Guided Fly Fishing In Yellowstone National Park

At Fish the Fly Guide Service, we focus on fishing the southern half of Yellowstone National Park. We fish famous rivers like the Firehole and Snake but there is much more to explore in the world’s first national park.
Once you step off the beaten path where most of the tourists are, the real Yellowstone reveals itself.

Steam rises from the hundreds of geysers and hot springs, while herds of Bison and Elk dot the landscape as you look for the next bend in the river to drop your fly.

Fly Fishing Yellowstone National Park

The Firehole River is easily one of the most unique rivers holding trout on the planet. Boiling hot springs, bubbling geysers, and mud pots line the river and it’s common to see Bison and Elk feeding along its banks. The Firehole is wade fishing and fly fishing only with epic hatches of Mayflies and Caddis. These hatches are great to teach those new to the sport but also offer plenty of challenges for the dry fly angler.

Lewis Lake is a beautiful backcountry lake that offers some of the best stillwater fishing in the region for Brown and Lake trout. Ice off arrives before or just after Yellowstone opens to fishing on Memorial Day weekend. The shallows are teeming with cruising trout and they are hungry! Mayfly and terrestrial hatches keep the brown trout looking to the surface throughout the Summer. Well fed Lakers and Brown come back to the shallows as they spawn in late September through the end of October.

Yellowstone is a great place to swing wet flies, fish dry flies, nymphs, or streamers at any time in the season. Technique will depend on the fishery and the time of the season. Mayfly and Caddis hatches, especially early and late in the season, offer match the hatch conditions.

Best Time
Fishing season opens on the Saturday of Memorial Day weekend and typically the Firehole is the best option with great hatches. Mid to late June brings more snowmelt and Lewis Lake and a few creeks fish well. July-September is consistent for dry fly action on the major rivers and also the small creeks and lakes. October brings spawning brown trout on the Madison and Lewis Rivers. These rivers and Lewis Lake are a great option until the Park closes the first weekend of November.
