Stone Lagoon Visitor Center is a cozy place to relax and learn about Humboldt Lagoons State Park. It’s just west of Highway 101 at mile marker 115.3. It’s open daily from about 9 a.m. to 6 p.m.
The Humboldt Lagoons State Park brochure contains valuable information about the park’s cultural and natural history, as well as travel tips.
More information is available on the websites of the Redwood Parks Association, Coastwalk (which offers multi-day guided hikes through Humboldt Lagoons and other coastal parks in California), and Save the Redwoods League.
