About
Armstrong Redwoods State Natural Reserve offers a majestic journey into an ancient redwood forest. This tranquil 805-acre sanctuary, nestled in Sonoma County, California, preserves magnificent coast redwoods (Sequoia sempervirens) that once covered vast stretches of the region. It stands as a living testament to the primeval redwood forests, inviting visitors to immerse themselves in unparalleled natural grandeur.
Within this awe-inspiring grove, visitors can marvel at some of the world's tallest and oldest living things. Highlights include the 1,400-year-old Colonel Armstrong Tree, a silent witness to centuries of history, and the towering Parson Jones Tree, which stretches over 310 feet towards the sky, taller than a football field is long. Unique features like the burl-laden Icicle Tree showcase the intriguing formations found on redwoods, while the lush understory thrives with redwood sorrel, ferns, and, in spring, vibrant trillium and redwood orchids, all sustained by the temperate rainforest climate and frequent fogs.
A visit to Armstrong Redwoods is an escape from the everyday, offering inspiration and a rare opportunity for quiet reflection amidst these gentle giants. The reserve provides a profound connection to Earth's ancient past, leaving visitors with lasting memories of the forest's serene beauty and the sheer resilience of these towering trees.

The story of Armstrong Redwoods State Natural Reserve begins in the 1870s, when lumberman Colonel James Armstrong, despite his profession, recognized the inherent beauty and natural value of this specific redwood grove. He took the pioneering step of setting aside this portion of the forest for preservation. Following his death, his daughter and the Le Baron family passionately continued his vision, spearheading public campaigns to ensure the grove's protection. Their dedicated efforts led to the purchase of the grove by Sonoma County in 1917. Management was later transferred to the State of California in 1934, and the area officially opened to the public as Armstrong Redwoods State Park in 1936. This preservation was crucial, as an estimated 95% of California's old-growth redwood forests were lost to logging during the 19th-century Gold Rush, making the survival of Armstrong Redwoods particularly significant. In 2020, the Walbridge Fire impacted areas of the park, but the core old-growth grove remained largely intact.
What to do here
Walk the accessible nature trails, enjoy a picnic amidst the redwoods, observe the unique redwood ecosystem, and visit the visitor center. Seasonal horseback riding is available on specific trails in the summer, though visitors need their own horses.
Seasonal info
