Walk among old growth coast redwoods, cooling their roots in the freshwater of Redwood Creek and lifting their crowns to reach the sun and fog. Federally protected as a National Monument since 1908, this primeval forest is both refuge and laboratory, revealing our relationship with the living landscape.
Muir Woods National Monument is world renowned for its old-growth coastal redwoods, attracting over one million visitors each year. With the park’s popularity come pressures on a fragile ecosystem representing more than 380 different plants and animals.
The incredible diversity of flora and fauna at Muir Woods can be daunting sometimes, elusive at other times. The redwoods themselves dominate the scene, but the Steller's jay often steals the show. Ladybugs clustering by the thousands on ancient horsetail ferns boggle the imagination, while the slimy banana slug is able to disgust and fascinate all at once. Plants adapt to low light levels on the forest floor, while whole plant and animal communities bustle in the canopy above our heads.
