No Drones Allowed in Park

  • The noise and sight of drones can alter other people’s enjoyment of nature.
  • A drone hovering nearby can feel intrusive and threatening.
  • Drones can capture photographs and video without someone’s permission.
  • Drones mimic the behavior of predatory birds and can frighten wildlife.

For these reasons State Park units in the Sonoma-Mendocino Coast District do not allow launching, landing or the operation of drones on State Park property.

The serene, majestic beauty of this Grove is a living reminder of the magnificent primeval redwood forest that covered much of this area before logging operations began during the 19th century. Armstrong Redwoods preserves stately and magnificent Sequoia sempervirens, commonly known as the coast redwood. These trees stand together as a testament to the wonders of the natural world. The grove offers solace from the hustle and bustle of daily life, offering the onlooker great inspiration and a place for quiet reflection.

Armstrong Redwoods image

The ancient coast redwood is the tallest living thing on our planet!  These remarkable trees live to be 500-1,000 years old, grow to a diameter of 12-16 feet, and stand from 200-250 feet tall. Some trees survive to over 2,000 years and tower above 350 feet. Coast redwoods are classified as temperate rainforests and they need wet and mild climates to survive. The rainfall in Armstrong Redwoods averages 55 inches per year and the trees are often shrouded in a mystical fog that helps to maintain the moist conditions needed for the redwoods to survive. To find out more about these magnificent trees click the link About Coast Redwoods to the right.

The reserve includes a visitor center, self-guided nature trails, and a variety of picnic facilities. While you can drive into the park, the best way to experience the dramatic effect of the towering redwoods, is to park in the lot at the park entrance and walk in for free.  Donations are accepted at the Visitor Center and at the kiosk entrance.   All of the main park features can be found along the Pioneer Nature Trail. This trail is a mile and a half long round trip, is ADA accessible and is mostly flat and level. 

Although no camping is available in Armstrong Redwood SNR, there is a campground operated by Stewards of the Coast and Redwoods located in Austin Creek State Recreation Area at Bullfrog Pond Campground (3 miles above Armstrong). Austin Creek SRA is accessed through the same entrance as Armstrong Redwoods. Austin Creek's rolling hills, open grasslands, conifers, and oaks are a beautiful and dramatic contrast to the dense canopy of the redwood grove. For more information go to Austin Creek State Recreation Area. by clicking the link on the right.  For online reservations at Bullfrog Pond Campground or any of the backcountry campsites go to

The redwood ecosystem is very fragile. Every effort is being made to preserve and protect this grove but it can only be done with your help.

Features of the Grove:

Fern Grove imageThe Tallest Tree
The Parson Jones Tree is the tallest tree in the grove, measuring more than 310 feet in height. This is longer than the length of a football field. An easy 0.1 mile walk from the park entrance.

The Oldest Tree
The Colonel Armstrong Tree is the oldest tree in the grove, estimated to be over 1,400 years old. It is named after a lumberman who chose to preserve this portion of the park in the 1870s. This magnificent tree is located within an easy half-mile walk from the park entrance.

The Icicle Tree
This tree shows the unusual burl formations often found on redwood trees. Burls can weigh many tons and grow hundreds of feet above the forest floor. Why these growths occur remains a mystery.

The Discovery Trail

Seasons/Climate/Recommended Clothing

Twin Lovers Tree imageIn summer, the weather can be variable. Morning fog can blanket the grove and cool the air while afternoon temperatures can warm up quite nicely. Many trails lead into the upper hills of Austin Creek where temperatures can soar above 100 degrees. Layered clothing, a fully charged cell phone and plenty of water is highly recommended.  Cellphone coverage is not available in all locations.

In the springtime, wildflowers are prolific, temperatures are mild and the fog is less frequent.

In winter, temperatures drop but remain moderate. Rain nourishes the grove and brings life to the many plants and ferns, turning the understory into a green, lush carpet. A sweater and rain jacket will allow you to enjoy the special tranquility found in the grove as water drops work their magic.  

Park History

During the 1870's, this area was set aside as a natural park and botanical garden by Colonel James Armstrong, a lumberman who recognized the beauty and natural value of the forests he harvested. After his death, Armstrong's daughter and the Le Baron family mounted an energetic campaign involving public meetings, rallies and car-caravans to direct public attention to the need to preserve this last remnant of the once mighty redwood forest. Their efforts were successful, and in 1917 the County of Sonoma passed an initiative to purchase the property for $80,000.

The grove was managed by Sonoma County until 1934 when the State took over. In 1936 the grove was opened to the public as Armstrong Redwoods State Park. The grove's status was changed to a reserve in 1964 when a greater understanding of its ecological significance prompted a more protective management of the resource.
