Ugly Bug Fly Shop, WY

Orvis-Endorsed Fly-Fishing Outfitter in Casper, Wyoming

Ugly Bug Fly Shop, WY


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. Wingshooting season is September 15 through March 31.

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. This is a 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.


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.


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.

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.

    Fishing heaven! - 6/6/2014
    By: from Charleston, WV, USA

    We've booked with Crazy Rainbow for 9 years straight and it gets better every year! We normally have groups of 8 and up to 12 some years. We just finished a June trip and it was the best one yet. They offer an all inclusive service with terrific fishing, accomodations, and meals. We were catching 60 to 75 trout per boat with various levels of experience among our fishermen. The guides were extremely helpful with sharing their knowledge. These guys are a lot of fun and very professional at the same time. They treat the trout like babies and will net, take them off, and tie on flies when needed to get you in the water so all you have to do is pull them in! Great experience overall and anyone who books with them will not be disappointed. It's easy to see why they won the Orvis Outfitter of the Year for 2014.

    By: from Broomfield, CO, USA

    As mother nature would have she blew out the grey reef. Blake and Sarah were both disappointed but made sure that we caught fish at a couple of other places they know of. Best customer service around.

    Perfect Fishing Trip! - 5/23/2014
    By: from Denver, CO, USA

    I recently went on a 3 day fishing trip with the Ugly Bug fly shop, and was amazed at how great everything was. Our guide, Jake, was the best, I've never seen so many fish, or caught so many, and the meals/accommodations were perfect. I can't wait to go back. Keep up the great work!

    Awesome day on the Reef! - 4/29/2014

    My dad who was visiting from Indiana and I fished with Sarah. We floated the upper section and had a blast. Sarah was awesome in all ways - good on the sticks, great knowledge of the water and bugs, and great personality. I genuinely felt like she was having almost as much fun as us. We caught a silly amount of fish, but it would have been a great with a fraction of what we caught. Would recommend her in a second.

    great fishing despite warm water - 4/2/2014

    My friends and I spent a weekend on the North Platte guided by Jameson Frank. The hot summer had left the water still warm, but we had great fishing, thanks to Jameson's expert knowledge of the river and calm, competent guidance. I would recommend him to anyone who loves to catch fish. In fact, we are going back in the Spring.

    Cold weather, smoking hot fishing.... - 4/1/2014

    My brother and I fished with Ty Hallock on the 22nd and 23rd of March. The river was in the midst of the annual 10-day flush, which had begun 5 days prior. The weather was cold on the 22nd with snow, clouds, and temperatures that stayed in the low-to-mid 20s. The fish did not care. Ty had us on them from the time we shoved off the bank to the time we took out. The temperature was 22 degrees when we took out, incidentally. Day two found the weather much better as the sun came out and temperatures rose to the mid-40s. Saturday was good, Sunday was nuts. We caught fish non-stop and the fish were hot. I think the sunshine perked them up a bit versus 22 and snow. Ty's knowledge of the river led to our having a great experience under poor conditions on Saturday. Sunday was nothing short of silly. Thanks!

    By: from denver

    Crazy Rainbow fly fishing is one of the best outfitters in the country in my opinion. Superb service, reasonable prices coupled with expert guides. Jameson, Ty and others make each and every yearly trip memorable. This year was no exception. You really gotta try these guys and see what you're missing. Professionals, courteous and always willing to go the extra mile to make sure you have fun and a good day on the river. thanks guys what a great day!
