Within the river, chum, coho, and pink salmon abound during the spawning season, drawing bald eagles in profusion. I have counted 100 eagles from the seat of a Boston whaler anchored just offshore in the canal near the mouth of the Endicott River, their clumps of dark feathers fluffed against the drizzling rain. There are no trails, but sturdy backpacking will take you up along the waterway and over a low pass into Glacier Bay National Park. You will probably see no other humans. Avalanche danger runs high in winter.
Camping is unrestricted, but building campfires is difficult work due to persistent rain.
Firearms are permitted.
