The United States has a large number of national parks scattered all across its landscape, but few are as well-known and visited as Yellowstone National Park. This was actually the very first national park in the country and received the designation in 1872.
People tend to be very familiar with the diverse amount of wildlife, the stunning natural scenery, and geysers such as the world-famous Old Faithful.
Now here’s another aspect of the park that is great for fly fishers, and that’s the fact that you can find some wonderful opportunities to enjoy the sport right within the park itself.
The park covers more than 2.2 million acres, is home to Yellowstone Lake, a vast amount of waterfalls, streams, and rivers, and has 16 different species of fish, seven of which are gamefish.
The park isn't just in one state, rather a few as it stretches into Idaho, Montana, and Wyoming. This is the kind of fly fishing destination that isn’t just great for a day trip, but rather a full vacation as you explore all the nooks and crannies of the park.
In this guide we’ll take a look at some of the top spots for fly fishing within the park, as well as some basic advice to ensure your visit is successful and enjoyable.

Finding Your Way in Yellowstone National Park
Because Yellowstone National Park is so large and so diverse it is divided into four main sections, which anglers will want to familiarize themselves with. These sections are the southwest, southeast, northwest, and northeast. You can make you way through them by the roads that connect them all. These are called the Loop Roads in the park. Each section also has its own entrance.
As mentioned the park is home to seven different species of game fish which are: lake, brook, rainbow, cutthroat, and brown trout, as well as mountain whitefish and grayling. Of these species only three are native, the others were introduced through stocking. Let’s take a look at some of the top rivers for fishing in the park.

If you want to get a head start on the fishing season, the Firehole River is typically the first one to be open for fly fishing. Because it is located in the southwest region of the park, the snow is melted here before any of the other major rivers.
This is an interesting area to fish as the water is made up of a spring creek and a freestone stream. The reason the snow is able to melt much faster here is that the geysers empty into this river, which of course warms it up. This stream is at its peak in the early spring months and then isn't as great as you move into summer. At this point the water gets too warm for the trout.
As for the surrounding scenery, much of this river flows through quite serene meadows. Be prepared for many riffle areas and weeds. Some areas flow quite slowly while others are fast. It makes the river interesting and it forces you to use various skill levels and techniques. The typical fish you'll find here are brown and rainbow trout.

Lamar River Valley
Huge boulders in the Lamar River Canyon provide ample places for cutthroat trout to hide
If you plan to visit the northeast of Yellowstone then the Lamar River can make for an excellent option. The river itself sits in a valley and feels like a beautiful and quiet oasis.
This is quite a long river that actually begins in the Absaroka Mountains. The river has different sections and each has their pros and cons. Check out our DIY Guide to Fly Fishing the Lamar River for more information on this fishery.

Several other rivers in the Northeast part of the park hold lots of trout and should be on your bucket list including Soda Butte Creek. It is a tributary of the Lamar River that tends gets a lot of attention but is worth it. Typically you'll be fishing for cutthroats but you can also find cutbows and rainbows.
Other areas of the river include the Upper Lamar River, where the fish are small and but plentiful, Cache Creek where you can find moderately sized cutthroat, the Canyon Section where the water can run fast making the fishing a bit more difficult, and the famous Slough Creek which can yield some wonderful fishing opportunities.

While the Gibbon River isn't huge you can find areas that yield a variety of rainbow, brook, and brown trout. Occasionally you can find grayling here as well. Depending on which section you head to the river may be running quite fast as there are many pockets where the water is rough. With that said anglers love how challenging the Gibbon can be and find the conditions thrilling and enjoyable.
The various sections of the river are the Lower Gibbon Meadows, the Upper Gibbon River, Gibbon Falls to Lower Meadows, Gibbon Meadows, Gibbon Meadows to Gibbon Falls, Norris Meadows, and Elk Park.

Planning Your Fishing Trip to Yellowstone
Yellowstone National Park has a set season for fishing which begins Memorial Day weekend (the Saturday) and lasts until the first Sunday in the month of November. The public is able to fish during the season from sunrise to sunset each day. With that said there may be areas that are closed from time to time, this is due to water levels and even the fish population. Should a certain area be low on fish, it may close to the public temporarily so the fish have a chance to rebound.
Most people find that spring and fall are the best times for fishing in the park, but that’s not to say the summer isn’t great as well. In fact, some would argue that August is the best month as all the rivers are open by this point.
If you plan to visit at the start of the season in May, typically the only river without snow is the Firehole, so it's a great place to start. It's not until mid-June that the Madison and Gibbon Rivers will lose their snow and then become another option. You'll have to wait until the start of July for all the rivers to be totally free of the snow.
Best Flies for Yellowstone National Park
There are a number of hatches that happen in the park on a seasonal basis. They can be divided into spring, summer, or fall hatches. They also tend to differ from river to river.
All the main types of hatches occur, which are mayflies, stoneflies, caddis flies, and midges along with others. Terrestrials including grass hopper, ants and beetles are also abundant in the summer.
With that said, July tends to be the absolute peak month for all the various hatches.

Yellowstone Fishing Regulations
If you plan on bringing a boat into the park for fishing, you'll need to first ensure your boat is permissible. If it is, you'll then need a boat permit. Shore fishing is available in a number of locations, so you don’t have to have a boat in order to enjoy the park. This means one less permit to have to worry about.
Yellowstone Fishing Restrictions
There are also some pretty strict restrictions on your hook, lure, and tackle when fishing in Yellowstone National Park. There is only one rod permitted per angler and you are required to use lead-free artificial lures only.
You won't be able to use weighted jigs, split-shot, or soft-lead weighted. Your lure may only have one hook and must be barbless.
Be warned that there are also restrictions and rules on limits, catch and release areas, and areas you are not allowed to release fish that are caught. You’ll want to go over all the specifics before you start your fishing.
