The Muir Woods national monument is the last surviving primordial redwood forest. Located in Marin County, California. It is part of the Golden Gate National Recreation Area. It protects 554 acres (224 ha), of which 240 acres (97 ha) are old growth coast redwood (Sequoia sempervirens) forests, one of a few such stands remaining in the San Francisco Bay Area. Only a few miles north of San Francisco, in an isolated canyon, The park offers solitude, interpretive displays and programs, and numerous hiking trails. Come stroll through 1,000 year old giant trees towering 260 feet high and find out why famed naturalist John Muir called this… “…the best tree-lovers monument that could possibly be found in all the forests of the world.”
The main attraction of Muir Woods are the coast redwood (Sequoia sempervirens) trees. They are known for their height, and are related to the giant sequoia of the Sierra Nevada. While redwoods can grow to nearly 380 feet (115 m), the tallest tree in the Muir Woods is 258 feet (79 m). The trees come from a seed no bigger than that of a tomato. Most of the redwoods in the monument are between 500 and 800 years old. The oldest is at least 1,200 years old.
Redwood Creek provides a critical spawning and rearing habitat for coho or silver salmon (Oncorhynchus kisutch) and steelhead (Oncorhynchus mykiss). Steelhead are listed as threatened species (2011) in the Central California Coast distinct population segment. Coho salmon are listed as endangered in their evolutionary significant unit (2011). The creek is near the southernmost limit of coho habitat and the fish have never been stocked, so they have a distinctive DNA. The Redwood Creek salmon are Central Coast coho salmon which have been listed as federally threatened species since October 2006 and as federally endangered species in June 2005. Coho migrate from the ocean back to freshwater for a single chance at reproduction, generally after two years in the ocean. The spawning migrations begin after heavy late fall or winter rains breach the sandbar at Muir Beach allowing the fish to move upstream
The monument is managed by the National Park Service and is open year round from 8:00am to sunset. An entrance fee is charged.
