Spectacular Back Drop

Fremont Canyon is one of Wyoming’s (somewhat) best kept secrets and is the perfect location if you are looking for a spectacular backdrop for some of the best trout fishing in the region.

Famous Explorer Fremont

Fremont Canyon was named after General John C. Fremont after he came to explore the canyon in the mid 1800’s. On August 24, 1842, Fremont attempted to navigate the canyon by boat. Ultimately, the boat capsized, and all provisions were lost, which forced him and his men to make their way to St. Louis on foot. This is a great segway to mention that Fremont Canyon is only accessible by foot, which makes it a great experience for any angler who is up for a little bit of challenge and adventure.

Rock Climber Delight

The views and fishing aside, another spectacle of Fremont Canyon is the rock climbers. As you drive over the bridge of the canyon, you may see rock climbers rappelling down the canyon’s 200-to-500-foot walls, and often many of them are fishing while they are doing it. Once you continue over the bridge, you will run into Cardwell Access Area. Here is where you are able to park your vehicle and start the short walk down to the meadow.

Canyon Fly Fishing

This unobstructed access to the river is a great place to get your casting in order without having to worry about the dreaded back cast snag. From here you will see the mouth of the canyon. When flows are around 75 cfs (which is typical for this stretch), you are able to cross the river and enter into the canyon. There is some rock hopping involved, so be sure to have proper footwear. The more you hop back into the canyon, the less pressure those fish have had, which can make for some very productive days. This stretch is typically nymphed, but there is some dry fly opportunity in the early mornings and late evenings.

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.

    Destination Travels

    Crazy Rainbow Fishing Around The World

    Come travel the world with Crazy Rainbow Fly Fishing Guides. We travel to exotic places around the world for exciting fishing trips. Schedule early Crazy Rainbow Destination Travels are limited opportunities. Each trip is only offered once per year to every other year.

    The River of Dreams

    Travel the Magic Waters Patagonia, our main and first fly fishing operation in Patagonia, we are always looking for new adventures, and always looking to find new waters for our friends and clients. For long time we were looking at Blanco River. We were wondering about the fishing and mainly about how to set up an operation in this pristine and untouched 30 miles of river. So, between Eduardo Barrueto and Andi Manstein we decided to go forward and start setting up this fantastic dream, that we called The River of Dreams.

    Caribbean Fishing

    Travel to the Grand Slam Fishing Lodge is like an exclusive resort that happens to be run by fishermen, for fishermen (and their non-fishing companions). Situated on a narrow, palm tree-studded strip of sand, the lodge faces the Caribbean on one side with the lagoon lapping on the other side. So, you get great sea views plus easy access to Ascension Bay with our lagoon dock.

    Tsimane Fishing

    Travel to the Agua Negra Camp is a remote yet luxurious tent camp/lodge perched on a bluff overlooking the Secure River. Roughly 100 yards away is the small native village of Agua Negra, which makes this camp by far the most culturally rich of the Tsimane experiences. Here anglers will enjoy very comfortable double occupancy safari tents with attached baths as well as the comfort of the main lodge building where drinks and meals are served. The fishing will be done on the main Secure as well as on the Agua Negra River. The Agua Negra is smaller and offers not only big dorado but the region’s most forgiving terrain as well as the greatest diversity of species including large pacu, pira pita and the elusive striped catfish known as surubi.

    Schedule Crazy Rainbow Destination travels today to experience fishing of a lifetime.
