Yellowstone National Park | Fly Fishing Llama Basecamp


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. All llama trips in Yellowstone are conducted under the Concession Contract YELL168-16, Llama Adventures Unlimited LLC, DBA Access Wild, an authorized concessioner of the National Park Service.


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.

Lamar River Valley

Ahhh, the Lamar. What a beautiful sight! The panorama views from the easy trail are mind boggling. Its incredible to see such a beautiful wilderness landscape untouched and virtually undisturbed as you venture far into the backcountry. Bison, antelope, deer, grizzlies and wolves frequent the area free to roam as you view them from afar in their world. At 3.3 miles Cache Creek feeds into the Lamar and the location of the first stock camp. After the next 7 miles, you’ll approach the joining of Miller Creek and the next stock camp.

This trek is an out and back with great opportunities for viewing wildlife, photographic hikes, and lounging at camp sipping on some wine thanks to the llamas. Fly Fishing opportunities are plentiful at both stock camps and demand 2 nights at each making it an incredible 5 day Lamar Valley fly fishing experience. Not too many people can say they’ve fished Lamar backcountry. Even less have said it with the support of llamas.

Slough Creek

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.

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 a stock camp after 5 miles. Great opportunities for wildlife viewing of bison and grizzly bears in the meadows while getting your line wet on the famous Slough Creek. Stay here for two nights and back or move a few miles down for another few nights.
