This temperate rainforest oasis offers towering giants, educational experiences, and accessible nature walks—making it a must‑visit destination for families, photographers, hikers, and eco‑friendly travelers alike.

What Makes Armstrong Redwoods Unique

Armstrong Redwoods is one of the largest remaining old‑growth redwood groves in Sonoma County. It protects over 800 acres of Sequoia sempervirens. Here you’ll find stunning natural monuments. There is the towering Parson Jones Tree (over 310 ft tall). You can also see the ancient Colonel Armstrong Tree (over 1,400 years old). Additionally, admire the mysterious burl‑laden Icicle Tree. The park’s temperate rainforest setting, with 55 inches of rain yearly and summer fog, fosters lush ferns, blooming wildflowers, mosses, and a habitat for woodland wildlife.
