KASILOF RIVER FISHING TRIPS
LOCAL GUIDES WHO KNOW THE WATER
Most people come to the Kenai Peninsula thinking about the Kenai River. That’s understandable — the Kenai is world famous and deserves every bit of its reputation. But ask any guide who’s spent serious time on both rivers and you’ll hear the same thing: don’t sleep on the Kasilof.
Seventeen miles of glacially-fed water running from Tustumena Lake to Cook Inlet. Drift boat only. Quieter, wilder, and in recent seasons — especially for king salmon — fishing as well as anything on the peninsula.
The guides at RiverRise Fishing Guides have been running fully guided fishing trips on the Kasilof River for over 25 years. We know where the fish hold, how the tides influence the lower river, and what presentation is working on any given morning. Every Kasilof River fishing trip we run is built around current conditions — not a fixed itinerary.
Whether you’re chasing early run kings in May, sockeye limits in July, aggressive silvers in August, or late season steelhead in September — we’ll put you in the right place at the right time. Fully guided trips for all skill levels. Families, first-timers, and experienced fly anglers all fish with us. Let’s get you on the water.
THE KASILOF LINEUP
Salmon & Steelhead – AlL In ONE River
Kasilof River King Salmon Fishing.
The Kasilof River — known to most as “Kenai’s Little Brother” — doesn’t get the same attention as the Kenai when it comes to king salmon, but it should. Over the last several seasons, as the Kenai River king run has seen pressure and regulation changes, the Kasilof king run has held steady. Some years it’s been the stronger fishery of the two.
We begin fishing for Kasilof King Salmon around May 16th each season. The early run is primarily made up of hatchery fish — generally harvestable, ranging from 8 to 40 pounds, with smaller fish pushing in first and the bigger ones following behind. That early run lasts through mid to late June. Immediately after, the second run arrives — larger adult wild Kasilof kings that hit harder, run longer, and in recent years have had days of harvest when ADFG regulations allow it.
Nearly all of our Kasilof king salmon fishing is done from our 20-foot Willie Drift Boat on the lower river, using back-trolling with Kwikfish and MagLip plugs or back-bouncing with custom-cured salmon eggs. The take-down of a fresh ocean-run king salmon is something you don’t forget. They’ll either have you booking your next Alaska trip before you’re back at the ramp — or losing sleep over the one that got away.
Kasilof River Sockeye Salmon Fishing.
The Kasilof River Sockeye Salmon begin showing up around the start of June, with the peak of the run arriving as early as mid-June in strong years. From the second week of July through the first week of August, you can almost always count on limits of these incredible fish.
Sockeye don’t feed aggressively in freshwater, so the approach is different from what most anglers are used to. We use a technique called “lining” — working a longer leader and fly through the fish’s traveling lanes and letting the current do the work. Your guide sets you up and walks you through every step. It’s one of those techniques that makes complete sense the moment you hook your first fish.
A typical Kasilof sockeye morning starts with an early float down to one of our proven traveling lanes, followed by waiting for the fish to move through. Some days you limit in 10 minutes. Some days it takes a couple of hours. Either way it’s the kind of trip the whole family enjoys — accessible, exciting, and the fish are some of the best eating you’ll find anywhere in Alaska.
Kasilof River Silver Salmon Fishing.
If you’re looking for an aggressive fish that shows up in big numbers — look no further than Kasilof River silver salmon. They’re built like kings, fight like they’re angry about it, and tend to show up on the Kasilof before they push into the Kenai — giving our clients first crack at the early run every year.
The Kasilof holds two distinct silver runs. The first starts around the end of July and runs through August. The second, larger run pushes in around the start of September and can hold strong through mid-month. As water levels drop in late September, fish stack in the deeper pools and the fishing gets serious. Second run silvers on the Kasilof commonly run 10 to 15 pounds — strong, bright fish in cold water.
We catch silvers using a variety of methods depending on what they’re responding to that day: back-bouncing cured eggs, back-trolling plugs, casting jigs and spinners, and topwater flies when conditions are right. Finding a school of silvers held up in a pool and experimenting with presentations until you crack the code — that’s one of the best afternoons you can have on this river.
Kasilof River Steelhead Fishing.
Late season on the Kasilof means steelhead — one of the most coveted catches in freshwater fishing anywhere in the world. Wild Kasilof River steelhead are catch-and-release only by regulation, and we fully support that. These fish are handled with care, photographed well, and released with every precaution.
We fish steelhead primarily with fly rods, working the deeper runs and pools where late-season fish hold as water temperatures drop. If you’re a fly angler looking for a legitimate Alaska steelhead experience on a river that doesn’t get the crowds — the Kasilof in September is worth planning a trip around.
KASILOF RIVER FISHING TRIP OPTIONS
HALF-DAY TRIPS
The Kasilof River is an excellent half-day option for sockeye and silver salmon. Floats are manageable, fish are accessible, and a productive morning or afternoon on this river is hard to beat. Half-day trips run approximately 4 hours with morning and afternoon start times available. Great option for families with younger kids or anyone who wants an exciting session without a full day commitment.
FULL-DAY TRIPS
If you want a full day on the Kasilof, we’ll give you one. All 17 miles of this river fish well when the runs are moving through, and a full day gives us the flexibility to follow the fish wherever they’re at. Full-day trips run 8 hours. Strongly recommended for king salmon — you want maximum time on the water. During prime sockeye season, don’t be surprised if the grill comes out and we cook fresh fish on the riverbank. There’s nothing fresher than that.
GROUP & CORPORATE TRIPS
Have a large family, a group of friends, or a corporate event? We can handle it. Multiple boats, multiple guides, plenty of room for everyone. Reach out and we’ll build the right setup for your group size and goals.
FAMILY-FRIENDLY KASILOF RIVER FISHING
The Kasilof River is one of the best places on the Kenai Peninsula to get a family on the water. The fishing is accessible, the scenery is wild and beautiful, and the sockeye run in particular has enough consistent action during peak season to keep everyone engaged — including kids who’ve never held a rod.
We’re patient, we’re experienced with beginners, and we genuinely enjoy putting first-timers on fish. Whether your group is all seasoned anglers or a mix of experience levels, everyone gets the same quality of guidance.
