EUREKA KAYAK FIELD GUIDE
Paddling the Mad River Slough: A Quiet Kayak Window into Humboldt’s Migratory Birdlife
A focused, three‑hour guided kayak outing from Arcata that puts birders and beginning paddlers into the eastern edge of Humboldt Bay where shorebirds, ducks and geese concentrate.
Paddling the Mad River Slough: A Quiet Kayak Window into Humboldt’s Migratory Birdlife.
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.
