Fly Fishing in Katmai National Park and Preserve: An Angler’s Paradise
Introduction
Nestled in the wilds of southwest Alaska, Katmai National Park and Preserve is a haven for anglers seeking some of the best fly fishing in the world. With its pristine rivers, abundant fish populations, and stunning landscapes, Katmai offers an unparalleled experience for those who love the art of fly fishing. The park is particularly famous for its trophy-sized rainbow trout, massive runs of Pacific salmon, and remote, untouched waters.
For many, fly fishing in Katmai is more than just a sport—it’s an adventure into one of the last great wildernesses. Here, anglers wade into gin-clear waters, cast their lines against the backdrop of snow-capped mountains, and share the rivers with brown bears that feast on the same fish they seek to catch. Whether you are a seasoned fly fisherman or a beginner looking to test your skills, Katmai offers an unforgettable experience.
The Waters of Katmai: Prime Fishing Locations
Katmai is home to numerous rivers and lakes, each offering its own unique fly fishing opportunities. Some of the most famous rivers in the park include:
- Brooks River
Brooks River is perhaps the most well-known fishing destination in Katmai, not just for its world-class trout and salmon fishing but also for its famous population of brown bears. This river is a short but highly productive fishery, running just over a mile between Brooks Lake and Naknek Lake. Every summer, sockeye salmon make their legendary migration up the river, drawing the attention of both anglers and bears alike.
Fishing in Brooks River requires careful planning due to bear activity and National Park Service regulations, but those who
make the trip are rewarded with outstanding dry fly and streamer fishing for rainbow trout that can reach up to 30 inches. During the salmon “egg drop,” trophy trout are often sight-fished feeding behind spawning salmon.
At Royal Wolf Lodge, we fly out to Brooks nearly every day of the season as it is an incredibly consistent fishery and an amazing experience!
- Naknek River
The Naknek River is one of the premier trophy rainbow trout fisheries in the world. Flowing from Naknek Lake to Bristol Bay, it is a relatively short river for how big it is. The Naknek boasts some of the largest rainbows in Alaska, with fish frequently exceeding 30 inches in length. The river is also home to large runs of king salmon, coho salmon, and sockeye salmon.
During the salmon spawn, trout congregate in deep runs, gorging themselves on eggs, making egg patterns and flesh flies highly effective. In the fall, streamer fishing can produce massive, aggressive trout looking to fatten up before winter.
Royal Wolf Lodge has two boats on the Naknek and we primarily fish it early and late in the season utilizing two-handed rods and swinging streamers much like you would for steelhead. The Naknek is not the place you go to catch a lot of trout, but it is the place to go to catch the largest trout of your life!
- Moraine Creek
Moraine Creek is a fly angler’s dream. It is a remote fishery known for its crystal-clear water and abundant rainbow trout that aggressively chase streamers before the salmon arrive, and then transition to gorging themselves on the incredible amount of eggs tumbling down the river. The fish here are often large, hungry, and wild, making every catch an exhilarating experience.
Due to its remote location, Moraine Creek is only accessed via a plane, and its setting is spectacular beneath mountains that typically hold some snow the entire season. It’s also important to be bear-aware, as this creek sees high concentrations of brown bears that also take advantage of the salmon runs.
At Royal Wolf, we typically access the Moraine from mid-July to mid-September using inflatable rafts to float the river. A float down the Moraine just feels like Alaska… big trout, beauty, and bears at eye level.
- Kulik River
The Kulik River is another famous fly fishing destination in Katmai. This short river connects Kulik Lake to Nonvianuk Lake and is known for its consistent population of large rainbow trout in August and September.
Kulik River is easy wading, making it accessible to almost everyone regardless of age or physical shape. While the early season can be productive, we find ourselves fishing it more during the late egg drop. You won’t see any 30 inch trout here, but it’s very likely that you will sight-cast and catch over 30 trout a day.
- American Creek
For those looking for a remote, backcountry adventure, American Creek offers a spectacular float trip experience. This river runs for over 50 miles through untouched wilderness and is famous for aggressive rainbow trout, and char. Floating American Creek allows anglers to access untouched waters, where fish rarely see a fly, making for an exciting and rewarding experience.
Royal Wolf Lodge accesses the American Creek from multiple locations and is one of 6 concessioners that hold the right to use a jet boat on the lower 6 miles of the river. The lower American is renowned for its consistent trophy trout fishing. Trout in the 26-30 inch range are caught by our guests nearly every week of the year on a wide variety of techniques.
This list comprises some of the most well known trout fisheries in all of Alaska, but there are dozens more that we fish routinely that we don’t want to write about for everyone to research on the internet. We love to access small streams by foot, some that are hardly ever fished!
The Best Time to Fish in Katmai
The fishing season in Katmai generally runs from June through October, though the best time depends on the species you’re targeting.
- June – Early July: The early season offers aggressive rainbow trout feeding on baitfish and insects. This is also the best time for dry fly fishing and mousing, as trout actively rise to the surface.
- Mid-July – August: This is prime salmon season, with sockeye, pink (even years), and chum salmon running strong. The rainbow trout and Arctic char fishing is also excellent as fish feed on salmon eggs.
- September – Early October: The fall is one of the best times to catch huge rainbow trout, as they aggressively feed before winter and the trout are at their largest size of the season after feeding on eggs for several months. Streamers can produce some of the largest trout of the year.
Fly Fishing Techniques and Gear
- Targeting Rainbow Trout
Katmai is famous for its large, wild rainbow trout, and different seasons call for different techniques.
- Early Season: Before the salmon runs begin, trout feed aggressively on insects and baitfish. Anglers often have success using dry flies, nymphs, and small streamers.
- During the Salmon Spawn: Trout gorge on salmon eggs, making egg patterns one of the most effective flies.
- Fall Fishing: As salmon die off, trout switch to eating flesh flies, which mimic decaying salmon meat drifting in the current. Large streamers also work well.
- Targeting Salmon
If you’re after salmon, different species require different approaches.
- Sockeye Salmon: Best caught using dead-drifted nymphs or egg patterns.
- Silver Salmon (Coho): Coho are incredibly aggressive and are often caught on brightly colored streamers and topwater flies.
The Wildlife Experience
One of the defining aspects of fly fishing in Katmai is the abundance of Alaskan wildlife. While fishing, it’s common to see:
- Grizzly bears fishing alongside you, especially in places like Brooks River and Moraine Creek.
- Bald eagles soaring overhead, looking for their next meal.
- Moose, caribou, and wolves, which occasionally wander the riverbanks.
Anglers must always be bear-aware and follow strict guidelines for safety, such as carrying bear spray, making noise while moving through brush, and storing food properly.
Planning Your Trip
- How to Get There
Katmai National Park is remote and only accessible by plane. Most anglers fly into King Salmon, Alaska, which serves as the gateway to the park. From there, visitors take a floatplane to the lodge.
