If you’re looking for an unforgettable King Salmon fishing experience, the Kasilof River is one of Alaska’s best-kept secrets. Flowing from Tustumena Lake to Cook Inlet, this glacial-fed, drift-boat-only river provides a peaceful and productive setting for targeting massive Chinook (King) Salmon.
At Kenai Fly Fish, we specialize in guided King Salmon trips on the Kasilof, using expert techniques and local knowledge to put you on the fish. Whether you’re a seasoned angler or new to Alaska fishing, we’ll ensure your day on the river is thrilling, action-packed, and unforgettable.
Why Fish for King Salmon on the Kasilof River?
While the Kenai River gets most of the attention, the Kasilof River offers a quieter, more secluded fishing experience with big rewards. Since it’s a drift-boat-only river, you won’t hear the hum of jet boats or compete with heavy motorized traffic—just the sound of the water, the birds, and the thrill of a massive King Salmon on your line.
✅ Strong hatchery and wild King Salmon runs
✅ Less fishing pressure than the Kenai River
✅ Drift-boat-only waters for a peaceful experience
✅ Excellent early-season King fishing
If you want to fish for giant Kings in a quiet, scenic Alaskan setting, the Kasilof River is the place to be.
How Big Do King Salmon Get on the Kasilof River?
The Kasilof River is home to both wild and hatchery-raised King Salmon, with fish commonly weighing between 15 to 40 pounds. However, some Kings reach well over 50 pounds, offering an epic battle and a once-in-a-lifetime catch.
Early in the season, the first run consists primarily of hatchery King Salmon, which can be retained depending on regulations. The second run brings wild, naturally spawning Kings, which are typically catch-and-release only. Regardless of the run, these fish are powerful, aggressive, and put up an incredible fight.
Best Time to Fish for King Salmon on the Kasilof River
🎣 May – June: The first King Salmon run begins, with strong hatchery fish arriving early. These Kings are hard-fighting and often retainable, making them a favorite for anglers looking to take home a prized catch.
🔥 July: The second run of wild Kings enters the Kasilof, offering some of the best King Salmon fly fishing opportunities of the season. These fish are catch-and-release, but the experience of battling a wild Alaskan King is second to none.
If you want to hook into a powerful King Salmon, the best time to fish the Kasilof is from mid-May through mid-July.
