cutthroats, and browns averaging 17 to 22 inches will keep anglers smiling. The combination of size and numbers of fish make it one of the top destinations in the continental United States. Not to mention, there is always the chance to catch a fish of a lifetime weighing in at more than 10 pounds.

We experience a wide range of hatches throughout the year. Midges (year -round), BWOs (April, May, June, September, October), PMDs (June, July, August, September), and yellow sallies (July, August). The North Platte is known for its nymph fishing, streamer fishing, and some dry-fly fishing.

What Should Customers Bring?

Lunch will be provided streamside on day-long guided trips.

For any other items you need, Casper has large chain stores such as Walmart, Walgreens, Target, and grocery stores.

Your camera, preferably in a water-resistant case. You'll want to be ready to submit your trip photos to the “brag board” contest when you return home.

Any medications you take regularly.

Sample of Typical Itinerary

Because of our access to 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 fishing and solitude you need for the ultimate fly-fishing vacation. Big trout, an extended season, and low pressure from anglers make for unforgettable fishing. The private river access and eight exclusive boat ramps are a distinct advantage available only to our guests. Wyoming’s property laws don’t allow public wade fishing or boat docking adjacent to private land. Our access provides plenty of wade fishing, relaxing streamside lunches, and access to restroom facilities. We can offer just about any package you are looking for on your adventure, whether it is a single day on the water or multiple days.

Rated 5 out of 5 by from Exceptional service and fly fishing experience! The staff and guides at Crazy Rainbow are friendly, knowledgeable, and professional. My husband and I floated the Grey Reef with Dustin and boated so many fish that I lost count. Dustin knows where the fish are and repeatedly back rowed several sections so we could land more fish. He was patient, helpful (he gave me several pointers on casting and landing), enthusiastic, and put us on fish consistently throughout the day. I can’t wait to book the next trip!

Rated 5 out of 5 by from Always a great day! I recently floated the North Platte with Dustin. I have fished with him several times and every trip has been fantastic with lots of quality fish. Dustin is super friendly, knowledgeable, and hard-working. I will definitely be back and wouldn't hesitate to recommend Dustin and the Ugly Bug/Crazy Rainbow.

Rated 5 out of 5 by from Best Orvis Outfitter We fished four days on the Gray Reef section of the North Platte River in early May, 2021. We stayed at the Crazy Rainbow Lodge. Our group has fished all over the world and we’ve never had better service or a better experience than we did with the Ugly Bug Fly Shop and the Crazy Rainbow Lodge!! Addie Dees, Blake and all of our guides were exceptional. But Laurie- wow! She made us feel like family and took care of us. She went above and beyond to make our experience exceptional. If you want to catch really big fish and to have the trip of a lifetime, this is the best and only outfitter to use on the Platte.

Rated 5 out of 5 by from Great 3 day trip Our group of 6 spent 3 days fishing the Gray Reef, Miracle Mile, and Bighorn River. The action of the Reef was amazing. Private water makes a big difference. The Mile was slow but the fish we caught were large. The Bighorn was mossy but amazing. I’ll definitely come back. The guides were knowledgeable, friendly and patient.

Rated 5 out of 5 by from Great Guide Recently floated the North Platte River with the Ugly Bug Fly Shop in Casper. We stayed at the lodge and floated both days with Mike. He had us in Fish all day long both days we were there. He was very knowledgeable and patient with us, and took the time to teach us along the way. We had a great time fishing and it was a great experience. Highly recommend fishing with Mike at the Ugly Bug in Casper.
