Humboldt Bay and its eastern arm, the Mad River Slough, are a magnet for migratory shorebirds, ducks and geese. Once a logging channel carved to move timber to nearby mills, the slough has softened into a wildlife refuge—an intimate, bird‑rich waterway ideal for watching tides, flocks and transient shorebird concentrations from a kayak. This trip is tailored to bird enthusiasts; bring binoculars for the best views.
