Headwaters Forest Reserve preserves some of the last undisturbed old-growth redwood stands on Earth. Located near Humboldt Bay in California, this 7,472-acre reserve offers visitors a profound connection to an ancient ecosystem that was nearly lost. It stands as a testament to successful conservation efforts, protecting not only monumental trees but also a diverse array of unique flora and fauna.
The reserve is a critical habitat for several threatened species, including the elusive marbled murrelet, which nests in the old-growth canopy, and the majestic northern spotted owl. Its pristine stream systems, including the South Fork Elk River and Salmon Creek, provide vital spawning grounds for coho and Chinook salmon, as well as steelhead and cutthroat trout. Visitors can explore various trails, such as the Elk River Trail, offering glimpses into these sensitive ecosystems and the towering redwood trees that define the landscape. The Headwaters Education Center, located along the Elk River Trail, offers insight into the reserve's history and ecology.
A visit to Headwaters Forest Reserve is an immersive experience into a truly special natural wonder. It offers a unique opportunity to witness the grandeur of millennia-old redwoods, appreciate the delicate balance of a thriving forest ecosystem, and learn about a remarkable conservation success story. The serene atmosphere and awe-inspiring scale of the redwoods make it an unforgettable destination for nature lovers and those seeking peaceful reflection.

Stay on designated trails
To protect the delicate ecosystem and wildlife, it is crucial to remain on marked trails.
Bring water and snacks
Especially for longer hikes like the Elk River Trail, carry sufficient water and any necessary snacks.
Dress in layers
Coastal redwood forests can have variable weather; dressing in layers will help you adapt to changing temperatures and potential fog.
