Mad River Slough: Riparian Habitat and Coastal Estuary Trails

Near Arcata and McKinleyville along Humboldt Bay, Mad River Slough forms a scenic estuary and riparian corridor with trails through wetlands and forests. This quiet area offers creekside wildlife viewing and peaceful exploration in a recovering estuary ecosystem.

A Riparian Estuary and Wetland Mosaic

Mad River Slough blends tidal channels, freshwater inflows, salt marsh, and riparian forests (willows, alders). It supports migratory birds, herons, otters, salmonids, and seasonal wildflowers; the slough's dynamic tides sustain diverse invertebrates and fish nurseries.

Adventure With a Conservation Conscience

Short trails along slough edges for birding and nature walks; access from Mad River County Park or nearby pullouts.

Access is open: free roadside parking, sunrise to sunset, pack out waste, stay on paths. No major facilities; respect private land and tides.

Mad River Slough delivers Humboldt riparian habitat hiking in estuary beauty. For quiet walkers and birders seeking creekside life, the trails reward gentle presence; a serene coastal corridor.
