Ask anyone to describe Montana’s natural beauty and you will certainly hear about fly fishing Yellowstone
National Park. The oldest national park in the country and a cornerstone of our state,
Yellowstone welcomes millions of visitors each year to experience once-in-a-lifetime scenery
and wildlife. But YNP’s rivers and lakes beckon a particular group of outdoor recreationists to
travel from states, and even countries, away. Anglers of all experience levels travel from afar
to try their hand with fly fishing Yellowstone at nearly a dozen species of game fish that thrive in the park.
With over 250 miles of road, and plenty to explore off the beaten path, fly fishing Yellowstone
National Park should be on everyone’s bucket list. Here are our tips for fly fishing Yellowstone
on your own this year.
Where to go Fly Fishing in Yellowstone
Yellowstone National Park is home to several notable trout streams that can be organized into
four corners of the park. These include the northwest, northeast, southwest and southeast
sections. These sections are divided by several loop roads that make accessing different areas
of the park much easier.
The northwest section of the park is accessed from either the west entrance in West
Yellowstone or the north entrance of the park near Gardiner. Here the headwaters of the famed
Madison, the Firehole and Gibbon Rivers, are found. Some of the most sought after times to fish
these rivers are in the spring, where thermally-warmed waters are found among chilly
conditions. Firehole River enthusiasts eagerly await the season opener in May to take
advantage of this unique, early-season opportunity.
The northeast section of the park is home to several other famous streams that feed the
Yellowstone River. From the north entrance in Gardiner, anglers can easily drive to stretches of
the Yellowstone, Gardiner and Lamar Rivers. Slough Creek and Soda Butte Creek draw tons of
anglers to the Lamar Valley every summer to chase yellowstone cutthroat and breathtaking
views. A plethora of mayfly and caddis hatches, combined with awesome terrestrial fishing in
late summer, keep anglers coming back year after year to explore this unique backcountry
In the southern half of the Park lies many household Yellowstone attractions, including Old
Faithful, Yellowstone Lake and many beautiful waterfalls. Additionally, the southwest corner of
the Park is home to several remote, less-traveled, fly fishing destinations. These include the
Bechler River and Lewis River, as well as Heart Lake, Shoshone Lake and the West Thumb of
Yellowstone Lake. Some trophy brown, rainbow and cutthroat trout can be found in this area. If
remote fishing is what you’re looking for, don’t shy away from making the beautiful drive down
Finally, the southeast corner of Yellowstone is home to the famed Snake river and Yellowstone
Lake. If you’re looking for yellowstone cutthroat in a remote wilderness setting, don’t shy away
from hiking into the Snake River. Yellowstone Lake is also home to giant, native yellowstone
cutthroat. In the spring, these big cruising fish can be caught in the shallows from shore with
streamers or nymphs.
When to Fish
Yellowstone National Park opens to fishing on the Saturday of Memorial Day weekend (typically
the end of May) and ends the first week of November. Understanding the different types of
water and seasonality is crucial in exploring and fishing this vast wilderness. Our runoff season,
typically from May through the end of June, renders many rivers unfishable. Hitting YNP’s rivers
prior to this runoff event can be difficult to time, but can lead to excellent pre-runoff fishing. This
includes hatches like skwala stoneflies, march browns, caddis and BWOs.
But because the season opener for Yellowstone occurs so close to our runoff season, it can be
safer to plan to fish these waters after runoff or shoot for the lakes during ice-off. Runoff typically
has tapered down in Yellowstone National Park by the first week in July. We then see ample
numbers of summer stonefly hatches, including salmonflies, as well as PMD’s and caddis.
The lakes in and surrounding Yellowstone National Park offer awesome opportunities for
anglers looking to try their hand at big, wild trout. The ice starts receding on many of the Park’s
lakes in May. Many stillwater anglers will take advantage of this opportunity to fish crawfish or
sculpin to hungry, pre-spawn fish.
In addition to Yellowstone Lake, the notorious “gulpers” at Hebgen Lake test dry fly enthusiasts
on long leaders and small callibaetis. Check out the Madison Arm of Hebgen Lake for a
stillwater experience that you’ll remember for years to come.
Bring the Right Gear
The oftentimes adverse conditions in Yellowstone National Park demand the right gear to keep
yourself comfortable, as well as increase your chances of success. Quality waders are crucial for fly fishing Yellowstone in the shoulder seasons — spring and fall. Because there are so many backcountry destinations in the park, gearing up with durable yet lightweight gear is crucial. We wear Simms guard socks and rubber wading boots to abide by the “no felt” rule in Yellowstone. The new Simms Flyweight Access boot is the perfect boot for your Yellowstone fly fishing trip, with a versatile and grippy vibram sole.
A fast-action 5 or 6 wt. fly fishing rod is a perfect rod to cover the majority of fly fishing in Yellowstone.
However, light 3 or 4 wt. rods are a great option for smaller streams with native trout. Some of
our favorites are the Echo River Glass rods for light presentation and rod-bending fun on small
Finally, make sure to be prepared and check regulations before you visit Yellowstone National
Park. Bear spray and other protective measures should be taken when fishing in the
backcountry and can be purchased at local shops, like ours, in and around the Park. A
Yellowstone National Park fishing license is also required, and can be easily purchased online
or in a local fly shop. Visit the Montana Fish, Wildlife and Parks website or the YNP website for more information.
If it isn’t on your list already, a trip to go fly fishing Yellowstone National Park should be on the horizon for any fly angler. The breathtaking scenery, wildlife, and miles of trout-filled water will leave you yearning for another wild fly-fishing adventure.
