Susitna River: Rafting, Fishing, and Wild Alaska Scenery

Why the Susitna River Stands Out

The Susitna River drains the southern slopes of the Alaska Range and flows 313 miles south to Cook Inlet, carving through boreal forest and glacial outwash plains. Its braided channels, clear tributaries, and reliable salmon runs make it one of Southcentral Alaska’s premier waterways for both experienced anglers and first-time visitors seeking remote float trips without weeks of planning.

Best Time to Visit

Prime season runs from mid-May through mid-September. Early June brings the first king salmon, while July and August offer overlapping runs of sockeye, chum, and silver salmon plus longer daylight for extended floats. September delivers fewer bugs, brilliant fall colors, and lower water levels that simplify navigation for novice paddlers.

Activities on and Around the River

Fishing

Drift boats and jet boats launch from several Mat-Su access points to target king salmon in May and June, then switch to silvers later in summer. Many visitors combine fishing with wildlife viewing; brown bears and moose frequent the riverbanks at dawn and dusk.

Rafting and Kayaking

Multi-day floats from Talkeetna downstream to Deshka Landing or even to Cook Inlet showcase changing scenery from glaciated peaks to tidal flats. The river’s Class I–II water is suitable for intermediate paddlers when levels are normal, though wind and braided channels require route-finding skills.

Wildlife and Scenery

Keep binoculars ready for bald eagles, trumpeter swans, and Dall sheep on nearby ridges. The river corridor also serves as a gateway to Denali State Park trails and the Little Susitna River for day hikes or shorter paddles.

Getting There

Fly into Anchorage, then drive north on the Parks Highway. Popular put-ins lie near Talkeetna (mile 98–100) and at the Susitna Landing public boat ramp. Most visitors arrange shuttles with local outfitters for one-way floats, returning by road or floatplane from remote take-outs.
