Summary Trip Description |

Tucked in the northeast corner of the Park and nestled against the spectacular and scenic Absaroka Beartooth Wilderness lies Slough Creek – home to the quintessential Yellowstone experience. Located in famous Lamar Valley, Slough Creek is a picture-perfect expansive valley with towering mountain vistas with room to roam.

If the open western landscape with its distant vistas – dotted with wild-roaming bison, grizzly bears, and wolves – is your thing, then this trip is for you. Our trip north into the heart of Slough Creek, following the meandering flow of the lazy creek, is eye-candy for those drawn to exceptional wild places and their inhabitants.

As we make our way through lush meadows and gentle rises, we leave the bustle of modern life behind. This is nature as untamed and pristine as it gets. In this vestige of the American West, there are no fences; wild things roam as they have for eons. This trek is not about conquering mountain tops, but rather an excursion into what it means to be home in the wild. We’ll fall asleep gazing at nighttime stars, embrace the sound of rejuvenating water, and ponder deeper meaning as we listen to distant howls of wolves. Yellowstone’s abundant wildlife is as famous as its geysers, and this area in particular offers some of the best wildlife watching opportunities. To top it all off, Slough Creek is Yellowstone’s finest fly-fishing destination and among the very best blue-ribbon wild trout fisheries in the West. We invite those with an adventurous spirit and who love to cast a fly, to join us on this gorgeous and inspiring journey. This is a fly fishing experience that only a few people will ever have, and one you will undoubtedly never forget.

Fly Fishing Slough Creek |

Slough Creek is a world famous tributary to the Lamar River just down from Soda Butte Creek. Slough Creek ranks among the most famous trout fishing locations in the western United States. Slough Creek has probably glossed the cover of most fly fishing magazines ever published. It’s one of those legendary places that is uniquely different from most other trout stream. Slough Creek is revered in the fly fishing world, and every angler owes it to themselves to test their dry fly skills against some incredibly large native cutthroats.

The native Yellowstone Cutthroat Trout thrive here and they are both big and abundant. Most of the fishing is done with dry flies. Slough Creek is generally divided into 4 meadows, named, from top to bottom: Third, Second, First, and Lower. The 1st, 2nd, and 3rd meadows have good populations of native Cutthroats that average in the 14”-16” class, with fish over 20” caught on a regular basis.

On this trip, we will be fishing early-mid July, so the fish should be less wary, as compared to late summer and fall. Slough Creek spends much of it’s time meandering through meadows, so the insect life is abundant. Both terrestrials and mayflies congregate here and make up most of the food that helps those cutthroats grow so larg

e. Pale Morning Duns can hatch in great numbers on an average summer day. They hatch best during the mid morning and evening. Packing in, is the key here, you will want to be on the water early and late. Blue Wing Olives, or Baetis, will hatch in substantial numbers on cloudy or rainy days. This hatch is usually on during the afternoon. Yellowstone is known for good populations of caddis and Slough has a exceptional amount as well. Slough Creek also has an extremely large population of terrestrials. Because of the meadow setting, grasshoppers are numerous, as well as ants and beetles.

As far as the fishing goes, our guides will be there to give can give you as much or as little advice and help as desired. We will pack along a wide selection of flies to match the hatch and terrestrials found in this area.
