What shapes Armstrong Redwoods State Natural Reserve's weather
Above Armstrong's canyon, the weather changes fast. The ridges of Austin Creek State Recreation Area above the grove are far more exposed to the sun. State Parks warns that the upper trails can top triple digits in summer. The same afternoon can be pleasant among the redwoods and dangerously hot a couple of miles up the trail.
Armstrong Redwoods sits in one of the wettest corners of the lower Russian River. Winter storms rise over the coastal hills and drop heavy rain, the moisture that lets these trees grow so tall. On clear winter nights cold air drains into the canyon, so the grove can feel noticeably colder than town.
Tips for visiting Armstrong Redwoods State Natural Reserve
Walk or bike in for free
There is no fee to enter on foot or by bicycle. Vehicle day-use fees apply in the main lot.
Carry water above the grove
Upper Austin Creek trails can exceed 100°F in summer. Bring layers, plenty of water, and a charged phone.
Take the accessible Pioneer Trail
The mostly flat, 1.5-mile round-trip Pioneer Nature Trail is wheelchair accessible and reaches the main trees.

Armstrong Redwoods State Natural Reserve through the seasons
