Slough Creek | Fly Fishing Llama Basecamp

Yellowstone National Park

Llama trips in Yellowstone advertised on this site are conducted by Llama Adventures Unlimited LLC, DBA Access Wild, an authorized concessioner of the National Park Service.

Yellowstone National Park is divided into 4 different quadrants each with its own beauty and unique character – Northwest, Northeast, Southeast, and Southwest. We’ll focus on the Northeast section of Yellowstone with a Fly Fishing Llama Basecamp.

The Northeast section of Yellowstone is a fly fisherman’s dream. The incredible scenery and fly fishing are world class bringing people in from around the world to visit the famous and most popular streams – the Lamar and Yellowstone Rivers, Slough Creek and Cache Creek – all home to the native Yellowstone cutthroat trout.



Slough Creek | Fly Fishing Llama Basecamp

July 13-16, 2020 | 4-day/3-night
10+ Miles | Easy/Intermediate


A tributary to the Lamar River just down from Soda Butte Creek, Slough Creek has been heard around the world as an excellent fishery in a spectacular setting. Beautiful meadows stretch along the valley floor surrounded by lush forest and towering rocky mountains. There are three meadows in total before the trail and creek exit the northern boundary of the park at the private Silver Tip Ranch. The ranch provides horse drawn wagons for its lodge guests following a well worn double track all the way to the ranch. All three meadows offer incredible scenery and great fishing. The deeper you go the less and less people you’ll see.

Slough Creek is home to native Yellowstone Cutthroat trout, rainbow trout, and hybrid cutbow trout, all averaging 14″-18″ with some exceeding the 18″ mark. Interestingly, YNP has been working to maintain the native Yellowstone Cutthroat and require all rainbow trout, brook trout, and identifiable cutthroat x rainbow trout hybrids must be killed.

The fish in Slough are plentiful and you’ll use nothing but dry flies.  In mid July look to use Drakes, PMD’s and midges plus some terrestrials. There’s nothing like casting a dry fly in Slough. The views are incredible, there’s wildlife all around and you have eager native Yellowstone Cutthroat chasing your fly.

Since Slough Creek is sought after from anglers around the world, the backcountry campsites are in high demand. Yellowstone NP limits the campsites to just three nights and we’ll only be allowed two weeks out of the year giving opportunities to other outfitters and the general public. This is a once in a lifetime opportunity. Fish Slough Creek with us.

What to Expect

This llama trek is an out and back beginning at the Slough Creek TH. The trail begins by climbing a short steep grade before descending down to the first meadow after 1.5-2 miles. Continuing along the eastern side of the meadow, you’ll approach our camp after 5 miles. Great opportunities for wildlife viewing of bison and potential for grizzly bears. On our approach we’ll have opportunities to fish our way to camp through the first meadow.

Our camp sits right along the banks of the Creek. Once camp is set there will be plenty of opportunities to fish around camp or head off up stream. Each day we’ll have the chance to set out hiking up stream to fish the second and even third meadows.
