Muir Woods National Monument: Cathedral of Old-Growth Coastal Redwoods

Nestled in a secluded valley north of San Francisco in Marin County, Muir Woods National Monument protects one of the last accessible old-growth coast redwood forests near a major city. Established in 1908, this 554-acre sanctuary draws eco-travelers for its towering giants, fern-lined paths, and profound quiet amid the fog-draped trees.


A Living Mosaic of Redwood Grove and Riparian Life

Muir Woods sits at the convergence of coastal redwood forest, Redwood Creek's riparian corridor, and surrounding chaparral slopes. Ancient coast redwoods (some 400 to 1,200+ years old, up to 250+ feet tall) form a shaded cathedral with ferns, sorrel, and banana slugs below. The creek supports steelhead trout, salmon runs seasonally, and diverse birds; the understory thrives with mosses and epiphytes in the cool, moist microclimate.


Adventure With a Conservation Conscience

Flat, accessible boardwalk loops (e.g., Main Trail Bridge 2 loop, 0.5 mile) wind among monumental trees; longer routes like Bohemian Grove or Canopy View add elevation and solitude. Wheelchair/stroller-friendly sections available.

Access remains intentional: reservations required year-round for parking ($10 to $45 vehicle) or shuttle ($4 adult round-trip), $15 adult entrance fee (free under 16), purchase via GoMuirWoods.com. Pack-in/pack-out rules, no pets (service animals only), limited cell service; arrive early to avoid crowds.

Muir Woods rewards seekers of old-growth coastal redwoods hiking with timeless majesty. The hushed trails amid giants demand presence; that's the profound reward in this protected grove.
