A third of the total moisture available to local plants-including the towering redwoods-is produced by fog drip, a phenomenon in which fog droplets condense on the leaves of trees and coastal scrub.Vanilla leaf and redwood sorrel knit together and thrive in the shade beneath the giant redwoods. Northern California has a Mediterranean climate: wet winters and dry summers. The tannin in the trees repel insects, and the volume of flowers and fruits produced by plants below the canopy is limited by the shade of the redwoods. This relatively low number is due to the lack of insects.

Muir Woods is home to the Northern Spotted Owl and over 50 species of birds. You can watch the spawning rituals of salmon from the footbridges that cross the creek at intervals among redwoods. The restoration at Muir Beach is directly linked to declining salmon runs and a huge effort is being made to create a functional, self-sustaining ecosystem in the watershed. The spawning migrations begin after a heavy late fall or winter rains breach the sandbar at Muir Beach allowing fish to move upstream. Redwood Creek provides a critical spawning and rearing habitat for several threatened species, including coho or silver salmon ( Oncorhynchus kisutch) and steelhead trout ( Oncorhynchus mykiss).

During the peak spring and summer season, take the Muir Woods Shuttle.

We strongly recommend taking public transportation to Muir Woods. Muir Woods is extremely popular and parking is very limited.Wildlife residents include the endangered coho salmon fingerlings, Pacific wren, woodpeckers, owls, deer, chipmunks, skunks, river otters, and squirrels to name a few.ĪDVISORY: With numerous road-safety and watershed improvement projects happening in and around Muir Woods, visitors are strongly encouraged to use the “Plan Your Visit” and "Tips and Highlights" sections below before heading out to the woods. Several bridges cross Redwood Creek, which flows through the park year-round. The forest floor is covered in redwood sorrel, ferns, fungi, duff, and debris. In the light gaps beneath the redwood trees are red alders, California big leaf maples, tanoaks, and Douglas fir. Muir Woods National Monument was established on Januwhen President Roosevelt signed legislation to protect an old-growth coast redwood forest from destruction. Flat easy trails loop through the groves. The trees' ages range from 400 to 800 years, their height up to 250 feet. They come from around the globe to pay homage to nature in this cathedral of redwoods.
