Best Time to Visit Armstrong Redwoods
Armstrong Redwoods can be visited year-round, but each season offers a different experience. The coastal redwoods create their own microclimate, keeping the reserve cooler in summer and warmer in winter than the surrounding areas.
Recommended Seasons
Spring (March-May)
Spring brings wildflowers, lush ferns, and moderate temperatures of 15-20°C (59-68°F). The forest floor comes alive with trillium, redwood sorrel, and other native plants. Rainfall decreases, making hiking more enjoyable.
Fall (September-November)
Fall offers pleasant temperatures of 18-23°C (64-73°F) and fewer crowds after the summer rush. The light filtering through the canopy creates magical scenes, and the forest has a peaceful atmosphere.
Summer (June-August)
Summer brings warmer temperatures of 20-25°C (68-77°F) and is the busiest season. The redwood canopy provides natural cooling, making it a refreshing escape from summer heat. Morning fog is common, creating ethereal scenes.
Winter (December-February)
Winter is the rainiest season with temperatures of 10-15°C (50-59°F). While there are fewer visitors, the lush moss and ferns thrive in the moisture. Some trails may be muddy, but the misty atmosphere creates a mystical experience.
Weather Considerations
The reserve receives an average of 140 cm (55 inches) of rainfall annually, mostly between November and April. Morning coastal fog is common year-round but typically burns off by midday. Temperatures rarely drop below freezing or rise above 27°C (80°F), making it a comfortable destination in any season.

Nature & Wildlife in Armstrong Redwoods
Armstrong Redwoods is more than just tall trees—it’s a complex ecosystem supporting diverse plant and animal life. The redwoods themselves create a unique microclimate that nurtures a rich understory of plants and provides habitat for numerous wildlife species.
Flora
While the coast redwoods (Sequoia sempervirens) are the stars of the reserve, they share the forest with many other plant species:
- Douglas Fir – These tall conifers often grow alongside redwoods
- Tanoak – Broadleaf evergreen trees with distinctive acorns
- California Bay Laurel – Aromatic trees with distinctive lance-shaped leaves
- Sword Ferns – Large ferns that carpet the forest floor
- Redwood Sorrel – Clover-like plants that form carpets on the forest floor
- Wild Iris – Beautiful purple flowers that bloom in spring
- Trillium – Three-petaled wildflowers that bloom in early spring
Fauna
The reserve is home to numerous animal species, though many are shy and most active at dawn and dusk:
- Black-tailed Deer – Commonly seen browsing in forest clearings
- Western Gray Squirrels – Active during daylight hours
- Banana Slugs – Bright yellow mollusks that help decompose forest matter
- Stellar’s Jays – Bold blue birds with distinctive calls
- Northern Spotted Owls – Rare and elusive forest dwellers
- Pileated Woodpeckers – Large woodpeckers that leave distinctive rectangular holes
Redwood Ecology
Coast redwoods create their own unique environment. Their canopy captures moisture from fog, which can provide up to 40% of their water needs during dry summer months. This “fog drip” also nourishes understory plants. The trees’ thick, fire-resistant bark helps them survive forest fires, and their shallow root systems interlock with neighboring trees for stability despite their great height.
Conservation Note: Armstrong Redwoods represents just a fraction of the ancient redwood forests that once covered much of coastal Northern California. Today, less than 5% of the original old-growth coast redwood forest remains, making reserves like this crucial for conservation.
Photography Tips for Armstrong Redwoods
Armstrong Redwoods offers endless photography opportunities, from capturing the scale of the massive trees to focusing on the delicate details of the forest floor. The interplay of light, fog, and ancient trees creates magical scenes throughout the day.
Best Times for Photography
- Early Morning – Morning fog and first light create ethereal scenes as sunbeams filter through the canopy
- Late Afternoon – Golden hour light adds warmth to the typically cool-toned forest

Recommended Shots
Scale Shots
Include a person (with permission) near the base of a redwood to demonstrate the tree’s enormous size. The Colonel Armstrong and Parson Jones trees are perfect for this.
Looking Up
Lie on your back and shoot straight up into the canopy for a dizzying perspective of height and converging trunks.
Forest Details
Focus on smaller elements like ferns, sorrel, mushrooms, bark textures, and the interplay of light and shadow on the forest floor.
Photography Tips
- Use a Wide-Angle Lens – To capture the full height of the trees and the expansive forest
- Bring a Tripod – The forest can be dark, requiring slower shutter speeds
